How long is the Sun's sun cycle?
The Sun has an 11-year sunspot cycle, which causes about 0.1% of the variation in the Sun’s output. 1 The solar cycle is incorporated into climate models. Greenhouse gas emissions.
What is the source of heat on Earth?
Solar radiation is the source of heat for planet Earth. Scientists also use evidence from proxy measurements, such as sunspot counts going back centuries and ancient tree rings, to measure the amount of Sun that reaches Earth’s surface.
Why is ocean circulation important?
This highlights the importance of ocean circulation in maintaining regional climates. Ice loss. Due to the strong positive feedback of the ice albedo, if enough ice melts, causing Earth’s surface to absorb more and more heat, then we may hit a point of no return. Shrinking ice sheets contribute to sea level rise.
What would happen if the Earth's surface was warmer?
A warmer climate could cause more water to be held in the atmosphere, leading to an increase in cloudiness and altering the amount of sunlight that reaches the surface of the Earth. Less heat would get absorbed, which could slow the increased warming. Precipitation.
How do clouds affect the Earth's climate?
Clouds have an enormous impact on Earth's climate, reflecting about one-third of the total amount of sunlight that hits the Earth's atmosphere back into space. Even small changes in cloud amount, location and type could have large consequences.
What is Earth System Science?
Earth System Science fosters synthesis and the consideration of a holistic model in which disciplinary process and action lead to synergistic interdisciplinary relevance. However, the development both conceptually and physically of the Earth system model and its quantitative assessment in the classroom and laboratory is a continuing, formative processes which requires nurturing and commitment to eclectic learning beyond one's discipline. The intersection of disciplinary specialties often provides the most fertile and interesting fields for study, but is easily sidetracked by traditional disciplinary interests.
When did NASA start cataloging the Earth system?
In the mid-1980s NASA began a systems approach to cataloging the elements of the Earth system, their linkages, dependencies and fluxes. This simplified version focuses on the physical elements of the system, but relegates human processes to a simple box. A more complete version, which only begins to hint at the true complexity and interdependencies of the complete system, appears below. (NASA, 1988)
What is the Earth system?
Scientists increasingly view Earth as a dynamic system – a combination of interrelated, interdependent or interacting parts forming a collective whole or entity. On a macro level, the Earth system maintains its existence and functions as a whole through the interactions of its parts, called components. At a lower level or micro level, it is helpful to think of the Earth system in terms of four central components known as the subsystems – the hydrosphere, geosphere, atmosphere and biosphere.
What are the four subsystems of the Earth system?
At a lower level or micro level, it is helpful to think of the Earth system in terms of four central components known as the subsystems – the hydrosphere, geosphere, atmosphere and biosphere. These subsystems are interconnected by processes and cycles, which, over time, intermittently store, transform and/or transfer matter ...
How many subsystems are there in the water cycle?
In this video, 4 New Zealand scientists talk about how the water cycle is part of Earth’s system. They point out that Earth’s system consists of 4 subsystems – the geosphere, hydrosphere, atmosphere and biosphere – which all interact with each other.
What is the water cycle?
The water cycle is the result of a collection of connected processes that distribute water and energy throughout the Earth system in cyclic patterns. Over time, on-going and repeated change in the distribution and form of water and energy around the globe is caused by processes like evaporation, condensation, freezing, melting, convection currents and infiltration.
What is an example of an unstable system?
For example, a glacier is a relatively unstable system – if the temperature in the atmosphere rises above the melting point of ice, the glacier melts and decreases in ice and the glacier retreats.
How does water affect the Earth?
Water in the Earth system is influencing all aspects of life on Earth. Pathways, storage, transfers and transformations have an effect on the global climate and human welfare. Within this interactive 4 scientists talk about some of the complex aspects of the water cycle.
Where does energy come from?
The energy that drives these processes comes mainly from the Sun and sometimes from energy sources within the Earth. Examples of some of these processes include evaporation, erosion, convection currents, transpiration, photosynthesis or weathering. They can occur at different rates and in different places over time.
Why study Earth System Science?
Beginning to perceive Earth as a system can begin with something as simple as when we first feel warmth from sunshine or get wet standing in the rain. However, truly understanding Earth as a system—Earth System Science—requires a quantitative exploration of the connections among all parts of the system: air, water, land, and life.
What will I Learn?

What are the main systems of the Earth?
There are five main systems, or spheres, on Earth. The first system, the geosphere , consists of the interior and surface of Earth, both of which are made up of rocks. The limited part of the planet that can support living things comprises the second system; these regions are referred to as the biosphere. In the third system are the areas of Earth that are covered with enormous amounts of water, called the hydrosphere. The atmosphere is the fourth system, and it is an envelope of gas that keeps the planet warm and provides oxygen for breathing and carbon dioxide for photosynthesis. Finally, there is the fifth system, which contains huge quantities of ice at the poles and elsewhere, constituting the cryosphere. All five of these enormous and complex systems interact with one another to maintain the Earth as we know it.
Which system of the Earth is covered with water?
In the third system are the areas of Earth that are covered with enormous amounts of water, called the hydrosphere. The atmosphere is the fourth system, and it is an envelope of gas that keeps the planet warm and provides oxygen for breathing and carbon dioxide for photosynthesis.
What are the two parts of the biosphere?
Both the geosphere and hydrosphere provide the habitat for the biosphere, a global ecosystem that encompasses all the living things on Earth. The biosphere refers to the relatively small part of Earth’s environment in which living things can survive. It contains a wide range of organisms, including fungi, plants, and animals, that live together as a community. Biologists and ecologists refer to this variety of life as biodiversity. All the living things in an environment are called its biotic factors. The biosphere also includes abiotic factors, the nonliving things that organisms require to survive, such as water, air, and light.
How does the hydrosphere and geosphere interact?
When a parcel of air in the atmosphere becomes saturated with water, precipitation, such as rain or snow, can fall to Earth’s surface. That precipitation connects the hydrosphere with the geosphere by promoting erosion and weathering, surface processes that slowly break down large rocks into smaller ones. Over time, erosion and weathering change large pieces of rocks—or even mountains—into sediments, like sand or mud. The cryosphere can also be involved in erosion, as large glaciers scour bits of rock from the bedrock beneath them. The geosphere includes all the rocks that make up Earth, from the partially melted rock under the crust, to ancient, towering mountains, to grains of sand on a beach.

What are the most common features of Earth?
When observed from space, one of Earth’s most obvious features is its abundant water . Although liquid water is present around the globe, the vast majority of the water on Earth, a whopping 96.5 percent, is saline (salty) and is not water humans, and most other animals, can drink without processing. All of the liquid water on Earth, both fresh and salt, makes up the hydrosphere, but it is also part of other spheres. For instance, water vapor in the atmosphere is also considered to be part of the hydrosphere. Ice, being frozen water, is part of the hydrosphere, but it is given its own name, the cryosphere. Rivers and lakes may appear to be more common than are glaciers and icebergs, but around three-quarters of all the fresh water on Earth is locked up in the cryosphere.
What are some examples of intertwined systems?
One specific example of interaction between all the spheres is human fossil fuel consumption.

What was the first report of NASA's ESSC?
The earliest reports of NASA's ESSC, Earth System Science: Overview (1986), and the book-length Earth System Science: A Closer View (1988), constitute a major landmark in the formal development of Earth system science.
What is the role of geology in science?
As geology developed as a science, understanding of the interplay of different facets of the Earth system increased, leading to the inclusion of factors such as the Earth's interior, planetary geology and living systems .
What is the behaviour of the Earth System?
Non-linear: The behaviour of the Earth System is typified by strong non-linearities. This means that abrupt change can result when relatively small changes in a 'forcing function' push the System across a ' threshold '.
What is the application of Earth system science?
Earth system science ( ESS) is the application of systems science to the Earth. In particular, it considers interactions and 'feedbacks', through material and energy fluxes, between the Earth's sub-systems' cycles, processes and "spheres"— atmosphere, hydrosphere, cryosphere, geosphere, pedosphere, lithosphere, biosphere, and even the magnetosphere —as well as the impact of human societies on these components. At its broadest scale, Earth system science brings together researchers across both the natural and social sciences, from fields including ecology, economics, geography, geology, glaciology, meteorology, oceanography, climatology, paleontology, sociology, and space science. Like the broader subject of systems science, Earth system science assumes a holistic view of the dynamic interaction between the Earth's spheres and their many constituent subsystems fluxes and processes, the resulting spatial organization and time evolution of these systems, and their variability, stability and instability. Subsets of Earth System science include systems geology and systems ecology, and many aspects of Earth System science are fundamental to the subjects of physical geography and climate science.

Applications
Function
- These subsystems are interconnected by processes and cycles, which, over time, intermittently store, transform and/or transfer matter and energy throughout the whole Earth system in ways that are governed by the laws of conservation of matter and energy. The energy that drives these processes comes mainly from the Sun and sometimes from energy sources within the Earth.
Examples
- Examples of some of these processes include evaporation, erosion, convection currents, transpiration, photosynthesis or weathering. They can occur at different rates and in different places over time.
Summary
- A cycle is a collection of connected, on-going processes that circulates a common component throughout a system such cycles are continuous with no beginning or end. Examples in the Earth system include the rock cycle, the food chain, the carbon cycle, the nitrogen cycle, the water cycle and energy cycles.
Introduction
- Systems can range in complexity, and Earths subsystems are all dynamic. Key to understanding the complexity of the Earth system is that manipulation in one part of a subsystem can cause effects in other parts of that subsystem and/or the other subsystems, sometimes in ways that are quite unexpected. This response occurs because the subsystem attempts to maintain its stabilit…
Definition
- This degree of response also describes how stable or unstable these systems are. For example, a glacier is a relatively unstable system if the temperature in the atmosphere rises above the melting point of ice, the glacier melts and decreases in ice and the glacier retreats. In contrast, a tree is a relatively stable system that regulates environmental changes due to water shortage, fo…
Impact
- On a bigger scale, the rising temperature in the atmosphere in a region can bring on a cascade of environmental changes to restore equilibrium across the subsystems, such as changes in evaporation and transpiration rates, weather patterns such as winds and precipitationsalinity of water bodies like lakes and seas, and type of species and numbers of organisms. Each respons…
Significance
- The distribution of water is also closely linked to the distribution of other forms of matter, particularly dissolved materials in rivers, lakes and groundwater. Human activity such as agriculture, irrigation, industrial processes, sea transport and sewage disposal can impact on the components and processes of the water cycle in a number of ways consider the impact of powe…
Criticism
- Research into students learning about the water cycle indicates that many students have an incomplete picture of the water cycle and hold many misconceptions. Their thinking is often naïve, and few can recognise the complexities involved. Students may only represent the upper part of the water cycle (evaporation, condensation and rainfall) and ignore the less visible groundwater, …
Issues
- Where groundwater is acknowledged, it is often seen as a static, unchanging component of the water cycle. Students may also struggle with water chemistry throughout the cycle ideas about dissolving and purification through percolation and/or evaporation can be problematic. At times, students also underestimate the impact of human activities on the water cycle.
Curriculum
- Before starting teaching the water cycle, students need to understand some of the basic scientific ideas underpinning the concept of the Earth system and its four subsystems. Students could engage in the activities Building a water cycle and Constructing an aquifer model, before tracing the many possible paths of an imaginary water molecule within the water cycle in order to identi…
Future
- An extension activity could be to learn more about parts of the water cycle and how it affects the subsystem of system Earth by exploring the article Humans and the water cycle.
