The hydrosphereThe hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers.
What sphere is humans in?
***Note: Some scientists place humans in their own sphere called the "anthrosphere." For the purpose of this module, however, humans will be included as part of the biosphere. The word "biosphere" will be used in reference to all living things in Earth's system.
Why are the 4 spheres important?
The spheres are the biosphere, the geosphere, the hydrosphere, and the atmosphere. Together they are responsible for creating and maintaining the climate, geological processes, and life on Earth.
What are the 4 spheres of the Earth system?
The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. These components are also systems in their own right and they are tightly interconnected.
How are the 4 spheres connected?
The four spheres of Earth are closely connected to each other. Birds(biosphere) fly through the air (atmosphere), and water (hydrosphere) flows through the soil (lithosphere or geosphere). The spheres of the earth are closely connected to each other. A change in one sphere results in a change in two or more spheres.
What sphere is rain?

What is the highest sphere?
Exosphere. Located between about 700 and 10,000 kilometers (440 and 6,200 miles) above Earth's surface, the exosphere is the highest layer of Earth's atmosphere and, at its top, merges with the solar wind.
Is rain a hydrosphere or atmosphere?
The Hydrosphere includes the oceans, seas, lakes, rivers, streams, and other bodies of water. Water in the form of rain, snow, clouds, and atmospheric moisture is also part of the hydrosphere. Along the margins of continents, a Continental shelf, very gentle in slope, extends outward to a depth of a few hundred feet.
What are the 4 spheres of the Earth system?
The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. These components are also systems in their own right and they are tightly interconnected.

What happens when you take rocks from the lithosphere and erode them over time?
If you take rocks from the lithosphere and erode them over time, you get soil in the pedosphere. Soil is just weathered rock. It’s where plants establish their roots. So il also has living things like bugs, worms, roots and dead leaves. This organic material is among the many so il formation factors.
How old is the lithosphere?
The lithosphere is hard, brittle and old. The oldest rocks in the lithosphere are more than 4 billion years old. If you could speed up time, you’d see rocks in the lithosphere continuously cycling from within the planet. The rock cycle builds all types of rocks, including igneous, metamorphic and sedimentary rocks. 5.
What is the geosphere?
The geosphere is the whole outer shell of Earth. We can divide it into the continental and oceanic crust. The oceanic crust consists of the youngest rocks on Earth. This is where lava spews out at mid-oceanic ridges deep within the ocean. But the continental crust is the opposite.
What are the living things in the biosphere?
All living things on land, air, and oceans make up the biosphere. In every ecosystem, organisms rely on each other as part of an intricate food web. On land, herbivores feed on plants. Then, predators consume herbivores. At the top of the food chain, humans and apex predators dominate.
Why is the atmosphere denser than the air?
If you look at the atmosphere’s chemical composition, it’s mostly nitrogen and oxygen. Air is denser closer to Earth because of Earth’s gravitational pull. As you move outwards, the air becomes less dense.
What is the atmosphere of Earth?

How much does the atmosphere weigh?
The atmosphere has a mass of about 5.15 × 10 18 kg, three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner with increasing altitude, with no definite boundary between the atmosphere and outer space.
How did plate tectonics influence the long-term evolution of the atmosphere?
The constant re-arrangement of continents by plate tectonics influences the long-term evolution of the atmosphere by transferring carbon dioxide to and from large continental carbonate stores. Free oxygen did not exist in the atmosphere until about 2.4 billion years ago during the Great Oxygenation Event and its appearance is indicated by the end of the banded iron formations .
What is the study of the atmosphere called?
The study of Earth's atmosphere and its processes is called atmospheric science (aerology), and includes multiple subfields, such as climatology and atmospheric physics.

What is the atmosphere made of?
The atmosphere of Earth, which we casually refer to as simply ‘air’, is actually made up of a mixture of gases and vapours. The Earth’s atmosphere forms a barrier, or bubble around the Earth, and is held there by the force of gravity. This keeps the vapours of the atmosphere from escaping into outer space. It is also this atmosphere which makes the ...
What are the different types of life in the biosphere?
This life is then divided into a series of classifications: kingdoms, phylum, classes, orders, families, genus, and species. There are 5 different kingdoms, known as: animal, plant, fungi, protist and monera, and all of these encompass the entirety of the biosphere. The large biosphere is then further broken down into biomes and ecosystems, which are more specific working systems of animals and plants in any given area. Together, they form an intricate web of life which, when kept in balance, allows our Earth to run in harmony.

Hydrosphere. Water cycle allows the hydrosphere to function. The hydrosphere is the water sphere of Earth. This includes the total amount of water that can be found on the whole planet, from that on the surface - like in lakes, oceans, rivers etc. as well as water underground, and in the air.
What are the layers of the lithosphere?
It more specifically refers to the rocky outer surface of the Earth’s crust, and upper portion of the mantle. The Earth itself is split into several layers: the crust, upper and main mantle, the outer core and the inner core.
What is the atmosphere on Earth?
Matt Rosenberg. Updated January 26, 2019. Earth is surrounded by its atmosphere, which is the body of air or gases that protects the planet and enables life. Most of our atmosphere is located close to Earth's surface, where it is most dense. It has five distinct layers.
What is the amount of oxygen in the atmosphere?
It's where weather happens and contains the air humans breathe. The air of our planet is 79 percent nitrogen and just under 21 percent oxygen; the small amount remaining is composed of carbon dioxide and other gases. The temperature of the troposphere decreases with height.
What is the boundary between the troposphere and the stratosphere?
Between each layer of the atmosphere is a boundary. Above the troposphere is the tropopause, above the stratosphere is the stratopause, above the mesosphere is the mesopause, and above the thermosphere is the thermopause. At these "pauses," maximum change between the "spheres" occur.
What is the temperature of the mesosphere?
Temperatures in the mesosphere reach a low of -130 degrees Fahrenheit (-90 C).
What layer of the atmosphere is above the Earth's surface?
Above the troposphere is the stratosphere, which extends to about 31 miles (50 km) above the Earth's surface. This layer is where the ozone layer exists and scientists send weather balloons. Jets fly in the lower stratosphere to avoid turbulence in the troposphere.
How high is the thermosphere?
The thermosphere rises several hundred miles above the Earth's surface, from 56 miles (90 km) up to between 311 and 621 miles (500–1,000 km). Temperature is very much affected by the sun here; it can be 360 degrees Fahrenheit hotter (500 C) during the day than at night. Temperature increases with height and can rise to as high as 3,600 degrees Fahrenheit (2000 C). Nonetheless, the air would feel cold because the hot molecules are so far apart. This layer is known as the upper atmosphere, and it is where the auroras occur ( northern and southern lights).
Which layer of the atmosphere is closest to the Earth?
Troposphere. The layer of the atmosphere closest to the Earth is the troposphere. It begins at the surface of the Earth and extends out to about 4 to 12 miles (6 to 20 km). This layer is known as the lower atmosphere. It's where weather happens and contains the air humans breathe.
Overview
Stratification
In general, air pressure and density decrease with altitude in the atmosphere. However, the temperature has a more complicated profile with altitude, and may remain relatively constant or even increase with altitude in some regions (see the temperature section, below). Because the general pattern of the temperature/altitude profile, or lapse rate, is constant and measurable by mean…
Composition
The three major constituents of Earth's atmosphere are nitrogen, oxygen, and argon. Water vapor accounts for roughly 0.25% of the atmosphere by mass. The concentration of water vapor (a greenhouse gas) varies significantly from around 10 ppm by mole fraction in the coldest portions of the atmosphere to as much as 5% by mole fraction in hot, humid air masses, and concentrations of …
Physical properties
The average atmospheric pressure at sea level is defined by the International Standard Atmosphere as 101325 pascals (760.00 Torr; 14.6959 psi; 760.00 mmHg). This is sometimes referred to as a unit of standard atmospheres (atm). Total atmospheric mass is 5.1480×10 kg (1.135×10 lb), about 2.5% less than would be inferred from the average sea level pressure and Earth's area of 51007.2 m…
Optical properties
Solar radiation (or sunlight) is the energy Earth receives from the Sun. Earth also emits radiation back into space, but at longer wavelengths that humans cannot see. Part of the incoming and emitted radiation is absorbed or reflected by the atmosphere. In May 2017, glints of light, seen as twinkling from an orbiting satellite a million miles away, were found to be reflected light from ice crystals i…
Circulation
Atmospheric circulation is the large-scale movement of air through the troposphere, and the means (with ocean circulation) by which heat is distributed around Earth. The large-scale structure of the atmospheric circulation varies from year to year, but the basic structure remains fairly constant because it is determined by Earth's rotation rate and the difference in solar radiation betwee…
Evolution of Earth's atmosphere
The first atmosphere consisted of gases in the solar nebula, primarily hydrogen. There were probably simple hydrides such as those now found in the gas giants (Jupiter and Saturn), notably water vapor, methane and ammonia.
Outgassing from volcanism, supplemented by gases produced during the late heavy bombardment of Earth by huge asteroids, produced the next atmosphere…
Images from space
On October 19, 2015, NASA started a website containing daily images of the full sunlit side of Earth at https://epic.gsfc.nasa.gov/. The images are taken from the Deep Space Climate Observatory (DSCOVR) and show Earth as it rotates during a day.
