From the ground level they are:
- Troposphere:- (0 -12 km) or (0 to 7 miles)
- Stratosphere :- (12 -50 km) or (7 to 31 miles)

What are the different spheres of the atmosphere?
What are the 5 spheres in the atmosphere?
- The atmosphere is made up of invisible gases.
- The majority of the atmosphere is MADE up of oxygen and nitrogen.
- There are 5 layers in the atmosphere: Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere.
How many layers does an atmosphere have?
This is also called the atmosphere. It mainly consists of oxygen and nitrogen. We humans and many animals need oxygen to breathe and survive. The atmosphere consists of five layers. Each of these layers has its own characteristics and benefits the earth in different ways. The troposphere. The first and thinnest layer around our earth is the troposphere.
What are 5 facts about the atmosphere?
What are 5 facts about the atmosphere?
- Mixture. The Earth’s Atmosphere is 480 km thick, and it is made of a mix of about 16 gases:
- The Five Layers.
- High Altitude, Thin Atmosphere.
- Karman Line.
- Troposphere is Denser.
- Earth’s Temperature is Rising.

- Chlorine Affects Ozone.
What are the 7 layers of Earth?
What Are The Layers Of The Earth?
- Crust. The crust of the Earth is the area that is arguably best known by scientists, and certainly the one the general public is the most familiar with, as it ...
- Mantle. The mantle makes up 84 percent of the Earth’s volume, and consists of both solid and molten rock known as magma.
- Outer Core. ...
- Inner Core. ...
How are layers of the atmosphere classified?
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.
What are the 5 layers of atmosphere and their characteristics?
Layers of Earth's AtmosphereTroposphere. The troposphere is the lowest layer of our atmosphere. ... Stratosphere. The next layer up is called the stratosphere. ... Mesosphere. Above the stratosphere is the mesosphere. ... Thermosphere. The layer of very rare air above the mesosphere is called the thermosphere. ... Exosphere. ... Ionosphere.
What are the layers of atmosphere and its meaning?
An atmosphere can be defined as the blanket of gas on the surface of a planet. The Earth's atmosphere is the mixture of gases that surrounds the planet. The Earth's atmosphere contains mainly 5 layers which are troposphere, stratosphere, mesosphere, thermosphere and exosphere.
What are the characteristics of each layer of earth?
The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.
What are the 4 characteristics of troposphere?
Of all five layers, the troposphere has the highest density, greatest air pressure, 75% of the atmospheric mass, nearly all water vapor, and a temperature range from 62 to -60 degrees F. The temperature in the troposphere decreases steadily with altitude.
What is the characteristics of stratosphere?
The stratosphere is very dry air and contains little water vapor. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere. Polar stratospheric clouds (PSCs) are the exception. PSCs appear in the lower stratosphere near the poles in winter.
What are the characteristics of troposphere?
The troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth. It's thinnest at the North and South Pole. This layer has the air we breathe and the clouds in the sky. The air is densest in this lowest layer.
What are the characteristics of thermosphere?
The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity.
What layer of the atmosphere is the thermosphere?
The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.
Which layer of the atmosphere absorbs and scatters ultraviolet radiation?
The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. The mesosphere starts just above the stratosphere and extends to 85 kilometers (53 miles) high. Meteors burn up in this layer. The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high.
Which part of the atmosphere is the most dense?
The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high.
How far is the upper limit of the atmosphere?
This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km (6,200 mi).
What layer of the atmosphere is above the Earth's surface?
If we start from the top of the troposphere and go further into the sky, we reach the layer known as the stratosphere. If we start from the top of the troposphere and go further into the sky, we reach the layer known as the stratosphere. This layer goes up around 50 km above the Earth’s ground. In this layer, the temperature rises as you go further ...
Which layer of the atmosphere is the lowest?
1. Troposphere. This is the first and the lowest layer of Earth’s atmosphere. This is the first and the lowest layer of Earth’s atmosphere. All life on this planet is affected by the changes that happen in this layer, as all the weather changes take place in the troposphere. It starts from the ground (or sea level) of our planet ...
How to think about the atmosphere above our planet?
The easiest way to think about the atmosphere above our planet is to imagine an invisible shield that protects our planet from all the bad stuff that floats around in the universe. Planes usually fly in the lowest parts of the stratosphere layer. The air is a bit thinner, so there is not much resistance, which makes the planes fly faster.
What is the name of the layer that goes up to 85 km above the surface of the Earth?
3. Mesosphere . As the name suggests, we are halfway up our atmosphere layers when we reach this part. As the name suggests, we are halfway up our atmosphere layers when we reach this part. The mesosphere goes up to 85 km above the surface of our planet, and the temperatures here behave as they do in the troposphere.
What is the exosphere?
Exosphere. Unlike other layers, which are mostly distinguishable from one another, it is hard to say how far the exosphere is from the surface of the planet. Unlike other layers, which are mostly distinguishable from one another, it is hard to say how far the exosphere is from the surface of the planet.
What is the layer above the Earth's surface called?
The layer that is located between 500 and 1000 km above the Earth’s level is known as the thermosphere. You have guessed it, high temperatures are the name of the game here.
Which layer of the atmosphere protects us from radiation?
The ozone layer, the one that protects us from radiation that comes from the Sun and outer space, is found in the stratosphere. The atmosphere of Earth is divided into several different layers. The easiest way to think about the atmosphere above our planet is to imagine an invisible shield that protects our planet from all the bad stuff ...
Which part of the atmosphere contains almost all of the mass?
The troposphere contains almost all of the mass of the atmosphere.
