Earth's atmosphere is divided into layers order these layers of the atmosphere from closest to Earth to the exosphere
The layers of Earth's atmosphere, from closest to Earth to exosphere, are as follows:
1. Troposphere: This is the lowest layer, extending from the Earth's surface up to an altitude of about 7-20 kilometers (4-12 miles). Weather occurs largely in this layer, and it contains about 75% of the atmosphere's mass.
2. Stratosphere: The stratosphere exists above the troposphere and extends from about 20-50 kilometers (12-31 miles) above the Earth's surface. It contains the ozone layer, which absorbs and blocks much of the Sun's harmful ultraviolet (UV) radiation.
3. Mesosphere: Above the stratosphere lies the mesosphere, reaching approximately 50-85 kilometers (31-53 miles) in altitude. This layer is characterized by a decrease in temperature with increasing altitude, and it is where meteors burn up upon entry into the atmosphere.
4. Thermosphere: Extending from about 85 kilometers (53 miles) upward, the thermosphere is the next layer. Although it has an extremely low density of molecules, it experiences intense heating from the Sun's radiation. Temperatures in this layer can reach thousands of degrees Celsius, but it would not feel hot to an observer due to the low density of particles.
5. Exosphere: The outermost layer of Earth's atmosphere is the exosphere, which gradually extends upward into space. It starts around 600 kilometers (370 miles) above the Earth's surface and continues indefinitely. The exosphere contains mostly low-density hydrogen and helium gases, and it gradually merges with the vacuum of space.
The Earth's atmosphere is divided into five main layers, starting from the closest to the Earth's surface and moving outward:
1. Troposphere: This is the lowest layer of the atmosphere, extending from the Earth's surface up to around 8-15 kilometers (5-9 miles) in altitude, depending on location and season. The troposphere contains most of our weather, including clouds, precipitation, and the air we breathe.
2. Stratosphere: Above the troposphere lies the stratosphere, extending from the top of the troposphere (around 8-15 kilometers) up to approximately 50 kilometers (31 miles) in altitude. Within the stratosphere, you can find the ozone layer, which absorbs most of the Sun's harmful ultraviolet radiation.
3. Mesosphere: The mesosphere stretches from the top of the stratosphere (around 50 kilometers) to about 85 kilometers (53 miles) above the Earth's surface. This layer is where meteors typically burn up upon entering the Earth's atmosphere.
4. Thermosphere: Above the mesosphere is the thermosphere, extending from about 85 kilometers up to approximately 600 kilometers (373 miles) in altitude. In this layer, the temperature increases with altitude due to the absorption of solar radiation.
5. Exosphere: The outermost and highest layer of the Earth's atmosphere is the exosphere. It starts at around 600 kilometers (373 miles) and continues on indefinitely, gradually merging with interplanetary space. The densities of gas molecules in the exosphere are extremely low.
So, the correct order of Earth's atmospheric layers from closest to the surface to the exosphere is: troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The layers of Earth's atmosphere from closest to Earth to the exosphere are as follows:
1. Troposphere: The troposphere is the layer closest to the Earth's surface and extends upward to an average height of about 8-15 kilometers (5-9 miles). This is where weather occurs, and it contains the majority of the Earth's atmospheric mass.
2. Stratosphere: Above the troposphere lies the stratosphere, which extends from the top of the troposphere to approximately 50 kilometers (31 miles) above the Earth's surface. The ozone layer is located in the lower stratosphere and helps absorb harmful ultraviolet (UV) radiation from the Sun.
3. Mesosphere: The mesosphere is situated above the stratosphere and extends up to approximately 85 kilometers (53 miles) above the Earth's surface. This is the layer where most meteors burn up upon entry into the atmosphere.
4. Thermosphere: The thermosphere begins around 85 kilometers (53 miles) and extends to about 600 kilometers (373 miles) above the Earth's surface. It is characterized by increasing temperatures with altitude due to absorption of intense solar radiation. The International Space Station orbits within this layer of the atmosphere.
5. Exosphere: The exosphere is the outermost layer of Earth's atmosphere and extends from the upper thermosphere to about 10,000 kilometers (6,200 miles) above the Earth's surface. It gradually transitions into the vacuum of space and contains primarily lighter gases such as helium and hydrogen.
Remember, the key to remembering the layers of Earth's atmosphere is to start from the surface and move outward in the order described above.
