Which is the correct order of atmospheric layers from the bottom to the top?
Bottom to top:
Troposphere-Stratosphere-Mesosphere-Thermosphere-Exosphere
Hope this helps :)
The correct order of atmospheric layers from the bottom to the top is as follows:
1. Troposphere: This is the lowest layer of the atmosphere, extending from the Earth's surface up to an average altitude of about 11 kilometers (7 miles). It contains most of the Earth's weather systems and is also where we live and where most of the air we breathe exists.
2. Stratosphere: The stratosphere is located above the troposphere, extending from about 11 kilometers (7 miles) up to about 50 kilometers (31 miles) above the Earth's surface. It contains the ozone layer, which helps to absorb and filter out most of the Sun's harmful ultraviolet radiation.
3. Mesosphere: The mesosphere is situated above the stratosphere, reaching approximately 50 kilometers (31 miles) up to 85 kilometers (53 miles) above the Earth's surface. This layer is known for its extreme cold temperatures and is where meteors burn up upon entering the Earth's atmosphere.
4. Thermosphere: The thermosphere is located above the mesosphere, extending from about 85 kilometers (53 miles) up to 600 kilometers (373 miles) above the Earth's surface. It is characterized by very high temperatures due to the absorption of intense ultraviolet and X-ray radiation from the Sun.
5. Exosphere: The exosphere is the outermost layer of the Earth's atmosphere, extending from the top of the thermosphere outward into space. It is a transition zone between the Earth's atmosphere and outer space and consists mainly of extremely low-density gas molecules.
The correct order of atmospheric layers from the bottom to the top is as follows:
1. Troposphere: This is the lowest layer of the atmosphere, extending from the Earth's surface up to about 10-15 kilometers (6-9 miles) above sea level. It is where weather phenomena occur, and the temperature generally decreases with altitude.
2. Stratosphere: Located above the troposphere, the stratosphere spans from about 15-50 kilometers (9-31 miles) above sea level. It contains the ozone layer, which absorbs and blocks most of the Sun's harmful ultraviolet radiation. The temperature increases with altitude in this layer.
3. Mesosphere: Above the stratosphere, the mesosphere extends from about 50-85 kilometers (31-53 miles) above sea level. The temperature decreases with altitude and it is the layer where meteors burn up as they enter Earth's atmosphere.
4. Thermosphere: The thermosphere starts around 85 kilometers (53 miles) above sea level and extends upwards until about 600 kilometers (372 miles). This layer experiences extremely high temperatures due to absorption of the Sun's energetic ultraviolet and X-ray radiation. However, it would not feel hot to human bodies due to its low density.
5. Exosphere: The exosphere is the outermost layer of the atmosphere, starting around 600 kilometers (372 miles) above sea level and extending indefinitely into space. In this layer, the atmosphere gradually thins out until it merges with the vacuum of outer space.
