Jan 21, 2023 · A 1-cm 2 cross section of the earth’s surface supports a column weighing 1030 g; the total mass of the atmosphere is about 5.27 x 10 21 g. About 80% of the mass of the atmosphere resides in the first 10 km; this well-mixed region of fairly uniform composition is known as the troposphere.
- Troposphere. 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.
- 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.
- Mesosphere. 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.
- Thermosphere. 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.
Jan 22, 2013 · Diagram of the layers within Earth’s atmosphere. Troposphere. 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 first atmosphere, during the Early Earth's Hadean eon, consisted of gases in the solar nebula, primarily hydrogen, and probably simple hydrides such as those now found in the gas giants (Jupiter and Saturn), notably water vapor, methane and ammonia.
- Troposphere. Temperature: 62°F (17°C) around the lowest point to -60°F (-51°C) near the top. The troposphere is the lowest layer of the atmosphere, and it is where we live.
- Stratosphere. Temperature: -60°F (-51°C) near the tropopause to 5°F (-15°C) near the next layer. Lies just above the troposphere, extending up to 31 miles (50 km) high.
- Mesosphere. Temperature: Ranges from 5°F (-15°C) to -148°F (-100°C) as one ascends up the layer. The mesosphere extends from just above the stratosphere to 53-62 miles (85-100 km) high.
- Thermosphere. Temperature: The temperatures in this layer depend on solar activity and can get as hot as 930°F (500°C) to 3,600°F (2,000°C) near the upper thermosphere.
The layers of the atmosphere: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. NOAA. Troposphere. The troposphere is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level.
May 3, 2022 · The atmosphere is the layer of gases that surround Earth. The five layers of the atmosphere, in order from the ground up, are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The atmosphere extends to roughly 100 km or 62 miles. This is the Kármán line, which marks the beginning of space.
