- 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.
- Troposphere. The troposphere is the layer that we live in. The troposphere starts at ground level and extends about 12 km upwards. This is where all weather occurs and it’s the air that we breathe.
- Stratosphere. From about 12 km to 50 km upwards is the stratosphere. In this layer, the jet stream blows strong winds eastward. Airplanes use this layer of the atmosphere when they travel from west to east.
- Mesosphere. The mesosphere is the coldest region of Earth’s atmosphere. It’s somewhere close to -100 degrees Celsius. In the mesosphere, scientists send unmanned balloons to measure the temperature.
- Thermosphere. The thickest layer in the atmosphere is the thermosphere starting at about 80 km and going upwards. This is where the UV radiation from the sun turns to heat causing the air to be very hot.
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.
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 five main layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Mainly, temperature determines the altitude of these layers. The atmosphere is fluid and changes according to season, day/night cycle, and other factors, so the lower and upper limits of each layer shift.
Temperature determines the five main layers, but the atmosphere contains other layers, too. 1. Ozone Layer: The ozone layer is within the lower stratosphere. In this region, ozone concentration ranges from 2 to 8 parts per million. The layer’s altitude is from 15–35 km (9.3–21.7 mi), although its thickness varies geographically and seasonally. It i...

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.
Dec 9, 2003 · The Earth's layers of atmosphere differ in chemical composition and temperature. They combine to create a protective sheild that maintains our delicate energy balance essential for life on Earth. Most weather occures in the nearest layer, the troposphere (0-7 miles).
