- 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.
- Exosphere. This is the outermost layer of the atmosphere. It extends from about 375 miles (600 km) to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth.
- Thermosphere. Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere, known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the Earth.
- Mesosphere. This layer extends from around 31 miles (50 km) above the Earth's surface to 53 miles (85 km). The gases that comprise this layer continue to become denser as one descends.
- Stratosphere. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). This layer holds 19 percent of the atmosphere's gases but very little water vapor.
Dec 11, 2019 · Earth’s atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere.
May 13, 2024 · 1. Troposphere. The troposphere is the lowermost atmospheric layer. The troposphere holds all the air plants need for photosynthesis and animals need to breathe. Earth’s weather occurs in this layer, as it is where much of the atmospheric mass, including most of the water vapor, is found.
Oct 2, 2019 · Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere. Earth’s troposphere extends from Earth’s surface to, on average, about 12 kilometers (7.5 miles) in height, with its height lower at Earth’s ...
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.
Earth's atmosphere is composed of a series of layers, each with its own specific traits. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The exosphere gradually fades away into the realm of interplanetary space.
