Admin What layer of the atmosphere supports life?
Troposphere
d) Troposphere: the atmospheric layer that supports life. Home of the biosphere. Holds 90% of total mass of atmosphere and all water vapor, clouds, weather and air pollution.
What is the thin layer of the atmosphere?
The troposphere is also the thinnest layer, only about 10 miles high. The second layer up from the ground is the stratosphere. This layer extends from about 10-30 miles, and unlike the troposphere, it increases in temperature with elevation. It starts out from about -60°F at the bottom to about 32°F, at the top).
What is the thin layer around the Earth called?
Earth is surrounded by invisible gases that form a thin protective blanket that we call the atmosphere. It contains the oxygen that we breath as well as other important gases such as nitrogen, carbon dioxide, water vapor, and ozone.
Which is the thinnest layer of the atmosphere?
As you might imagine, the “air” in the exosphere is very, very, very thin, making this layer even more space-like than the thermosphere. In fact, the air in the exosphere is constantly – though very gradually – “leaking” out of Earth’s atmosphere into outer space.
What are the different layers of the atmosphere?
Layers of Earth’s atmosphere are divided into five different layers as: 1 Exosphere 2 Thermosphere 3 Mesosphere, 4 Stratosphere 5 Troposphere. More
Why is the atmosphere important to all life on Earth?
“ Atmosphere is a protective layer of gases that shelters all life on Earth, keeping temperatures within a relatively small range and blocking out harmful rays of sunlight.” An atmosphere is a blanket of gases that surrounds Earth.
Which is the outermost layer of the Earth?
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
