What is the first layer of the atmosphere called?
Troposphere
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. We humans live in the troposphere, and nearly all weather occurs in this lowest layer.
Is the troposphere the first layer?
The troposphere (between 0 and about 15 kilometers) is the first layer above the Earth’s surface and contains approximately 85 to 90 % of the mass of the Earth’s atmosphere.
What is the troposphere known for?
The lowest portion of the atmosphere is the troposphere, a layer where temperature generally decreases with height. This layer contains most of Earth’s clouds and is the location where weather primarily occurs.
What does the term troposphere mean?
Definition of troposphere : the lowest densest part of the earth’s atmosphere in which most weather changes occur and temperature generally decreases rapidly with altitude and which extends from the earth’s surface to the bottom of the stratosphere at about 7 miles (11 kilometers) high.
Where does the troposphere start?
Earth’s surface
The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles.
Why troposphere is the most turbulent layer of the atmosphere?
The sun heats the earth that, in return heats a layer of air right above it. That air being warmer and less dense , rises. That is because, the warmer the ground, the more turbulence or thermal bubbles, as we call them.
Why is troposphere the most turbulent layer of the atmosphere?
Why the atmosphere of the troposphere is turbulent? The atmosphere of troposhpere is turbulent due to the convection currents arising from difference in heating and cooling rates between the equator and the poles.
Why is the troposphere higher at the equator?
The troposphere is thicker over the equator than the poles because the equator is warmer. Heat differential on the planet’s surface causes convection currents to flow from the equator to the poles. This implies that the warmer the weather, the thicker is the troposphere.
What is the another name of troposphere?

What occurs in the troposphere?
The troposphere is the lowest layer of Earth’s atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
What layer of the atmosphere is the troposphere?
The troposphere is the lowest layer of Earth’s atmosphere, and is also where nearly all weather conditions take place.
What layer of the atmosphere does weather occur?
Most types of clouds are found in the troposphere, and almost all weather occurs within this layer. The troposphere is by far the wettest layer of the atmosphere; all of the layers above contain very little moisture. The bottom of the troposphere is at Earth’s surface.
Where does the troposphere start and end?
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.
What is the troposphere and why is it important?
The troposphere is the first layer of the atmosphere of the Earth, and contains 75% of the mass of the planetary atmosphere, 99% of the total mass of water vapour and aerosols, and is where most weather phenomena occur.
