What is the lowest layer called?
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.
What is lowest layer of the atmosphere?
The Troposphere
The Troposphere This is the lowest part of the atmosphere – the part we live in. It contains most of our weather – clouds, rain, snow. In this part of the atmosphere the temperature gets colder as the distance above the earth increases, by about 6.5°C per kilometre.
What is the lowest and thickest layer?
The layer closest to Earth’s surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface. The troposphere is thickest at the equator, and much thinner at the North and South Poles.
Is the stratosphere the lowest layer?
The stratosphere is a layer of Earth’s atmosphere. It is the second layer of the atmosphere as you go upward. The troposphere, the lowest layer, is right below the stratosphere. The next higher layer above the stratosphere is the mesosphere.
Which is the lowest layer of atmosphere very short answer?
Troposphere
Troposphere. The troposphere is the lowest layer in the atmosphere. It extends upward to about 10kms above sea level starting from ground level.
Which is the second lowest layer in the atmosphere?
stratosphere
The stratosphere is the second-lowest layer of Earth’s atmosphere. It lies above the troposphere and is separated from it by the tropopause.
Which is the lowest and the topmost layer of the atmosphere?
The troposphere is the lowest layer and exosphere is the highest or topmost layer.
What is the lowest layer of the atmosphere?
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.
What are the four layers of the atmosphere?
Atmosphere is usually divided into four layers called the troposphere, stratosphere, mesosphere, and the thermosphere (Fig. 6.2). 1. Troposphere : The troposphere or lower atmosphere is in contact with the earth’s surface, and is about 8 km high at the poles and 16 km at the equator.
What layer of the atmosphere is the Earth in?
The layer of the atmosphere closest to the Earth is the troposphere. It begins at the surface of the Earth and extends out to about 4 to 12 miles (6 to 20 km). This layer is known as the lower atmosphere.
