What is the closest atmosphere layer to the earth?

What is the closest atmosphere layer to the earth?

the troposphere
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 troposphere a layer of Earth’s atmosphere?

The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth’s surface is called the exosphere.

Is troposphere and atmosphere the same?

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 Earth is the 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 layer do planes fly in?

Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.

Why troposphere is the hottest part of the atmosphere?

D Troposphere. Hint: The earth’s atmosphere is divided into 4 main parts which are given to us. Here, the correct answer is the layer which is topmost. That layer absorbs the highest amount of solar energy making it the hottest.

What is the hottest layer in the atmosphere?

The thermosphere
The thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km.

What’s the hottest layer of Earth?

the inner core
The core is the hottest, densest part of the Earth. Although the inner core is mostly NiFe, the iron catastrophe also drove heavy siderophile elements to the center of the Earth.

What is the coldest layer in the atmosphere?

the mesosphere
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).

Which atmosphere layer is closest to the earths surface?

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).

What are the different layers of the atmosphere?

Layers of the Atmosphere 1 Troposphere. The layer of the atmosphere closest to the Earth is the troposphere. 2 Stratosphere. Above the troposphere is the stratosphere, which extends to about 31 miles (50 km) above the Earth’s surface. 3 Mesosphere. 4 Thermosphere. 5 Exosphere. 6 Pauses. 7 Ionosphere.

Why is the troposphere at the top of the atmosphere?

Thanks to its air being heated from below by the earth’s surface which absorbs the sun’s heat energy, tropospheric temperatures decrease as you travel up into the layer. At its top is a thin layer called the tropopause, which is just a buffer between the troposphere and the stratosphere.

How big is the troposphere in miles and kilometers?

The troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth.
