What are the classifications of the atmosphere?

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.

What are the different temperatures of the atmosphere?

Temperature of atmosphere:

The Earth’s temperature range in Fahrenheit is from 2,700 degrees Fahrenheit (1,500 degrees Celsius) in the uppermost atmosphere to a global average temperature of around 59 degrees Fahrenheit (15 degrees Celsius) near the surface.

What are the 7 atmosphere layers?

Layers of Earth’s Atmosphere
  • Troposphere. The troposphere is the lowest layer of our atmosphere. …
  • Stratosphere. The next layer up is called the stratosphere. …
  • Mesosphere. Above the stratosphere is the mesosphere. …
  • Thermosphere. The layer of very rare air above the mesosphere is called the thermosphere. …
  • Exosphere. …
  • Ionosphere.

What determines the temperature of a layer of the atmosphere?

heat source
A change in temperature with distance is called a temperature gradient. The Earth’s atmosphere is divided into layers based on the layer’s temperature gradient, and the heat source of the layer determines the temperature gradient in each layer.

What are the four layers of the atmosphere based on temperature?

The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere.

What do you mean by atmospheric temperature?

Atmospheric temperature is a measure of temperature at different levels of the Earth’s atmosphere. It is governed by many factors, including incoming solar radiation, humidity and altitude.

What is the temperature of the stratosphere?

In this region the temperature increases with height. Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere.

Which layer of the atmosphere has the lowest temperature?

Mesosphere
Mesosphere, altitude and temperature characteristics

The top of the mesosphere is the coldest area of the Earth’s atmosphere because temperature may locally decrease to as low as 100 K (-173°C).

What is the temperature of the exosphere?

The temperature (or average kinetic energy) within particles of air in the exosphere are as hot as 987.5 degrees Celsius.

How is temperature different in each layer of the atmosphere?

The temperature of the atmosphere in the troposphere decreases with altitude. The air in the troposphere is denser at lower levels of the layer and thinner at higher levels in the layer. This is largely responsible for the decrease in temperature seen in the troposphere.

What is the hottest layer of 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. Temperatures can reach as high as 2000 K or 1727 ÂșC in this layer (Wallace and Hobbs 24).

What is the coldest layer of the atmosphere?

The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere. The coldest temperatures in Earth’s atmosphere, about -90° C (-130° F), are found near the top of this layer.

Is warm air heavier than cold air?

What is heavier, cold air or hot air? Cold air is always heavier than an equal volume of hot air. “Air” is actually a mixture of several gases. By volume, dry air contains 78.09 percent nitrogen, 20.95 percent oxygen, 0.93 percent argon, 0.039 percent carbon dioxide and small amounts of other gases.

What layer has the most oxygen?

the troposphere
Answer and Explanation: The layer of the atmosphere that has the highest level of oxygen is the troposphere. The troposphere is the largest layer of the atmosphere that is located closest to the Earth’s surface.

What temperature is the exosphere?

The temperature (or average kinetic energy) within particles of air in the exosphere are as hot as 987.5 degrees Celsius.

What is the temperature of the stratosphere?

In this region the temperature increases with height. Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere.

Why is it called troposphere?

Closest to the surface of Earth, we have the troposphere. “Tropos” means change. This layer gets its name from the weather that is constantly changing and mixing up the gases in this part of our atmosphere.

What are the two elements of atmosphere?

We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.
