What sources of energy reach the troposphere?

What sources of energy reach the troposphere?

As sunlight enters the atmosphere, a portion is immediately reflected back to space, but the rest penetrates the atmosphere and is absorbed by the earth’s surface. This energy is then remitted by the earth back into atmosphere as long-wave radiation.

What is the range of the troposphere?

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. At the equator it is around 11-12 miles (18-20 km) high, at 50 °N and 50 °S , 5½ miles and at the poles just under four miles high.

What happens to the energy that reaches the troposphere?

Heat at Earth’s Surface About half of the solar radiation that strikes the top of the atmosphere is filtered out before it reaches the ground. This energy can be absorbed by atmospheric gases, reflected by clouds, or scattered. The rest is absorbed by rocks, soil, and water and then radiated back into the air as heat.

What 3 Ways Can energy be transferred within the troposphere?

There are three ways heat is transferred into and through the atmosphere:

• radiation.
• conduction.
• convection.

What is an example of troposphere?

The troposphere is the lowest layer of the atmosphere with water vapor, vertical winds and temperatures that decrease as the altitude increases. An example of the troposphere is the layer below the tropopause. It is characterized by convective air movements and a large vertical temperature change. …

What is an interesting fact about the troposphere?

The air is densest in this lowest layer. In fact, the troposphere contains three-quarters of the mass of the entire atmosphere. The air here is 78% nitrogen and 21% oxygen. The last 1% is made of argon, water vapor, and carbon dioxide.

What is the role of troposphere?

MEMPHIS, TN (WMC) -The troposphere is the lowest layer of Earth’s atmosphere and the site of all-weather on Earth. Water vapor it important as it will absorb solar energy and thermal radiation from the surface of Earth, thus regulating the air temperature.

How is heat transferred into air?

Radiation is the transfer of energy between two objects by electromagnetic waves. Heat radiates from the ground into the lower atmosphere. Heat transfer by movement of heated materials is called convection. Heat that radiates from the ground initiates convection cells in the atmosphere.

What type of energy transfer does not require a medium?

by radiation
Transfer of heat by radiation does not need any material medium. Energy from the sun comes to us by radiation. 1. Heat transfer through conduction is a slow process.

What is troposphere short answer?

The troposphere is the lowest layer of Earth’s atmosphere. 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.

What are 3 important things about the troposphere?

How much of the atmosphere is in the troposphere?

The troposphere contains 75 percent of atmosphere’s mass- on an average day the weight of the molecules in the air is14.7 lb..(sq. in.)- and most of the atmosphere’s water vapor. Water vapor concentration varies from trace amounts in Polar Regions to nearly 4 percent in the tropics.

Where is water vapor greatest in the troposphere?

from the planet’s surface. The troposphere contains 99% of the water vapor in the atmosphere. vapor concentrations vary with latitudinal position(north to south). They are greatest above the tropics, where they might be as high as 3% and decrease

How is carbon dioxide related to the troposphere?

Carbon dioxide is present in small amounts, but its concentration has nearly doubled since 1900.Like water vapor, carbon dioxide is a greenhouse gas which traps some of the Earth’s heat close to the surface and prevents its release into space.

Why does the temperature go down in the troposphere?

In the troposphere, temperatures typically go down the higher you go, since most of the heat found in the troposphere is generated by the transfer of energy from Earth’s surface. The troposphere is the densest atmospheric layer, compressed by the weight of the rest of the atmosphere above it.
