Unpolluted air does not directly heat the Earth up. Instead, the Earth's surface absorbs sunlight and then radiates that energy back as heat. Greenhouse gases in the atmosphere trap some of this heat, creating a natural greenhouse effect that warms the planet. Unpolluted air actually helps regulate this process by allowing sunlight in and out of the atmosphere.

Why is Earth's air warm?
The sun warms the surface of the earth. This heat moves up into the atmosphere where it is absorbed by the greenhouse gases which warm up. This is how the air is warm. The warmth of the air also depends on how far from the equator you are. For example if you live in Greenland the air is generally cooler, and if you live in Hawaii or Brazil the air is generally warmer.
How does conduction increase the temperature of above earth's surface?
[hope that you mean the "air layer" just above the earth] Conduction is the way of energy transmission in solids. But when it comes to the air it is by convection & radiation. So when the solar radiations reach the earth they heat up the surrounding air molecules. Further they heat up the ground. So next the ground becomes the heat source for the air & heat energy is transmitted to the air layer just above by convection.
Air in the what is warmed by heat from the earths surface?
The air in the troposphere is warmed by heat from the Earth's surface through the process of conduction and convection. As the Earth's surface absorbs solar radiation, it heats up and transfers some of this heat to the air directly above it. This warming of the air creates temperature gradients and drives weather patterns and atmospheric circulation.
Why is air near the Earth's surface warmer?
Air near the Earth's surface is warmer because it absorbs heat from the ground, which in turn is heated by the sun. This process, called conduction, causes the air to warm up near the surface. Additionally, the Earth's surface acts as a heat source, contributing to the warmth of the air in contact with it.
Explain why earth's atmosphere is mainly heated from the ground up?
Earth's atmosphere is mainly heated from the ground up because the heat is absorbed into the ground. The warmed surface of the earth then emits heat as infrared radiation which rises into the atmosphere. There the greenhouse gases like water vapour, carbon dioxide and methane absorb and hold the heat.
What are two elements found in unpolluted air?
Two elements found in unpolluted air are nitrogen, which makes up about 78% of the atmosphere, and oxygen, which makes up about 21%. These two elements are crucial for supporting life on Earth.
Name 2 elements in unpolluted air?
Oxygen and nitrogen are two main elements found in unpolluted air. Oxygen is needed for respiration by humans and animals, while nitrogen makes up the largest portion of the Earth's atmosphere and is essential for plant growth.

How is air warmed?
The sun, originally, but the sun actually heats the earth, and warm air rises from the surface of the earth and is trapped by greenhouse gases in the atmosphere. This is mostly how the air gets warm.
Why do space vehicles heat up when they enter the earth's atmosphere?
The Space vehicles heat up when they enter the earth's atmosphere because the tendency of the air is to compress quickly when the space vehicle hits the atmosphere. When the gasses compressed the temperature also rises which causes the heat.

How does sunlight heat the air?
Sunlight heats the air by first warming the Earth's surface. The warm ground then heats the air directly above it through conduction. This warm air rises, creating pockets of warmer air that ultimately heat up the surrounding atmosphere.
This process distributes the heat from the sun around the earth?
The process that distributes the heat from the sun around the earth is called convection. As the sun heats the earth's surface, the air above it also warms up and rises. This creates a cycle where warm air rises, cools down, and then descends, helping to distribute heat around the globe.
Is heat considered air?
yes heat is considered air, its the same just warmer and moves faster, the molecules are jumping around making it hot and moving faster were cold its on slow motion
