What happens to heat energy that reaches Earth?

What happens to heat energy that reaches Earth?

Most of the solar radiation is absorbed by the atmosphere and much of what reaches the earth’s surface is radiated back into the atmosphere to become heat energy. Dark colored objects, such as asphalt, absorb radiant energy faster than light colored objects.

What happened to the heat energy that reaches Earth from the Sun?

The energy that reaches the Earth’s surface (primarily visible light) is absorbed by the Earth. This increases the temperature of the Earth and then that absorbed energy is released as heat.

What will happen if Earth doesn’t radiate the heat it received?

Answer: If Earth does not radiate heat Then Earth will become very hot….

How much of the sun’s energy reaches Earth?

All of the energy the sun releases does not reach Earth. One one-billionth of the Sun’s total energy output actually reaches the Earth. Of all the energy that does reach Earth, slightly less than 34 percent is reflected back to space by clouds. The Earth itself reflects another 66 percent back to space.

How much heat is radiated by the earth?

The atmosphere radiates heat equivalent to 59 percent of incoming sunlight; the surface radiates only 12 percent. In other words, most solar heating happens at the surface, while most radiative cooling happens in the atmosphere.

Can the sun power the Earth?

The sunlight that reaches Earth every day dwarfs all the planet’s other energy sources. A total of 173,000 terawatts (trillions of watts) of solar energy strikes the Earth continuously. That’s more than 10,000 times the world’s total energy use.

How does heat move through the Earth’s atmosphere?

Heat moves in the atmosphere the same way it moves through the solid Earth (Plate Tectonics chapter) or another medium. What follows is a review of the way heat flows and is transferred, but applied to the atmosphere.

How is heat energy absorbed by the ocean?

Heat absorbed by the ocean is moved from one place to another, but it doesn’t disappear. The heat energy eventually re-enters the rest of the Earth system by melting ice shelves, evaporating water, or directly reheating the atmosphere. Thus, heat energy in the ocean can warm the planet for decades after it was absorbed.

How does the Earth’s atmosphere affect the Sun?

However, since the Earth is much cooler than the Sun, its radiating energy is much weaker (long wavelength) infrared energy. We can indirectly see this energy radiate into the atmosphere as heat, rising from a hot road, creating shimmers on hot sunny days.

How is infrared energy absorbed by the Earth?

When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth’s surface. However, since the Earth is much cooler than the Sun, its radiating energy is much weaker (long wavelength) infrared energy.
