What happens with the heat or energy Earth receives from the sun quizlet?
Energy from the Sun is transferred to Earth through convection. Radiation requires a heated liquid to transfer energy. Nearly all of the energy that Earth receives from the Sun is used in photosynthesis. In the atmosphere water vapor condenses to form clouds.
What happens to the energy we receive from the sun?
The Sun’s energy gets to the Earth through radiation, which you can prove just by standing outside and letting the sun’s rays warm your face on a sunny day. The energy lost is emitted as light or electromagnetic radiation. Energy that is absorbed by an atom causes its electrons to “jump” up to higher energy levels.
What happens after the sun heats the earth?
Answer 1: The sun heats the earth through radiation. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
What happens to solar energy when it reaches Earth?
About 30% of the solar energy that reaches Earth is reflected back into space. The rest is absorbed into Earth’s atmosphere. The radiation warms the Earth’s surface, and the surface radiates some of the energy back out in the form of infrared waves.
How much sunlight falls on the earth?
In terms of energy, sunlight at Earth’s surface is around 52 to 55 percent infrared (above 700 nm), 42 to 43 percent visible (400 to 700 nm), and 3 to 5 percent ultraviolet (below 400 nm).
