What is 4 times Earth's distance from the Sun in wattsm2?
by

1 Answer

Answer :

I assume you are referring to the intensity of sunlight. This goes out from the Sun in an inverse-square law, so at 4 times the distance, you would only have 1/16 times the intensity of get on Earth. This so-called "solar constant" OUTSIDE of Earth's atmosphere, and for ALL radiation, not just visible light, is about 1361 watts per square meter, so you simply need to divide this value by 16.

How do the tilt of Earths axis and Earths movement’s around the sun cause seasons?

Description : How do the tilt of Earths axis and Earths movement’s around the sun cause seasons?

Last Answer : Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the northern hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
