How do temperatures on earth depend on angles?

Answer 1

To the first order, each square meter of Earth sees about the same amount of sky, so its ability to bleed heat through convection and radiation is is basically a constant. However, the Sun's heat, expressed as the solar constant of about 1320 W/m^2, applies to a square meter that's perpendicular to the line of sight to the Sun. Therefore, that square meter, if tilted, receives less of the Sun's heat, and will therefore be cooler.

Answer 2

In english... The earth tilts at a 23 degree angle. During the summer solstice the north poll tilts towards the sun and because northern hemisphere is facing it, more of the suns rays reach that area. The southern hemisphere is tilted down away from the sun so it doesn't get as much sun. And during the winter solstice the earth's north poll tilts away from the sun.

Answer 3

Also, when it's summer, the sun takes a higher path in the sky, which, 1) means the sun beats straight down, as opposed to at an angle. and 2) a sun higher in the sky makes the day longer. Since the Earth warms up during the day, and cools down at night, having a longer day gives it more time to heat up while a shorter night means it has less time to cool down. in the winter, the opposite is true in that the sun doesnt take as high a path in the sky, so the days are shorter, giving the Earth less time to warm up.

Answer 4

If you make a grid that crosses perpendicular to the suns rays, every square in it will have an equal amount of the suns energy. When they hit a sphere, the angle from the sun changes, so the amount of energy per square foot changes. The energy is strongest at the center of the sphere.

Answer 5

The earth is tiped on it's axis in it's the plane of orbit about the sun. When It's North pole is tipped toward the sun at one (position or) time of the year the sun's rays strike the upper part of the globe more in line with it's plane than the lower . That causes summer in that position of earth's orbit about the sun. !80 degrees later in it's orbit the north pole is tiped away from the sun and that hemisphere now is in winter not getting the sun's ray's directly as before. In Australia they have their winter when we have our summer because the south pole is now tiped toward the sun for more direct rays and ours is tiped away.

Answer 6

Imagine heat is like a basketball. Heat come form the sun in a straight line until it hits the earth then it bounces back out into space....

Answer 7

Answer 8

it think it has something to with the way earth is tilted towards or away from the sun.
