Question

3.
4. Why do the regions near the equator receive more heat​

Answer 1

Answer:

When sunlight shines on a surface, the amount of energy absorbed by the surface per unit time depends on the angle of incidence. It is maximum when the rays are perpendicular to the surface, and gets to zero when they are parallel to the surface. Consider a small portion of the earth’s surface, a little square, and the straight line perpendicular to it, the normal to the surface as we say. In the equator or near the equator it is likely to be zero degrees or close to zero, whereas near the poles it is close to 90o . Since the energy absorbed per unit area is proportional to cos θ , θ being the angle of incidence, this explains why the poles are so cold while the equator is so hot. θ depends basically on the latitude λ , is equal to λ or close to it.

Answer 2

Answer:

Because the equator is closer to the sun. ... Because the sun's rays hit the earth's surface at a higher angle at the equator.
