question 4
as you progress north or south of the equator, how does the amount of insolation received by the earths surface change?
it varies seasonally and increases in quantity toward the poles
it stays the same seasonally and increases in quantity toward the poles
it varies seasonally and decreases in quantity toward the poles
it stays the same seasonally and decreases in quantity toward the poles

Explanation:

Insolation is the solar radiation received by the Earth's surface. Due to the Earth's spherical shape and axial tilt, the amount of insolation varies seasonally. Near the Equator, the Sun's rays are more direct, providing more insolation. As one moves towards the poles, the Sun's rays become more oblique (less direct), spreading the same amount of solar energy over a larger area, thus decreasing the insolation. Seasonal variation occurs because of the Earth's orbit and tilt, causing different hemispheres to receive more or less direct sunlight at different times of the year.

Answer:

it varies seasonally and decreases in quantity toward the poles
