Question

multiple choice question
the annual variation in the amount of solar radiation received varies with latitude because the

sun outputs a greater amount of energy at its equator and less at its poles

protective magnetic field is weaker at the equator and stronger at higher latitudes

rotation of earth slows in summer, allowing more radiation to be received during the day
direction of earths tilt changes with respect to sun during the year

Explanation:

The Earth's tilt on its axis causes different latitudes to receive varying amounts of solar radiation throughout the year. As the Earth orbits the Sun, the tilt means that different parts of the Earth are more or less directly facing the Sun at different times, leading to seasonal changes and differences in solar - radiation amounts based on latitude. The Sun's energy output is relatively uniform, the magnetic field does not primarily affect solar - radiation amounts by latitude, and the Earth's rotation speed does not vary seasonally in a way that affects solar - radiation amounts by latitude.

Answer:

D. direction of Earth's tilt changes with respect to the Sun during the year
