Question

question 9
what has a marked impact on the amount of insolation received by different places and different times of the year?
the tilt of the earth relative to the sun
the location of the tropic of capricorn
the tilt of the sun relative to the earth
the location of the tropic of cancer

Explanation:

The tilt of the Earth relative to the Sun causes different parts of the Earth to receive varying amounts of solar radiation (insolation) at different times of the year. This tilt leads to the seasons. The Tropic of Capricorn and Tropic of Cancer are latitudes that mark the southernmost and northernmost positions where the Sun can be directly overhead, but their locations are a result of the Earth's tilt. The Sun does not tilt relative to the Earth in the relevant context for insolation variation.

Answer:

the tilt of the Earth relative to the sun
