Question

which of the following is an important part of the reason it is hotter during summer in north america than during winter? the nights are much longer in summer, allowing temperatures to stabilize. the cloud cover over the entire surface of the earth is much less in summer. the suns rays hit the earth more directly in the summer, and spread out less. the earth is closer to the sun in summer. we see the full sun in summer, instead of one of its partial phases.

Explanation:

In summer in North - America, the tilt of the Earth's axis causes the Sun's rays to hit more directly. This means more concentrated solar energy per unit area, leading to higher temperatures. Nights are shorter in summer. Cloud cover varies and is not the main reason for the temperature difference. The Earth's distance from the Sun has a minor impact on seasonal temperature changes in a hemisphere, and we see the full Sun throughout the year, not just in summer.

Answer:

The Sun's rays hit the Earth more directly in the summer, and spread out less.
