Question 27

How does the rotation and revolution of the Earth contribute to the occurrence of day and night?

Accepted Answer

Revolution causes the Earth to orbit on its axis, causing different parts of the Earth to receive varying amounts of sunlight, resulting in the alternation of day and night.

Answer

By inducing the Earth's magnetic field to deflect harmful solar radiation, preventing it from reaching the surface and harming living organisms.

Question 33

If there were a significant increase in incoming solar radiation reaching Earth's surface, what prediction can be made about its potential impact on ecosystems or climate?

Accepted Answer

Increased solar radiation would lead to higher temperatures, resulting in the melting of polar ice caps and rising sea levels.

Answer

Higher solar radiation levels would enhance plant growth and photosynthesis, leading to increased vegetation and biodiversity.

Answer

Excessive solar radiation would disrupt the Earth's atmospheric circulation patterns, causing less frequent and severe weather events.

Answer

Elevated solar radiation levels would deplete the ozone layer, resulting in increased ultraviolet radiation reaching the Earth's surface and harming living organisms.

Question 34
