Answer 2

c. 1/2

Explanation:

• Solar radiation is not received the same everywhere at Earth's surface, due primarily to astronomical and atmospheric factors.
• At any given point of time only one half part of earth is illuminated by the Sun.

• As the moon orbits around the earth, the side facing the sun is always illuminated, just like Earth's daylight side is illuminated by the Sun.
• Land reflects 25% of sunlight, clouds reflect 50%, thus the part of earth where it is daytime and from where the Moon is visible determines how bright the earthshine on the Moon appears at any given time.
