Question

1. why is only one side of the moon visible to earth?

tidal locking

1. list 5 surface features on the moon.

• crust
• mantile
• core
• craters
• moonquakes

1. what causes the moon to appear to change phases?

Explanation:

For Question 3:

Tidal locking occurs when the gravitational pull between Earth and the Moon slows the Moon's rotation until its rotational period matches its orbital period around Earth. This means the same side always faces our planet.

For Question 4:

Crust, mantle, and core are internal layers of the Moon, not surface features; moonquakes are geological events, not surface features. Valid surface features are distinct physical structures on the Moon's outer layer.

For Question 5:

The Moon does not produce its own light; it reflects sunlight. As the Moon orbits Earth, the relative positions of the Sun, Earth, and Moon change, altering the portion of the Moon's sunlit surface that is visible from Earth.

Answer:

1. Tidal locking
2. - Craters

• Maria (dark, flat basaltic plains)
• Highlands (lunar highlands, bright, rugged terrains)
• Rilles (long, narrow trenches or channels)
• Promontories (rocky outcrops along mare edges)

1. The changing relative positions of the Sun, Earth, and the Moon, which alter the portion of the Moon's sunlit surface visible from Earth.
