What caused the visible scars on the Moon's surface?

• Volcanic eruptions

• Erosion by wind

• Tectonic movements

• Asteroid impacts and lava flows

Why was the far side of the Moon a mystery for so long?

• It was hidden by other celestial bodies

• It was covered by clouds

• It was always facing away from Earth

• It was too dark to see

What was surprising about the images of the Moon's far side taken by Luna 3?

• It was covered in water

• It looked completely different from the near side

• It had no craters

• It was identical to the near side

What is the main reason for the lack of lava flows on the Moon's far side?

• The far side is colder

• The far side has a thicker crust

• The far side is further from the Sun

• The far side has more craters

How much thicker is the crust on the Moon's far side compared to the near side?

• 10 miles

• 20 miles

• 40 miles

• 30 miles

What does the impact theory fail to explain about the Moon?

• The Moon's rotation

• The Moon's orbit

• The Moon's size

• The difference in crust thickness between the near and far sides

What new technology helped provide a credible explanation for the Moon's crust differences?

• Advanced telescopes

• Supercomputers

• Space probes

• Satellite imaging

According to the double moon theory, what happened to the smaller moon?

• It was destroyed by an asteroid

• It merged with the larger moon

• It drifted away into space

• It became a separate planet

What does the double moon theory suggest about the Moon's formation?

• The Moon was formed from a cloud of gas

• Two moons merged to form the current Moon

• The Moon was captured by Earth's gravity

• The Moon was formed by a single impact

What is the result of the two moons merging according to the theory?

• A perfectly smooth surface

• A thicker crust on one side

• A smaller Moon

• A uniform crust thickness
