What is a moon crater?

Back

A moon crater is a large, bowl-shaped depression on the surface of the Moon, formed by the impact of meteoroids, asteroids, or comets.

Front

How are craters formed on the Moon?

Back

Craters are formed when a high-speed object collides with the Moon's surface, creating an explosion that displaces material and leaves a depression.

Front

What is the largest crater on the Moon?

Back

The largest crater on the Moon is the South Pole-Aitken Basin.

Front

What are the characteristics of lunar craters?

Back

Lunar craters typically have a raised rim, a flat floor, and may contain central peaks formed by rebound after the impact.

Front

What is the difference between a simple and a complex crater?

Back

Simple craters have a bowl shape and smooth walls, while complex craters have features like central peaks and terraced walls due to larger impacts.

Front

What role does the Moon's lack of atmosphere play in crater preservation?

Back

The Moon's lack of atmosphere means there is no weathering or erosion, allowing craters to remain well-preserved for billions of years.

Front

What is the significance of studying moon craters?

Back

Studying moon craters helps scientists understand the history of the Moon, the solar system, and the processes of planetary formation.

Front

What is regolith?

Back

Regolith is a layer of loose, fragmented material covering solid bedrock on the Moon, formed by the impact of meteoroids.

Front

How do scientists date moon craters?

Back

Scientists date moon craters by analyzing the number of craters in a given area; more craters indicate an older surface.

Front

What is the difference between a lunar mare and a lunar highland?

Back

Lunar mares are dark, flat plains formed by ancient volcanic activity, while lunar highlands are lighter, more rugged areas with many craters.
