Final answer:
Both Earth and the Moon have been hit by asteroids, but Earth's surface has fewer craters due to geological activity such as weathering, erosion, and plate tectonics that erase signs of impacts.
Step-by-step explanation:
Despite Earth and the Moon both having been bombarded by asteroids throughout their histories, there are comparatively few craters visible on Earth's surface. Weathering, water flow, and vegetation, in conjunction with Earth's geologically active nature, including plate tectonics, work in tandem to gradually erase these craters, unlike on the geologically inert Moon where craters persist over much longer timescales. Combined into one sentence, the student's provided information would be: Although both the Earth and Moon have been struck by asteroids over time, the Earth's active geological processes such as weather, water, and plant growth have collaboratively contributed to the fewer visible craters on its surface.
