Final answer:
There is little evidence of the Period of Heavy Bombardment on Earth due to weathering, plate movements, and volcanic activity that have resurfaced the planet, erasing most of the impact craters over time. So the correct option is C.
Step-by-step explanation:
The question asks why there is little evidence of the Period of Heavy Bombardment on Earth. The correct answer to the question is: C. Weathering, plate movements, and volcanoes destroyed many of the craters. This is because Earth's surface is constantly being reshaped by internal forces such as plate tectonics and volcanism, which over geological timescales can erase the evidence of past impacts. Additionally, weathering processes break down and alter the landscape, including any impact craters that may have been present. In contrast to the Moon, which still has a cratered surface due to the lack of these active processes, Earth's dynamic geological activity has effectively resurfaced the planet over time, obscuring signs of the heavy bombardment period.
