Admin Why does the moon have more visible craters than the Earth?
Much of Earth’s surface is recycled through plate tectonic activity (and erosion), so Earth also has few craters. Why does the Moon have so many craters while Earth has so few? Essentially, the Moon’s surface has not been modified since early in its history, so most of its craters are still visible.
Why do we not see craters on Earth anymore?
In fact, most astronomers believe that the Earth was once hit by a mars-sized object, an event which created the Moon. The Earth has several very efficient erosion mechanisms which wipe away craters and other geological formations at a very rapid rate.
Why have very old craters on the moon not been erased a similar craters on Earth have been?
Why have very old craters in the moon not been erased as similar craters on earth have been? There are no erosion forces on the moon as there are on earth. 4- a solid rock crust formed over the outer surface of the moon.
Why is the moon so scarred with craters?
The Earth’s gravity is stronger than the moon’s, so it attracts more space debris than the moon does. Unlike the Earth, the moon does not have processes that remove craters from its surface. Earth has weather, water, and plants. These act together to break apart and wear down the ground.
Which craters seem the oldest?
The Yarrabubba crater in Western Australia appears to be 200 million years older than its closest challenger, the researchers write. The site was hit by a meteorite 2.229 billion years ago.
Why is Moon Full of craters but not the Earth?
The moon gets pelted by objects in the solar system, and unlike the Earth, the moon has no weather and no plate tectonics that erodes craters away. The Earth would have just as many craters but for the fact that the forces of weather and plate tectonics on Earth fills craters in and destroys them.
Why does the Moon have so many crators formed by meteoroids?
The moon’s craters are most likely the result of many asteroids and other space debris (big rocks, etc.) colliding with the moon over the past few billion years. The many craters on the moon are formed mainly because of the collision of asteroids, meteorites with the moon´s surface.
Why are meteor craters more common on the Moon than the Earth?
Meteorite crater s are more common on the Moon and Mars and on other planets and natural satellites than on Earth, because most meteorites either burn up in Earth’s atmosphere before reaching its surface or erosion soon obscures the impact site. Craters made by exploding volcanoes (e.g., Crater Lake , Oregon) are more common on Earth…
Why is the moon so big compared to Earth?
The reason for its shape is a result of its mass being great enough so that gravity pulls all of the Moon’s matter toward its center equally. Another distinct property the Moon possesses lies in its size compared to the Earth. At 3,475 km, the Moon’s diameter is over one fourth that of the Earth’s.
