Why does the Earth have fewer craters than the Moon quizlet?

Why does the Earth have fewer craters than the Moon quizlet?

There are so few craters on the Earth because most have been destroyed due to plate tectonics and erosion. There are many craters on Mercury and the Moon because neither body has an atmosphere to vaporize the meteoroid before it reaches the body’s surface.

Why are there hardly any craters on Earth?

There are two main reasons for the low number of craters. One is that our atmosphere burns up most meteoroids before they reach the surface. The other reason is that Earth’s surface is continually active and erases the marks of craters over time.

Why does the surface of the Moon have many craters?

One reason the moon has craters because it gets hit by objects, small pieces of rocks that come from outer space. These are pieces of asteroids, comets that are flying around in the solar system. When they hit the surface, there’s an impact. The moon has no atmosphere, and so even a tiny rock will create a crater.

Which of the following are reasons why the moon surface has remained mostly unchanged for 3 billion years?

Which of the following are reasons why the Moon’s surface has remained mostly unchanged for 3 billion years? The Moon does not have plate tectonics. There is no water on the Moon to cause weathering.

What is the primary reason the moon cooled quicker than the Earth?

The Moon is smaller than Earth, so the Moon contained less thermal energy in its core to begin with, and a smaller core cools faster than a larger one.

Why do temperatures vary so much on the Moon?

Why does the moon’s temperature vary so widely? It happens because the Moon doesn’t have an atmosphere like the Earth. Here on Earth, the atmosphere acts like a blanket, trapping heat. So any place on the surface of the Moon experiences about 13 days of sunlight, followed by 13 days of darkness.

Why does Earth have fewer impact craters than Mercury?

It is because earth has erosion effect due to atmosphere, raining, weather and water. There were impacts on earth by asteroids in early time of solar system formation. none of them exist now due to this erosion process.

Why are impact craters more obvious on the Moon and Mercury than on earth?

Impact craters dominate the surfaces of Mercury and the Earth’s Moon. Both bodies lack liquid water on their surfaces that would erode impact craters over time. They also lack an atmosphere which, on planets like the Earth and Venus, could disintegrate meteoroids before they impact the surface.

Why has the Moon’s surface remained unchanged?

Unlike on Earth, there is no erosion by wind or water on the moon because it has no atmosphere and all the water on the surface is frozen as ice. Also, there is no volcanic activity on the moon to change the lunar surface features. Nothing gets washed away, and nothing gets folded back inside.

Why do the features on the Moon remain unchanged?

The landscape of the Moon—its surface features—is very different from Earth. Because the Moon has no water, wind, or weather, the craters remain unchanged. The Moon’s coldest temperatures are found deep in the craters.

Why are there so many craters on Earth?

In addition to this major hit, the Earth has been struck by just as many meteorites as all the other moons and planets, and would be completely pockmarked with craters if it weren’t for one thing: erosion. The Earth has several very efficient erosion mechanisms which wipe away craters and other geological formations at a very rapid rate.

Why are there more impact craters on the far side of the Moon?

The real reason there are more impact craters on the far side of the Moon is that the near side has a much thinner crust which has allowed volcanoes to erupt and fill in ancient large basins (or large impact craters).

How many craters can you see on the Moon?

But we can see many thousands of craters on the Moon and we only know of about 180 on Earth!

Why are there fewer space rocks on the Moon than on the Earth?

The Moon may attract fewer bits of space rock than the Earth, but the Moon is powerless to do anything about it after it has been hit. Once something hits the Moon, that event becomes frozen in time.
