Why is the moon’s surface cratered but Earth’s surface is not?

Why is the Moon’s surface cratered but the Earth’s is not? Earth’s impact craters have been mostly obliterated by erosion and plate tectonics. … the Moon lacks sufficient gravity to retain an atmosphere.

Why is the Moon’s surface cratered but the Earth’s is not quizlet?

Why is the Moon’s surface cratered but the Earth’s not? Earth’s impact craters have been mostly obliterated by erosion and plate tectonics. How do most astronomers today believe the Moon formed? A Mars-sized object struck the young Earth, and the ejected debris formed the Moon.

Why does the Moon have a cratered surface?

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.

Why is the Moon’s surface different from the Earth’s?

The Moon lacks an atmosphere, and the small amount of water that is present is “buried” in the polar areas. Finally, there is no life on the Moon. The major factor which does change the Moon’s surface is the impact of meteoroids, forming craters. … The surface of the Moon is very old, compared to the Earth.

Why does the Moon not have an atmosphere quizlet?

Why does the Moon not have an atmosphere? The Moon’s mass, and therefore its gravitational force, is not large enough to retain gases and volatile compounds. Therefore, any gases released on the Moon quickly escape into space.

Why doesnt the Moon have an atmosphere quizlet?

The moon doesn’t have an atmosphere because the moon has much less mass; its gravitational force is about 1/6 as strong as gravity on earth. You just studied 18 terms!

Why is the moon’s surface much more heavily cratered than Earth’s surface?

The moon’s surface is much more heavily cratered than Earth’s surface because ancient craters have already disappeared on Earth . They were worn away over time by water , wind , and other forces . Since the moon has no liquid water or atmosphere , its surface has changed very little .

Why is the moon so heavily cratered but the Earth which lives next door is not why?

The Moon is heavily cratered, but Earth which “lives next door” is NOT. Why? The average temperature on planet Earth is higher than you would expect just from the heating of sunlight alone. … In the far future, a visiting tourist from another planetary system asks to see the most massive object in our solar system.

Why is the moon so much more heavily cratered than Earth explain how crater counts tell us the age of a surface?

The fact that the Moon is much more heavily cratered than the Earth tells us that the Moon’s surface is much older. This is because the Moon is long dead geologically, except for impact cratering. Earth, however, continues to have volcanism, tectonics, and erosion.

How is the surface of the Moon similar to Earth’s surface?

Under the surface

Like the Earth, the moon boasts a crust, mantle and core. Deep inside of its interior, the moon may have a solid iron core surrounded by a softer, somewhat molten liquid iron outer core. … Earth’s moon is the second-densest moon in the solar system, beaten by Jupiter’s moon, Io.

Why does the surface of the Moon never change?

“The moon does rotate, but it rotates at the same speed that it rotates around the Earth.” The moon completes one full rotation on its axis in the time it takes to orbit the Earth. That means the same side is always turned toward us.

Why is the surface of the Moon not smooth?

Because there is no atmosphere or water on the Moon, there has been no wind, water, or ice to carve them into cliffs and sharp peaks, the way we have seen them shaped on Earth. Their smooth features are attributed to gradual erosion, mostly due to impact cratering from meteorites.

Why moon does not have an atmosphere?

The moon doesn’t have an atmosphere because the magnetic field is weak on the surface of the moon. Since the surface of the moon doesn’t absorb a measurable quantity of radiation the gas molecules are lost into space. … So that the earth has an atmosphere.

How is the Earth’s moon different from the moons of other planets?

Unlike the other big moons like Ganymede, Titan, Europa, Callisto and Triton, our Moon lacks any real atmosphere and isn’t covered in ice. Sure, it is a lot closer to the Sun, so maybe it lost much of its ice (there is some), but it is a much more desolate locale compared to the icy moons of the solar system.

How is Earth’s moon different from the moons of other planets quizlet?

It is different because the Earth has an atmosphere but the moon doesn’t. We have water and the moon does not. The moon is made out of the same material as Earth’s mantle.
