Why does the earth not have an impact scarred surface like the Moon?
Why does the Moon have so many craters while Earth has so few? On Earth, impact craters are harder to recognize because of weathering and erosion of its surface. The Moon lacks water, an atmosphere, and tectonic activity, three forces that erode Earth’s surface and erase all but the most recent impacts.
Why can we see craters on the Moon even though they were formed by ancient meteor collisions?
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. Unlike the Earth, the Moon has no atmosphere to protect itself from impacting bodies. It also has very little geologic activity (like volcanoes) or weathering (from wind or rain) so craters remain intact from billions of years.
What happened to the Earth’s surface?
The surface of the earth changes. Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes.
What is the difference between a meteoroid a meteor and a meteorite?
When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.
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. All of these processes renew the surface and erase impact craters, making the surface young and relatively uncratered.
How does the Moon stabilize the Earth?
The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet’s wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.
