Very early on in Earth's history as the planetary bodies were forming from the dust ring round the new Sun, approximately 4.5 billion years ago.

It is believed that it was formed from the "splash" material thrown out when the young Earth had a collision with another planet, a Mars-sized body called Theia.

What is the name for a trench on the moon?

A trench on the moon is referred to as a "rille." Rilles are long, narrow depressions on the lunar surface that can stretch for hundreds of kilometers. They are thought to have been formed by a combination of volcanic activity, tectonic forces, and impacts from space debris.


How were craters on the moon formed?

Craters on the moon were mostly formed by impacts from meteoroids and asteroids colliding with the moon's surface. When these objects traveling at high speeds hit the moon, they create craters by excavating material from the lunar surface. Some craters may also have been caused by volcanic activity early in the moon's history.


For how long has the moon been here?

The moon formed from the debris resulting from the impact of a Mars sized body with the nascent earth, a little more than 4.5 billion years ago. The moon would have formed quickly, within just a thousand years of that impact, and less than half the distance at which it currently is.


What are the deep narrow valleys on the moon called?

The deep narrow valleys on the Moon are called rilles. These are long, winding depressions that can stretch for many kilometers across the lunar surface. Rilles are thought to have been formed by a combination of ancient volcanic activity and tectonic forces.


What are the maria on the surface on the moon?

The maria are large, dark, flat areas on the surface of the moon that were formed by ancient volcanic activity. They are primarily composed of basaltic rock and are thought to have been created billions of years ago when lava flowed and filled in large impact craters on the moon.

How do scientist think your moon was formed?

The moon was thought to have formed 4.527 billion years ago, when a large planetoid the size of mars collided with the earth, as the solar system was still in its infancy. The remains of this impact went into orbit around the Earth, forming into the moon we have today.

Did erosion create a lot of valleys on the surface of the moon?

Valleys on the surface of the moon are mainly thought to have been formed by ancient tectonic and volcanic processes rather than erosion. While some erosion due to micrometeoroid impacts may have occurred, it is not considered the primary mechanism for valley formation on the moon.

What are cigar shaped depressions on the moon called?

Cigar-shaped depressions on the Moon are called "rilles." They are long, deep channels that are thought to have been formed by volcanic activity or the collapsing of underground lava tunnels. Rilles can be several kilometers wide and hundreds of kilometers long.
