What are the three phases of the Moon's later history?
The Moon's later history can be divided into three main phases: the Late Heavy Bombardment, the formation of the lunar maria, and the gradual cooling and solidification of the lunar crust. During the Late Heavy Bombardment, around 4 billion years ago, the Moon experienced intense asteroid impacts that left numerous craters. Subsequently, volcanic activity led to the creation of the vast, dark basaltic plains known as the maria. Finally, the Moon's surface continued to cool and solidify, leading to its current state as a geologically inactive body.
What is a depression in the Moon's surface caused by the impact of an asteroid or meteoroid?
The usual term is crater. Most craters are nearly circular holes surrounded by rims of ejected material. The term "impact basin" is used for the multiple-ringed structures formed by large impacts.
Why does the moon have dust on it?
The moon has dust on its surface because of constant meteoroid impacts. When meteoroids collide with the moon, they create tiny particles of dust that accumulate over time. There is no atmosphere on the moon to erode the dust, so it remains on the surface.
How and when were the Maria formed on the moon?
The Maria on the Moon were formed between 3 and 4 billion years ago, primarily during the Moon's volcanic activity. They are large, dark basaltic plains created by ancient volcanic eruptions that filled large impact basins. These eruptions occurred after the heavy bombardment period when the Moon's crust had begun to cool and solidify. The resulting smooth, flat plains are less cratered than the surrounding highlands, indicating they are younger geologically.
Why cannot live on moon?
Two reasons - no air, and low gravity. Any accommodation erected on the moon would have to be air-tight, and securely anchored to the moon's surface. Additionally - it would have to be able to withstand constant bombardment by asteroids.
What contributes to the lack of evidence of the periods of heavy bombardment on earth?
Weathering, plate movements, and volcanoes destroyed many of the craters. The factors contribute to the lack of evidence of heavy bombardment of earth. This evidence was subducted or, if not subducted, weathered; since Earth was and still is a "living" planet, meaning a planet with active plate tectonics and an active hydro/atmosphere. This activity is in contrast to the Moon, where plate tectonics stopped shortly after its formation and where a hydro/atmosphere could never form. Both because the Moon was simply too small (and thus too light) to sustain plate tectonics and to keep volatiles with him/her.

What causes weathering and erosion on the moon?
Meteoroid impacts and solar wind are main causes of weathering on the moon. Erosion on the moon is primarily driven by micrometeoroid bombardment and the effects of solar radiation. The lack of atmosphere and water on the moon means that traditional weathering processes like wind and water erosion seen on Earth are absent.

Has the moon been hit by a meteoroid?
yes
What has the moon been bombarded by?
Impactors which may be asteroids or comets. The majority of these impacted the mon during the late heavy bombardment, early on in the formation of the solar system.
What are the 3 phases in which the moon evolved. List in order from youngest to oldest?

Walled what seem to be the oldest moon features?
Some of the oldest moon features are believed to be the heavily cratered highlands on the lunar surface, such as the South Pole-Aitken Basin and the cratered terrains in the southern hemisphere. These regions are thought to have formed over 4 billion years ago during a period of intense bombardment known as the Late Heavy Bombardment.
What are the oldest features on the moon called?
The oldest features on the Moon are called lunar highlands. These rugged, heavily cratered regions are composed of anorthosite and date back to the Moon's early history, around 4.4 billion years ago. The highlands are characterized by their elevation and are thought to have formed during the intense bombardment period known as the Late Heavy Bombardment. In contrast, the darker, flatter areas known as maria are younger, formed by volcanic activity.
How is it on the moon?
The moon is rocky and what caused this is meteoroid impact and of calcium,you need more info ask Neil Armstrong or a astronaut.
Where would Meteoroid space rock be?
Meteroid space rock would be at the top of the moon.
