The dark patches on the moon were once thought to be seas and are called maria (Latin for `seas`). These are not actual seas containing water but are plains formed by ancient volcanic eruptions on the lunar surface, lava.

When ancient lava reached the moon and filled its craters, it formed dark, flat plains known as lunar maria. These maria were created by volcanic activity billions of years ago and are large, smooth areas visible on the moon's surface.

What Dark relatively flat regions of the moon's surface that were formed when interior lava filled large basins are called?

Maria, also known as lunar seas, are the dark relatively flat regions of the moon's surface that were formed when interior lava filled large basins.


What does the formation of a crater follow?

There are craters formed by asteroids crashing into Earth. There are craters formed by volcanic explosions. There are craters formed by collapses in the Earth's crust.


How are craters formed on moons or planets?

Craters are formed by impacts from objects from space, such as meteorites.


How were craters formed on Phobos and Deimos?

The craters on Phobos and Deimos were formed by impacts from meteoroids and other space debris. These objects collide with the moons' surfaces at high speeds, creating craters of various sizes and shapes. Over time, the accumulation of impact events has resulted in the cratered appearance of both moons.


Why are four craters formed on the moon weekly?

Craters are formed when asteroids and comets collide with the lunar surface.


How were Uranus's craters formed?

Uranus does not have any craters. It has no solid surface.


What geological features are formed by craters as a result of impact?

Meteor craters.


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.


Why doesn't the earth have craters all over it like the moon?

The Earth has more geological activity compared to the Moon, such as plate tectonics, erosion, and volcanic activity, which constantly reshape its surface and erase crater impacts over time. The Moon has a more static surface, so craters remain visible for longer periods.


Why can you still see craters on the moon even though they were formed by ancient meteor collisions?

You can still see craters on the moon because there is no atmosphere to erode them away like on Earth. Since the moon lacks geological processes like weathering and plate tectonics, impacts from meteoroids have not been erased over time.


What is formed by meteorites?

impact craters


How are crates on the moon made?

Crates on the moon are typically made from lightweight and durable materials like aluminum or composite materials to withstand the harsh lunar environment. They are often designed to be stackable and compatible with lunar landers for easy transportation and handling on the moon's surface. Additionally, some crates may incorporate special features such as insulation or seals to protect their contents from the extreme temperatures and vacuum of space.
