Why are there craters on the moon?
Craters on the moon are formed when objects from space, like asteroids or meteoroids, collide with its surface. The moon lacks an atmosphere to protect it, so these objects hit the surface directly, creating impact craters. Over time, these craters have accumulated, giving the moon its pockmarked appearance.
What affect does erosion have on craters?
Erosion can gradually diminish the size and appearance of craters by wearing down their rims and filling them with sediment or other materials. Over time, erosion can alter the shape and depth of craters, making them less distinguishable on the surface of the planet.
How have valleys changed?
Valleys can change over time due to natural processes like erosion from rivers or glaciers, tectonic movements, or human activities like mining or agriculture. These changes can alter the shape, size, and ecology of the valley.
Why are more craters present on the moons surface than on earths?
The moon has more visible craters on its surface compared to Earth because it lacks an atmosphere to protect it from impacting objects. Earth's atmosphere burns up most small asteroids and meteoroids before they can reach the surface, resulting in fewer visible impact craters. Additionally, the moon's lack of geological activity means that its craters remain preserved over time.
Why do craters last for millions of years on the surface of the moon?
Craters last for millions of years on the surface of the moon because the moon does not have an atmosphere. Saying this the moon does not have anything able to fill in the craters such as soil or rain.
What is the main reason that impact craters on the Moon last much longer than impact craters on earth?
Impact craters on the moon have no water/weather to erode the craters away, but on Earth the erosion erases the craters over time.
Why does mars not have many craters like mercury and the moon?
At one time Mars had a thicker atmosphere and what appears as free running fluids on its surface. Over time, these things erode away surface features such as craters.
Why are there craters on the moon?
Craters on the moon are formed when objects from space, like asteroids or meteoroids, collide with its surface. The moon lacks an atmosphere to protect it, so these objects hit the surface directly, creating impact craters. Over time, these craters have accumulated, giving the moon its pockmarked appearance.
How many craters does the Masaya volcano have?
The Masaya volcano has one main crater. However, within this main crater, there are multiple smaller craters that have formed over time.
Why are craters found on Ganymede and Callisto?
Craters are found on Ganymede and Callisto because they are both moons of Jupiter, which have been bombarded by asteroids and comets over time. These impacts have left behind craters on their surfaces, as there is no atmosphere to protect them from such collisions.
Covered with craters made by meteorites?
The surface is pockmarked with craters formed by impacts from meteorites. These craters vary in size and depth, providing a record of the history of impacts on the surface. Over time, the ongoing formation of craters shapes the landscape of the area.
What affect does erosion have on craters?
Erosion can gradually diminish the size and appearance of craters by wearing down their rims and filling them with sediment or other materials. Over time, erosion can alter the shape and depth of craters, making them less distinguishable on the surface of the planet.
When meteorites strike the moon they create?
When meteorites strike the moon, they create impact craters due to the powerful force of the collision. These craters vary in size and depth depending on the size and speed of the meteorite. Over time, the accumulation of impact craters has contributed to the rugged and cratered surface of the moon that we observe today.
Why is the earth not covered with craters?
The Earth's surface is not heavily cratered because it has active geology, erosion processes, and a dynamic atmosphere that continuously reshape the planet's surface. This actively resurfaces the Earth, erasing most impact craters over time. Additionally, Earth's strong magnetic field and thick atmosphere protect it from many smaller impacting objects.
What forms when small meteorites crash into the Moon?
When small meteorites crash into the Moon, they create impact craters. These craters can vary in size depending on the size and speed of the meteorite. Over time, the accumulation of these impact craters contributes to the Moon's rugged and cratered surface.
How does the Moon's shape change over time?
How did the dirction of the moon change over time? How did the dirction of the moon change over time?
Does Earth has craters?
yes, the earths craters were made a long time ago. Some craters are volcanos. They just pop up
