WHAT 3 factors affect the appearance of the impact craters?
The appearance of impact craters is influenced by several factors, including the size and velocity of the impacting object, which determine the energy released upon impact. The target surface's composition and geological properties, such as whether it is rocky, icy, or soft, also play a crucial role in shaping the crater. Additionally, the angle of impact affects the crater's morphology, with shallower angles often resulting in elongated or asymmetrical craters.
What is the origin of large craters on earth?
Large craters on Earth are often formed by the impact of meteorites or asteroids. When a large space rock collides with Earth's surface at high velocity, it creates a crater by excavating and displacing the surrounding material. The force of the impact can lead to the formation of a circular depression with distinctive features.
Why have scientists found few impact craters on Earth?
Scientists have found few impact craters on Earth because the process of erosion, tectonic activity, and volcanic activity continuously reshapes the Earth's surface, gradually erasing evidence of past impacts. Additionally, Earth's active plate tectonics often recycle or cover up old craters. Lastly, the presence of water and atmospheric activity can also contribute to the degradation of impact structures over time.
What are craters named after?
Craters on planets and moons are often named after famous scientists, artists, and explorers. On Earth, some craters are named after geographic features or towns near where they are located.
What is a definition for deep holes in the moon surface?
Deep holes on the moon's surface are often referred to as impact craters. These craters are formed when meteoroids, asteroids, or comets collide with the lunar surface, creating depressions of varying sizes and depths. These impact events have played a significant role in shaping the moon's overall topography over billions of years.
What are the dents on planets called?
The irregularly shaped indentations on planets are often called impact craters. These craters are formed when objects such as meteoroids, asteroids, or comets collide with the surface of the planet, creating depressions of various sizes.

What might be responsible for most of the craters on earth's moon?
Most of the craters on Earth's moon are believed to have been caused by impacts from meteoroids, asteroids, and comets over millions of years. These impactors have struck the moon's surface and created the circular depressions we see as craters.

The force of the impact can lead to the formation of a circular depression with distinctive features.
What are simple craters?
Simple impact craters have bowl-shaped depressions, mostly with smooth walls. This type of crater generally has a diameter less than 9 miles (15 km). Their depth is about 20% of the diameter.
Why isn't earth covered in craters?
Earth is geologically active and has moving air,water, and ice on its surface. As a result, plate tectonics and weathering largely destroy most impact craters within a few million years, and most of what is left is often buried under sediment. Craters do exist on Earth, but apart from the youngest, they are not readily apparent.

How often do craters form?
due to the striking of the meteors on moon
What are the long trails of ejecta that radiate outward from craters called?
The long trails of ejecta that radiate outward from craters are called "rays." These rays are formed when material is ejected during the impact event of a meteorite or asteroid striking a planetary surface, such as the Moon or other celestial bodies. The rays can extend for many kilometers and are often more prominent on younger craters, indicating their relatively recent formation.
How Long does Craters Last?
Craters can last for millions to billions of years, depending on various factors such as the impact's location, geological activity, and erosion processes. In space, craters on celestial bodies like the Moon or Mercury can remain relatively unchanged due to the lack of atmosphere and geological activity. On Earth, craters are often eroded or filled in over time due to weathering, tectonic activity, and vegetation, leading to a much shorter lifespan. Ultimately, the preservation of a crater is influenced by both environmental conditions and the age of the surface it resides on.
