What factors will affect the crater size?

The factors affecting the crater size are as follows:

1, the size of the crater is determined by many factors, including the quality, speed, angle of the meteorite and the nature of the impact on the surface.

2. Meteorite quality: A meteorite with a larger mass will release more energy when it hits the surface, forming a larger impact crater.

3. Meteorite speed: When a meteorite with higher speed hits the surface, it will release more impact energy and cause a bigger impact crater.

4. Meteorite angle: A vertical impact angle usually leads to a larger impact crater, because energy is more concentrated in a smaller area.

5. The nature of the impact on the surface: the nature of the surface will also affect the formation of craters. Different types of ground have different hardness and structure, and have different responses to stress and energy transfer caused by impact. Soft surfaces are more likely to form larger craters, while hard surfaces may limit the spread of impact.

In addition, the existence of the earth's atmosphere, the inclination of the impact angle and other factors will also have a certain impact on the formation of craters. Therefore, the size of the crater is a complex problem that combines many factors, and different results may be obtained under different circumstances.

The ball was hit by meteorites many times in its development history, but some craters were eliminated or covered by geological movements such as volcanoes and weather changes such as weathering rain erosion. There are about 180 craters with good shapes, which are distributed on the earth's surface. Most of them are found in ancient and stable mainland areas with stable geology and a history of billions of years.

Friedberg crater is the largest crater with a diameter of 300 kilometers, while sudbury crater has a diameter of 250 kilometers. They are also the oldest craters, with a history of 2 billion years and 65.438+85 billion years respectively.

There is no direct relationship between the age and diameter of the crater. For example, the crater on the Yuga Peninsula in Mexico has a diameter of 180 km and an age of 65 million years. Craters with a long history like this are often eroded in a large area and can only be identified by the shape of the shock wave left on the bedrock.
