How steep are craters on the moon?
The majority of slopes steeper than 32 – 35 degrees are associated with relatively young large impact craters. Very rare extremely steep (> 45 degrees) slopes are exclusively associated with large Copernican-age craters. Craters of Early Imbrian age and older are devoid of slopes steeper than ~35 degrees.
How deep are the moons craters?
Simple craters like Moltke (which is 6.5 km in diameter and 1.3 km deep), have a smooth bowl-like shape with smooth walls. Most small craters less than about 15 km in diameter are simple craters. Complex craters like Tycho (which is 85 km in diameter and 4.5 km deep), have well defined crater rims and a central peak.
How deep is a crater?
With a depth of 1,949 feet (594 m), the lake is the deepest in the United States. In the world, it ranks ninth for maximum depth, and third for mean (average) depth….

| Water volume | 4.49 cu mi (18.7 km3) |
| Residence time | 157 years |
What are the edges of a crater called?
Rim – The edge of the crater. It is elevated above the surrounding terrain because it is composed of material pushed up at the edge during excavation. Ejecta – Rock material thrown out of the crater area during an impact event. It is distributed outward from the crater’s rim onto the planet’s surface as debris.
What is the deepest crater on Earth?
Vredefort crater
The Vredefort crater /ˈfrɪərdəfɔːrt/ is the largest verified impact crater on Earth. It was 160–300 km (99–186 mi) across when it was formed; what remains of it is in the present-day Free State province of South Africa.
What is on the dark side of the Moon?
Capturing the dark side The ‘dark side’ of the Moon refers to the hemisphere of the Moon that is facing away from the Earth. In reality it is no darker than any other part of the Moon’s surface as sunlight does in fact fall equally on all sides of the Moon.
Why are moon craters flat?
To date, impact melt in simple craters has only been observed on the Moon. The flat floor in a complex crater is typically interpreted to be the result to rebound of the crater floor and filling by debris from the wall and impact melt.
Why is crater lake so blue?
Famous for its beautiful blue color, the lake’s water comes directly from snow or rain — there are no inlets from other water sources. This means no sediment or mineral deposits are carried into the lake, helping it maintain its rich color and making it one of the cleanest and clearest lakes in the world.
Which is the deepest pit in Moon?
The South Pole–Aitken basin
The South Pole–Aitken basin is the largest, deepest and oldest basin recognized on the Moon.
How Does height affect crater depth?
The higher the ball’s starting point, the greater its velocity at impact. The greater an object’s velocity, the larger its impact crater. When dropped from a given height, the greater the mass, the larger the crater. When dropped from a given height, the greater the volume, the larger the crater.
What is the rim of a crater called?
The rim or edge of an impact crater is the part that extends above the height of the local surface, usually in a circular or elliptical pattern. In a more specific sense, the rim may refer to the circular or elliptical edge that represents the uppermost tip of this raised portion.
