All impact craters are circular, no matter what the shape of the impactor or the angle of impact.
Of the options provided in the Discussion page, only choice "B" is accurate. The energy released in the impact melted the impactor - and the surface - to the point of being fluid, or at least malleable.
Option "D", that the craters were formed early in the Moon's history, is probably also true, but the circular shape of the craters isn't dependent on this.
Circular unless hit very hard
Lunar craters are typically circular or bowl-shaped due to the impact of meteoroids hitting the surface of the Moon. The size of the crater can range from small to large, with some displaying central peaks or terraced walls. Over time, erosion and other geological processes can alter the original shape of the crater.
The curved shadow on the moon during a lunar eclipse is evidence of Earth's round shape. The Earth's shadow that falls on the moon is always curved because of the spherical shape of the Earth, which causes the shadow to appear rounded.
They may have giant stair-like terraces that are created by slumping of the walls. It can be loose materials or a blanket of debris surrounding the crater.
By the impact of meteorites. There is no atmosphere on the Moon, so no weathering to wear /erode the craters. But for the atmosphere on Earth, weathering the surface, and the activity of man, the Earth there would also be plenty of visible craters on Earth.
The shape is not a characteristic of chemical elements but is a characteristic of objects.
No, it has nothing to do with the shape of the Earth. Phases of the Moon are caused by the relative positions of the Sun, the Earth and the Moon. When seen through a telescope, Venus presents similar phases. However, the circular shape of Earth's shadow that is projected on the Moon' surface during a lunar eclipse is evidence that the Earth is round.
Craters on the moon are formed by impacts from asteroids or meteoroids. When these objects collide with the moon's surface, they create depressions that we see as craters. These craters can vary in size and shape, and they impact the lunar surface by altering its topography and composition. They also provide valuable information about the history of impacts in the solar system.
A lunar eclipse can only occur at the time of Full Moon.
Not generally, though crystal morphology can be.
The characteristic of a substance that has no definite shape but definite volume is called fluidity.
Craters are depressions in a planet's or moon's surface caused when a meteor hits the surface. On the moon craters remain undisturbed because there are no environmental forces like wind and rain to disturb resulting shape of the crater.
