The Eath was once covered in craters. Give 2 reasons why it does not appear that way today ok? Thanks :)?

Answer 1

Lot of dirt and plants every where.

Answer 2

Well you can draw the obvious conclusion that Earth must have been hit by many, many object just by looking at the moon, the Earth is 10 times a better target than the moon. The question is: what happened to them. The main thing that has removed the craters from the Earth is the fact that the earth is still geologically active. Volcanoes, plate tectonics and other geological processes will melt and reform the surface of the earth, resulting in the removal of the crater record.

The other thing that happens on earth is that craters can be eroded by water and wind, with both water and wind acting on a crater over a long time they can be eroded down to virtually nothing, although if you know what to look for you can often still find evidence of them.

Answer 3

Seismic/geological activity and erosion are why few craters are visible on Earth today.

One place where craters can still easily be spotted (using Goodle Earth) is in the North Eastern part of the Sahara desert in Egypt, Chad, Libya and the likes. In fact, there is a large impact crater field in South Western Egypt.

Answer 4

Geo-physical erosion (wind, rain, snow, ice, tectonic plate movement, volcanic activity, tidal forces, gamma rays, geological uplift.) Second, Oprah gave it a makeover. Third, how do you know the earth was once covered in craters? Fourth, Eath?

Answer 5

Don't make the mistake that there are no craters left on the Earths surface.

Answer 6

1) Wind erosion.
2) Water erosion

Answer 7

1. Most of it is covered in water.
2. The continents have shifted.

Answer 8

Trees, and water.

Answer 9

erosion and earthquakes

Answer 10

1 GEOPHYSICAL PHENOMENA
2 MAN
