Want this question answered?
Rocks in stream beds can become smooth due to a process called abrasion. As water flows over the rocks, it carries sediment and particles that constantly rub against the rocks, wearing them down and making them smooth over time. The friction caused by the movement of water and sediment helps polish the surface of the rocks.
Deflation can lower the lands surface by several meters. Abrasion makes pits in rocks and produce smooth, polished surfaces.Deflation is a(n) erosion of the land by wind.Abrasion is a form of erosion that makes pit in the rocks and produce smooth, polished surfaces. (abrasion is common in some deserts and in some cold regions with strong wind).Hope this helps you !!!!! :D
If the earth had a completely smooth surface and all the components form which it was made were all evenly mixed up, then the force of gravity would be the same at all points on its surface. However the earth is not smooth , it has mountains and hollows in its surface and the rocks form which it is made are not evenly mixed, some surface rocks are heavy (dense) and some are light. This means that as compared to the theoretical smooth earth gravity field, the real earth gravity field varies from point to point over the surface. A gravity survey measures the small variations in the pull of gravity over the earth's surface and makes a map of these changes. This map helps geologists understand where the dense and light rocks are beneath the surface.
Deflation wind is when the wind blows across loose sediments and carries them away.
They may be smooth and others may be rough. Smoothness/roughness is not a defining characteristic for igneous rocks.
Most of the surface of the Moon isn't smooth at all, because of the rocks, hard soil, and many craters that dot the surface.
they are not smooth it is the sweat they produce from grinding against rocks and slopes they have scales giving them a rough texture.
It is abrasion

why are most of rocks extremely smooth

By weathering. The water currents weather the rocks leaving them smooth.
A creep
Obsidian: Its texture is glassy. Obsidian is extrusive or volcanic, because the instantaneous cooling that produces such rocks is a surface phenomenon. Obsidian is amorphous, so, unlike true rocks, it is not composed of minerals.
mica
