Erosion, weathering
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
Because of gravity.
Mainly gravity, and air resistance.
The inner planets are different from the other planets mainly because
The largest percentage of the earths surface is covered by water mainly the Oceans (about 71%).
Plate tectonics
scoria
Earth's surface is mainly covered by water, with approximately 71% of the planet's surface covered by oceans. Landmasses, including continents and islands, make up the remaining 29% of Earth's surface.
Mars has a thin atmosphere, mainly of Carbon Dioxide. Its surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.
The process engineering is the complex and comprehensive analytical process, mainly focused on design, operation, control and optimization of all possible process especially in physical, IT or chemical industry.
Glaciers weather surface rocks mainly through the process of crushing and grinding. As glaciers move, they pick up debris and rocks of varying sizes, which then act like sandpaper against the bedrock, breaking it down into smaller particles through abrasion. Additionally, when the ice melts, the newly exposed rock surfaces are susceptible to chemical weathering processes.
Mercury has no real atmosphere, so it's a bit like the moon in that respect. Venus has a very thick atmosphere of mainly carbon dioxide, it has a huge surface pressure of around 93 bar, around 93 time that of earths. Earths atmosphere is mainly nitrogen (79%) and oxygen (20%) with some carbon dioxide (1%) roughly speaking. Mars has a thin atmosphere, mainly carbon dioxide.
