One way that the earth's surface changes quickly is that the earth's surface natural substances can be researched by mining or digging into the earth.
plate tectonics are one of the many slow earth change (helpers)
The earth's surface changes through erosion, due to wind, water, vegetation, ice or temperature
About one third of the land surface of the earth is desert.

The moon because no one sees when it changes.

Your question makes no sense. What substance changes from one state of matter to another (that is the first part and makes sense) at temperature and pressure experiencing earths surface? What on earth does that mean? pressure experiencing earths surface? What could it possibly mean? I really have no clue what you are trying to ask in the second part of the question. The first part however may give a clue to what you actually mean to ask. Maybe you mean "What substance changes from one state of matter to another at the temperature and pressure experienced on earths surface?" But using that as the question, there are literally hundreds or even thousands of correct answers. Here are a few Water, a liquid, changes to ice, a solid, and to steam, a gas and back to water Iodine can change from its solid form to a gas Ammonia can change from a liquid to a gas Freon can change from a liquid to a gas phosphorus can change from a solid to a gas gasoline, ether, liquid petroleum gas, naphtha, acetone, acetate all change from a liquid to a gas at atmosphere pressure at earths surface. Sodium changes from a solid to a gas. Hope this helps answer your question.
A hemisphere is one half of the sphere that makes up Earth's surface.
One third is surface and the rest is the sea.
obsidian is one of them
About 0.183g, where one g is the earths gravity, so about one fifth of the earths gravity. It is similar to our own moons surface gravity.
