Every rocks have formed in special environment some form by lava and some form in sea, raver and lakes so the rock which is formed inside water so they have fossils of specific environment and the rocks form by lava it was hot so there were no possibility to preserved living organism.
Sedimentary rocks form at the bottom of bodies of water, as more and more layers of sediment build up above them. Compared to the depths at which metamorphic rocks form, and some of the places igneous rocks form, these are indeed close to the Earth's surface.
Basaltic Magmas are dark colored, heavy and are ferromagnesian in composition, so they most times do not form light colored rocks, rather, the Felsic Granitic Magma forms the light colored rocks with lower densities.
Caves typically form in rocks that are soluble in water, such as limestone and gypsum. These rocks can be dissolved by carbonic acid in rainwater, creating cavities over time. So, caves are more likely to form in rocks that are easily eroded by water.
Metamorphic rocks form when existing rocks, such as sedimentary or igneous rocks, are subjected to high temperatures and pressures within the Earth's crust. This can occur due to tectonic activity, such as mountain-building processes, or by being buried deep within the Earth's crust.
Some fossils are not rocks, but they form because there is so much pressure and it blends

your so ugly
Generally, time. In the case of sedimentary rocks, the rocks form as sediment accumulates, then, after a long period of time, they solidify by cementation (for example calcium precipitates forming a binding matrix). The longer the time for accumulation, the thicker the sediment, and then the thicker the layer. That is a very simple answer to a complex process. Also it ignores rocks that form via volcanic forces (igneous). Metamorphic rocks are formed by heat/pressure so I'm not considering them here.
Since crack is known as rocks and rocks can be broken down, theen yes it can be broken down to its powder form but it will not be cocaine. Just repeatedly beat it until its a powder.
Intrusive rocks are igneous rocks that form when magma solidifies below the Earth's surface. They usually form by rather slow cooling, which allows time for large crystals to grow, and these large crystals tend to give them a coarse grain. Extrusive rocks are igneous rocks that form when magma solidifies above the Earth's surface. They usually form by comparatively rapid cooling, which does not allow time for large crystals to form, so they are often fine-grained or amorphous.

Its about 74 miles so it takes almost 2 hours
It is a bad idea to have small rocks in the tank so take them out and get bigger ones instead.
Stalagmites and stalactites can take thousands of years to reach just a few inches. The rate of growth for a stalagmite is based on the amount of water that is flowing through the rocks and the amount of Ca dissolved in it, but they most certainly do not grow overnight. So, no, no human could stand still long enough to have a stalagmite form on them.
Volcanic rocks form on or near Earth's surface from the solidification of magma (molten rock) that has erupted from a volcano. They can also form when lava cools and solidifies quickly in underwater environments, such as in ocean ridges or volcanic islands.
