your so ugly
All rock does not contain mineral crystals. Obsidian, or volcanic glass, in particular is a rock that has cooled so quickly from lava that mineral crystals were not able to form.
The longer that magma is able to cool, the larger the crystals will be. Intrusive rocks will have larger crystals than extrusive rocks. For example granite (intrusive) has larger grains than rhyolite (extrusive).
Mostly, it depends on cooling time. If a rock cools very rapidly, a smooth texture is formed as the atoms quickly arrange themselves into a fairly smooth crystalline pattern. Think of obsidian; it cools very fast and has such small crystals looks like black warped glass. However, if a rock was formed below the Earth's surface (intrusively) like in a pluton, it will cool more slowly and will be rougher and have larger crystals.
they would use a certain tool(s) on the rocks
i don't know? hsghfhsfhsfhfh
they are able to form by how they want to form
When water is able to enter rocks, it is because they are permeable. Permeable rocks either have spaces (pores - porous rocks, e.g. sandstone), or paths through their structure (pervious rocks, e.g. limestone). These features can only be found in sedimentary/clastic rocks. Clastic means that it is made up of small particles cemented together, which gives it a grainy texture. Metamorphic and igneous rocks are crystalline, which mades them impermeable because the crystals interlock, blocking a flow of water.
Certain plants are able to get their roots into cracks in rocks. As the plant grows, the thickening roots may force the crack to widen. That, and the expanding ice in winter, may crack the rock wide open.
without them we would have no vehicles or be able to wash our teeth and our clothes.
I'm not familiar with the term "rocks pour." It's possible that it could be referring to a method of preparing certain drinks, such as cocktails, where the liquid is poured over ice cubes. If you have more context or specifics, I may be able to provide a more accurate answer.

Certain types of plants, such as lichens and mosses, can break down rocks slowly over time through a process called biological weathering. These plants release acids that can dissolve minerals in the rocks, leading to their breakdown. Additionally, certain microorganisms like bacteria and fungi also play a role in breaking down rocks through chemical processes.
