How do fossils from in rocks?

Some fossils are not rocks, but they form because there is so much pressure and it blends


Why can you not find fossils in other rocks?

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.


What is meant by intrusive or extrusive rocks?

Intrusive or extrusive are terms given to igneous rocks which describe where the rock cooled and formed, since this plays an important role in the cooling time of the rock and therefore grain size of the rock. Intrusive rocks are those that cool from magma before it reaches the surface of the earth (they form inside the earth, hence the term intrusive). Extrusive rocks form by erupting or "extruding" at the surface and cooling. Intrusive rocks take a long time to cool because the surrounding rocks act as a kind of blanket and keep it warm longer, so crystals are generally large, where extrusive rocks cool quickly being exposed to air, wind, and rain, so crystals are generally small.


How the crystals inside the certain rocks are able to form?

How long did it take Mount Vesuvius to form?

An oceanic plate went underneath a continental plate and so the volcano was formed


Which type of rocks can be weathered and eroded?

All types of rocks can be eroded, so long as they are exposed to the elements.


What makes rocks thicker?

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.


Is it possible after cocaine being in its crack form for it to be brought back to its powder form and if so how is this so?

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.


Where do volcanic rocks form?

Volcano rocks come from the volcano itself because parts of the volcano might chip off inside so that will be small pieces of the volcano which are known by rocks or volcano rocks.


How are instrusive rocks different to extrusive rocks?

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.


Are sedimentary rocks made on the Earth's surface?

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.


What if your Mexican walking fish eats the rocks?

It is a bad idea to have small rocks in the tank so take them out and get bigger ones instead.
