What is molten liquefied rock called when it irrupts from the earth's interior from a volcano or fissure and cools into a porous black and hard material?
lava
What type of rock is formed from molten lava?
When molten magma cools and crystallizes, it becomes a hard rock called igneous rock. Different magmas have different compositions and so produce different igneous rocks. If the magma cools beneath the earth's surface, it cools slowly. Rocks formed like this are called intrusive rocks, and have large crystals, e.g. granite, gabbro, dolerite. If magma comes to the surface (in a volcanic eruption) it cools rapidly. Rocks formed like this are called extrusive rocks, and they have small crystals, e.g. basalt, obsidian, pumice. Igneous rocks have interlocking mineral crystals. The crystals are arranged randomly throughout the rock. Igneous rocks are mostly non-porous.
What type of rock is hard wearing and and has large crystals?
granite
What are the two types of rocks would you find near a volcano and why?
Igneous - is found deep inside the Earth, where it's hot, it's hot enough to melt rock. After a while it cools down. As it cools it forms igneous rock. Igneous contains randomly interlocking crystals. Igneous rocks like basalt and granite non-porous and so very hard and tough. Metamorphic Rock - the temperature for metamorphic rock is hot enough to mold rock under pressure, but not enough to melt it. The difference for metamorphic rock is that the crystals are arranged in layers. That's due to the high pressure. Slate is metamorphic rock formed from shale, and marble is metamorphic rock formed from limestone.

Are crystals hard to find are they rare?
They are not rare nor are they hard to find .
Why are most metals hard?
I think it is because metals are non-porous, with more dense and compacted molecules compared with water, wood or other porous materials.

What is metallurgical coke?
when bituminous coal is heated stronly in the absence of air,the volatile matter escapes out and the mass becomes hard,strong,porous and coherent which is called Metallurgical coke.
What are rock layers?
When dirt gets into layers and then it hardens and becomes hard like a rock.
