Many rocks are composed of Silica and oxygen because these form 74.3% of what is on the earth's crust. The silica and other crystals form the main component of the rock structure.
somttimes crystals, sometimes (mostly) more rock
The rock with crystals inside in can be igneous rock, but no, idk about the minerals.
There is not really enough information to answer this question. What type of rock is it? Igneous or metamorphic rock (if it is a sedimentary rock and is red inside it is probably some form of iron precipitate) Does it have a crystalline structure inside the rock or not
forces inside earth
ummm volcanic rock? but really its black rock and its all over near the hawaiian volcanoes! :)
Igneous rock forms when melted rock (magma) from inside the Earth cools.
The molten rock is magma.
Since water expands when it freezes, it causes cracks in rocks when it freezes inside them.
When water freezes it expands. This process creates pressure inside of the rock, which causes it to burst open from the inside.
intrusive rock
minerals inside the rock determine the rocks composition
Oil shale rock
