In geology, rock or stone is a naturally occurring solid aggregate of minerals and/or mineraloids.
The Earth's outer solid layer, the lithosphere, is made of rock. In general, rocks are of three types, namely igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, and petrology is an essential component of geology.
Igneous rocks are formed by heat, pressure and cooling. They can be formed inside a volcano or outside a volcano. If they are formed outside the volcano the rocks are called extrusive igneous rocks, like basalt. If it is formed inside the volcano the rocks are called intrusive igneous rocks, like granite.
They are called extrusive igneous rocks.
Intrusive igneous rocks .
Sedimentary.
rocks are formed from grains and grains are small and the rocks are big. Sedimentary rocks are formed when grains or sediments are compacted together.
Rocks cool at different rates due to how they were formed if they were formed intrusively or extrusively Examples of different igneous rocks that form differently is Granite and Gabbro form the same but different from Rhyolite.
Rocks formed from hot molten rock that has coold and hardened are called what?
those formed deep into the earth are called Intrusive or Plutonic rocks,those formed ator near thesurface are called Extrusive or volcanic rocks
Because different rocks are formed by different processes and made up of different mineral assemblages.
because the way there formed is how there different
Rocks found by volcanoes are formed from lava and magma inside and outside the volcano. Rocks found along beaches are formed all kinds of different ways. It all depends on how the rock is formed
Igneous
