The two main types of igneous rock are intrusive and extrusive. Intrusive rocks form underground and have larger crystals due to slower cooling. Extrusive rocks form on the Earth's surface and have smaller crystals due to rapid cooling.
Because there are different types of magma and different pathways for that magma to cool.
Coal and Sandstone are two types of sedimentary rocks.
The answer is implicit in your question - they are physical "objects" of different characteristics so their appearances differ. That's the first way to determine a rock's type: look it it!
Pebbles are small bits of rock. Since they can be different types of rock, they would all have different chemical formulae. There is no ONE formula for rock. Limestone is different from granite, which is different from quartz.
Different rock are made by the many different events that lead to their creation. Other rock just have different amounts and types of minerals, creating different rock with hardness, texture, color, and shape patterns.
by the way they were made or how , the 3 types of rock are igneaous,sedimentary and metamorphic.
Lava.
igneaous rok
i do not no

the different types of crystal are sugar salt and rock.
no, the eaath is made of five different types of solid rock.
No, metamorphic rock is not sedimentary; those are two different types.
Coal and Sandstone are two types of sedimentary rocks.
