Is there any easy way or rhyme or something to remember rocks in jc geo?
I just made a word out of the first letter of each type: SIM
Sedimentary- compressed, sandstone, limestone.
Igneous- cooling magma/lava, different cooling rates, basalt (fast), granite (slow).
Metamorphic- change to igneous or sedimentary by heat or pressure or both (earthquake, magma forced into crust), marble (liMestone: "m" in limestone for marble).
i just did the exam questions all the time and eventually learned them :)
