please check my answer ....plz...
the question is:
how is the size of the minerals grains affected by the rate at which molten rock materials cools?
and i think the answer is :
the bigger the grains the faster it cools.
The bigger the grains the faster it cools is right.. Good job!
i m comfused....
is it the bigger the grain the faster it cools or the bigger the grain the slower it cools.
Bigger the grain the faster it cools.. so if you had a 10 ounce piece of grain, and a 5 ounce piece of grain, the 10 ounce piece of grain would cool faster.
The slower the lava cools, the bigger the crystal rocks.
Fast cooling leads to smaller rocks.
