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!

thanks

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.

ok...thanks misty!!!!!

No problem!

Nope, wrong.

The slower the lava cools, the bigger the crystal rocks.
Fast cooling leads to smaller rocks.
