How would a geologist identify an igneous rock as intrusive?
A.
An intrusive rock has coarse grains because it cooled more slowly on the surface of the earth.
B.
An intrusive rock has coarse grains because it cooled more slowly beneath the surface of the earth.**
C.
An intrusive rock has fine grains because it cooled more slowly beneath the surface of the earth.
D.
An intrusive rock has fine grains because it cooled more quickly beneath the surface of the earth.
idk u tell me i am wondering the same thing
WELL WE KNOW IT COOLED SLOWLY AND...
ITS EATHER coarse grains OR fine grains
I HAVE SAME QUESTION
To identify an igneous rock as intrusive, a geologist would look for certain characteristics. One important characteristic is the size of the mineral grains in the rock. Intrusive rocks have coarse grains because they cool slowly beneath the surface of the Earth.
In the given options, option B correctly describes the characteristics of an intrusive rock. It states that an intrusive rock has coarse grains because it cooled more slowly beneath the surface of the Earth. This is due to the slower cooling rate underground, allowing larger mineral grains to form.
Therefore, the correct answer is B. An intrusive rock has coarse grains because it cooled more slowly beneath the surface of the Earth.
