When molten rock undergoes crystallization above ground, what type of rock results?
a. intrusive igneous rock
b. extrusive igneous rock
c. metamorphic rock
d. sedimentary rock

Answer;

-Extrusive igneous rock

When molten rock undergoes crystallization above ground, it results to an extrusive rock.

Explanation;

-Crystallization is one of the three processes that change one rock to another in the rock cycle, other are; metamorphism, and erosion and sedimentation.

-Igneous rocks are rocks formed from the crystallization of a liquid (molten rock). Igneous rocks may be divided into two categories. Intrusive or plutonic rocks crystallize from magma beneath the earth's surface.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

because the light is a great source of energy for the plants to survive. (i hope this )
