What are the large crystals called in an igneous rock mostly composed of a finer grained matrix?
The larger crystals or masses of larger crystals are called phenocrysts.
A rock with large crystals surrounded by small crystals is called?
porphyry
What are Igneous rocks that have large crystals and small crystals?
Such rocks are called porphyritic.
What is the relationship between cooling time igneous rocks and the size of its crystals?
Plutonic rocks are intrusive (they solidify before they reach the surface) and have larger crystals because the crystals have had a longer time to accumulate in the heat under the surface. Volcanic rocks are extrusive (they solidify on or near the surface) and have smaller crystals because the element has less time to accumulate when they cool quickly.

What are two types of igneous rock?
Two types of igneous rock are intrusive (also called plutonic) and extrusive. There is also porphyry rock which is partly intrusive and partly extrusive. Porphyry rock has large crystals embedded in a mass of much smaller crystals. The large crystals formed underground as does intrusive rock, and were carried in lava when it erupted. The mass of smaller crystals formed around the large crystals when the lava cooled quickly above ground, as does extrusive rock.

What is a rock called which is very hard and non porous and crystals in the layers?
Because the molecular lattice is tighter and smaller than waters molecular lattice making it impermeable
