Explanation:

Rhyolite is an extrusive (volcanic) igneous rock, formed from lava that cools quickly at the Earth's surface, resulting in fine - grained texture. Granite is an intrusive igneous rock, formed from magma that cools slowly beneath the Earth's surface, resulting in coarse - grained texture. So the first blank should be "Extrusive (Volcanic) Igneous" and the second blank should be "Intrusive (Plutonic) Igneous".

Answer:

First blank: Extrusive (Volcanic) Igneous
Second blank: Intrusive (Plutonic) Igneous
