Why would granite have larger crystals than rocks formed from lava cooled above earth surface?
Because crystals in granite had more time to form as the magma cooled slowly. Crystals that form on the surface are smaller because they cooled really quickly.

Why does Granite take much longer to form than Basalt?
hmmm, granite is intrusive, formed and cooled slowly at depth with larger individual crystals. Basalt is extrusive, fine grained (small crystals and cooled quickly. The intrusive equivalent of basalt is gabbro. For granite; rhylolite
Why would granite have larger crystals than igneous rocks formed from lava cooled above earths surface?
I think igneous rock have a larger crystal than all the others because igneous rock is all the way at the bottom of earth surface and it keeps cool of or hot at the same time.
What type of rock is formed from cooled melted rock?
Igneous rock is formed from cooled melted rock. It can be further classified as intrusive (formed below the earth's surface) or extrusive (formed on the earth's surface). Examples include granite, basalt, and obsidian.
Does granite have large mineral grains?
Granite is formed from magma that cools slowly, deep below the earth's surface. Very coarse-grained granite, called pegmatite, is formed when the magma cools extremely slowly. Most granite is hard grained
Why can two igneous rocks have the same name minerals but different names?
Although chemically equivalent, they would be different in their method of formation. Granite is an intrusive igneous rock, cooled from magma under the surface. The rock rhyolite is the chemical equivalent of granite, but formed on the surface, making it an extrusive igneous rock. Intrusive rocks have larger crystals.

Which igneous rock is cooled the slowest Gabro or Granite?
The type of igneous rock formed depends more on the composition of the magma or lava that formed it than it does on the speed at which it cooled (notable exceptions include obsidian, which is flash cooled). To determine which cooled faster look at the coarseness of the rock. Large crystalline particles are formed by slower cooling liquid since the molecules had more time to arrange into crystals. That being said, Granite is more likely than Gabbro to have cooled away from water and therefore slower.
What is granite made out of?
granite is an igneous rock and they are formed when molten rock (magma) solidifies. this rock has large crystals because it cooled slowly under the surface of the earth. Potassium-feldspar, quartz and plagioclase are the minerals that make up granite. gave you bit more background on it here, I hope it helps!
Which would have larger crystals an igneous rock formed from magma below the surface or igneous rock cooled from lava on the surface?
Crystals are generally formed when magma or molten rock cools and solidifies. Rapid cooling of the molten rock generally results in the formation of small crystals, like when magma reaches the surface. However, if they cool down slowly, then large crystals are formed. Keeping heat applied allows more growth on the crystal over time. In that logic, larger crystals grow underground.
Is all igneous rock formed from lava that cooled on Earths surface?
No, not all igneous rock is formed from lava that cooled on Earth's surface. Some igneous rocks are formed from magma that cooled below the surface, and these are called intrusive igneous rocks. These rocks cool more slowly than lava, allowing for larger mineral crystals to form.
