Rhyolite is an igneous rock that has formed from rapidly cooling lava or ash.
No. Granite cools relatively slowly; its large crystals are one method of observing this. Granite is referred to as a "phaneritic" igneous rock, meaning that it is coarse-grained. Coarse-grained rocks cool slowly, which means that the minerals have time to form large crystals before the rock solidifies. A rock with the same composition as granite that does cool quickly is called rhyolite.
No. Intrusive igneous rocks have large crystals because they cool slowly.
When melted granite flows onto the Earth's surface and quickly hardens, it forms an igneous rock known as rhyolite. Rhyolite is fine-grained and often exhibits flow banding due to its rapid cooling process.
Granite is formed from the slow cooling of magma.
Rocks cool at different rates due to how they were formed if they were formed intrusively or extrusively Examples of different igneous rocks that form differently is Granite and Gabbro form the same but different from Rhyolite.
slowly
slowly
The thermal conductivity and color of a surface determines how quickly or slowly it will heat and cool
Neither. Foliation is a term used in assesing metamorphic rocks, not igneous rocks such as rhyolite.
I cant tell!
Igneous rocks that cool quickly on the surface are known as extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks have fine-grained textures due to their rapid cooling process.
Lava will cool quickly compared to underground magma.

im not sure but can you people help me
Most do, however some do not, for instance a pseudotachylyte cools quickly.
Andesite cools quickly because it forms from material erupted onto the surface, and so is composed to a cool environment.
