What kind of rock is pegmatite is it sedimentary igneous or metamorphic?
Pegmatite is an igneous rock that forms in the final stage of magma crystallization. It typically contains large crystals due to the slow cooling of the magma.
The melting of metamorphic or igneous rock forms what substance?
The melting of metamorphic or igneous rock forms magma, which can eventually cool and solidify to form igneous rock.
What kind of igneous rock forms near the Earth's surface?
Rhyolite is an igneous rock that forms near the Earth's surface through the rapid cooling and solidification of silica-rich magma.
What is the molten material deep inside Earth which forms igneous rock?
The molten material deep inside Earth is called magma. When magma cools and solidifies, it forms igneous rock.
What type rock forms when magma cools and hardens?
Igneous rock forms when magma cools and hardens. This type of rock can be classified as intrusive (plutonic) if it cools below the Earth's surface (slow cooling) or extrusive (volcanic) if it cools quickly on the Earth's surface. Examples of igneous rocks include granite, basalt, and obsidian.
