Question:
What are the main characteristics of igneous rocks point wise in short
Answer:
Here are the main characteristics of igneous rocks:
Origin: Igneous rocks form from solidification and crystallization of molten magma or lava.
Texture: Igneous rocks have a crystalline texture due to the slow cooling of magma beneath the Earth’s surface or rapid cooling of lava on the surface.
Mineral Composition: The mineral composition of igneous rocks is determined by the chemical composition of the original magma or lava. Common minerals in igneous rocks include quartz, feldspar, mica, and pyroxene.
Color: Igneous rocks can vary in color from light-colored rocks, such as granite, to dark-colored rocks, such as basalt.
Density: Igneous rocks have a high density due to the compact nature of their crystal structure.
Classification: Igneous rocks are classified based on their mineral composition, texture, and the cooling environment. Common types of igneous rocks include granite, basalt, andesite, and obsidian.
Occurrence: Igneous rocks are found in many locations around the world and can be exposed at the Earth’s surface or buried deep beneath the surface.
