Properties and Types of Rocks

Igneous rock is formed from the cooling and solidification of magma or lava.

You are testing the streak of the rock, which is the color of the powder left behind.

Texture is not considered a property of minerals; the main properties include streak, hardness, and color.

Metamorphic rock is formed from existing rocks that change due to heat and pressure.

It means the rock was formed from lava that erupted onto Earth's surface.

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Hardness is a measure of how resistant a rock is to being scratched.

Magma is molten rock beneath the Earth's surface, while lava is magma that has erupted onto the surface.

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and crystalline structure.

The streak test is used to determine the color of a mineral in powdered form.
