Question: List the three major rock types that make up the earth's crust?

The Earth's crust is primarily made up of three major rock types:

1. Igneous Rocks – Formed from cooled and solidified molten rock (magma or lava). Examples include basalt and granite.

2. Sedimentary Rocks – Created by the accumulation and compression of mineral and organic particles over time. Examples include limestone and sandstone.

3. Metamorphic Rocks – Formed when existing rocks undergo intense heat and pressure, transforming their structure. Examples include marble and schist.

Each type plays a crucial role in shaping the planet’s geology and landscapes.
