Study Notes
Characteristics of Igneous Rocks
- Igneous rocks are generally hard and difficult to break along joints.
- Over time, exposure to environmental conditions can soften them, making them easy to dig out.
- Igneous rocks can be granular or crystalline.
- The size, form, and texture of grains in igneous rocks varies significantly.
- These properties depend on the rate and location of cooling and solidification of magma/lava.
- Rapid cooling at the Earth's surface leads to rocks with little to no crystals or very small crystals.
