Breaking Rock Without Explosives

Pneumatic fracturing, also known as air decking, utilizes the force of compressed air to break rocks. This method involves drilling a series of closely spaced holes in the rock and then injecting high-pressure air into the holes. The sudden release of pressurized air generates stress within the rock, causing it to fracture and break apart.

3.5: The Rock Cycle

The rock cycle is usually said to begin with a hot molten liquid rock called magma or lava. Magma forms under the Earth's surface in the crust or mantle and erupts on Earth's surface as lava. When magma or lava cools, it solidifies by crystallization in which minerals grow within the magma or lava. The rock that results from this is an ...
