Injecting fluid deep into drilled oil and gas wells can create fractures in underground rocks and rock formations.

Oil and gas deposits may be trapped in spaces in these rock formations.

Injecting fluids under high pressure makes the rock fractures larger and allows trapped oil and gas to flow out of the well.

This process is called _________

STEP 1: Broccoli is machine-harvested on a farm and trucked to a food-processing factory.
