Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific discipline?Petroleum geology and geophysics
2. What is the primary geophysical method?Seismic exploration (3D/4D imaging)
3. What are hydrocarbons and why do we look for them underground?Hydrocarbons are natural fuels like oil and gas that power many things. We search underground to find places where they are stored so we can use them safely.
4. How do scientists find oil and gas without digging first?They use special tools that send sound waves into the ground and listen for echoes. The echoes help them see hidden layers and spots that might hold oil or gas.

Sedimentary Basins: Large depressions in the Earth's crust where sediments accumulate, often containing hydrocarbons.
Reservoir Rock: Porous and permeable rock that can hold significant quantities of oil or natural gas.
Seismic Waves: Vibrations that travel through the Earth, used in exploration to map subsurface structures.
Petrochemical Industry: Industries that produce chemicals derived from petroleum or natural gas.
