KS3 Geography: What are crude oil and natural gas?

Introduction to Crude Oil and Natural Gas

Crude oil and natural gas are important natural resources that we use every day. Crude oil is a thick, black liquid made up of many different chemicals. It is found deep underground and is used to produce fuels like petrol and diesel. Natural gas is a gas that is also found underground and is mainly made of methane. It is used for heating homes, cooking, and generating electricity.

Diagram A: Formation and Extraction of Oil and Gas

To understand how oil and gas are formed and extracted, look at Diagram A. Here’s how you can draw your own annotated diagram:

1. Formation: Start by illustrating layers of sedimentary rock. Explain that oil and gas are formed from ancient marine plants and animals that died millions of years ago and were buried under layers of rock.
2. Heat and Pressure: Show how heat and pressure from the layers above transform these remains into oil and gas over millions of years.
3. Extraction: Illustrate drilling rigs that are used to bring oil and gas to the surface. Label how these rigs drill through rock to reach the oil and gas reservoirs.

Products We Use Oil For

Look at Diagram C to see the different products we use oil for. Here’s a list of some common products:

• Petrol for cars
• Diesel for trucks and buses
• Heating oil for homes
• Plastics
• Chemicals
• Asphalt for roads

Personal Use of Oil

Reflect on your own life. Think about how many of these products you use daily, such as:

• Petrol in family cars
• Plastic bottles or containers
• Heating your home during winter

Comparing Photo B with Map C

Features Identification

1. Identify features 1-6 on Photo B: Look at the photo and use the map to find specific features.
2. Six-figure grid reference: Use the map to give the exact location of each feature using the six-figure grid reference system.

Camera Direction

• Direction: Think about where the camera was pointing when the photo was taken. This could be north, south, east, or west.

Describing the Oil Refinery

• Description: Look at both the map and the photo. Explain what you see in the oil refinery, including tanks, pipes, and other structures.

Location of UK Oil Refineries

• Coast Location: Consider why oil refineries are often located by the coast. This is usually for easy access to ships that bring in crude oil.

What Happens in an Oil Refinery

• Activities in the refinery: Describe what takes place in an oil refinery, including the process of turning crude oil into useful products.

Petrochemical Works Location

• Proximity to Refineries: Explain why petrochemical works are often built next to oil refineries. This is typically to use the by-products of refining oil.
