What are hydrocarbons primarily composed of?

• A mix of metals

• A mix of minerals

• A mix of hydrocarbons

• A mix of gases

How are hydrocarbons formed?

• By the cooling of lava

• Through the action of heat and pressure on ancient organic matter

• By the evaporation of water

• Through the crystallization of minerals

Where do the remains that form hydrocarbons typically accumulate?

• On ancient sea beds and lakes

• In desert sands

• On mountain tops

• In ancient forests
