Question
Petroleum Formation
Petroleum is a fossil fuel that was formed from the remains of ancient organisms. Millions of years ago, many organisms lived in shallow seas. These organisms eventually died and sank to the seafloor where they became buried in layers of sediment. After millions of years under high pressure and high temperature, the remains of these organisms transformed into fossil fuels, including petroleum. Today, petroleum is found underground and then removed with giant drilling machines. The pictures show how petroleum was formed.
The left picture shows an ocean 300 to 400 million years ago. The ocean has fish, starfish, plants, corals, and rocks. The middle picture shows an ocean 50 to 100 million years ago. The ocean has fish, plants, corals, rocks, a layer of sand and silt, and a layer of plant and animal remains. The right picture shows a present-day ocean. An oil drill sits on a layer of sediment and rock, which sits on top of oil deposits. The oil drill is shown drilling into the oil deposits.
The picture shows where petroleum can be found on Earth.
The map shows that the regions of major petroleum deposits are mostly along the coasts of North America, South America, Europe, Africa, Asia, and Australia. Some petroleum deposits are found more inland in North America, Europe, and Asia.

Answers
GPT-4o mini
The two reasons that describe why certain areas contain more petroleum are:
**B. The areas contained organic matter.**
Organic matter is essential for the formation of petroleum, as it comes from the remains of ancient organisms that are transformed into fossil fuels over time.
**A. The areas contained water.**
Access to water bodies, such as oceans, is crucial since many of the organisms that contributed to petroleum formation lived in marine environments.
So, the correct answers are **A** and **B**.
