Walt listed the steps that occur during the formation of natural gas.Plants and animals that live in a lake die. The dead plants and animals sink to the bottom of the lake. Sand, dirt, and rocks bury the plants and animals. The dead plants and animals are exposed to extreme heat and pressure.Within about twenty years, natural gas forms.
Answer
A
Only dead plants form natural gas.
B
Land plants and animals form natural gas.
C
Natural gas only requires extreme pressure to form.
D
Natural gas takes millions of years to form.
Explanation
Natural gas forms as buried organic material is changed by heat and pressure over a very long time—usually millions of years, not about twenty years. The choice “Natural gas takes millions of years to form” is correct. The other choices either limit the source material incorrectly or say pressure alone is enough.
