What processes happen inside the earth when making sedimentary rocks?

• weathering
• erosion
• heat and pressure

Fossil fuels form in sedimentary rock when

• sediments turn into oil.
• organic matter is squeezed by heat and pressure over time.
• rivers deposit organic matter downstream.

Fossils are best used as evidence about?

• how rocks changed over time
• how to use energy
• the plants and animals that lived a long time ago

Why are oil, natural gas and coal considered nonrenewable resources?

• they have been pressed in the earth
• they take millions of years to form
• they can be easily found

If you found this type fossil it would tell you that a large lake used to be there.
