What changes buried organic matter into fossil fuels?

A student creates a model of the formation of fossil fuels by first placing a layer of leaves, representing organic matter, in the bottom of a cup. What step will come next in the model?

A solid fossil fuel that is formed from the remains of plants over very long periods of time

A natural, nonrenewable fuel such as coal, oil, or natural gas formed a very long time ago from the remains of living organisms

A nonrenewable natural resource produced from the remains of organisms buried under layers of sediments for millions of years

The waste and remains of plants and animals

Force of objects pushing on other objects

Rock formed when particles of other rocks are deposited in layers and are compacted (crushed together) and cemented (binding of the sediments)

Tiny pieces of rock

Particles are squeezed together by the weight of layers of sediment above them is called -
