The preserved remains or traces of a living thing .
Mention the three steps of fossil formation.
1) Plants die and settle at the bottom of a body of water.. They are buried by sediment. 2) The temperature and the pressure rise. Peat doesn’t give off a lot of heat. 3) Peat continues to be compressed and heated.
1) Many tiny sea organisms die and settle to the bottom of the ocean where they are buried by sediment. 2) Over time , the weight of both the sediment and the water above it cause the temperature and pressure to rise. 3) Eventually, all that’s left of the organism is hydrogen and carbon.
1) An animal dies and settles on the bottom of a body water. 2) Sediment buries the animal. 3) Hard parts are preserved.
Mention three examples of fossils fuels.
Sunlight, water and soil.
Coal, oil and natural gas.
Water , coal and natural gas.
What is a paleontologist?
Scientists who studies plants.
Scientists who study land.
Scientists who study fossils.
How can we learn more about an area’s history?

By studying its animals and plants.
By studying the people that live there.
It’s the age of that layer when you compare it to other layers (older, younger, or the same) .
