Quick Answer: How is coal formed apes quizlet?

How is coal formed apes?

Coal is formed over millions of years when partially decayed plant matter in swamps and bogs falls to the bottom and sediments cover it and over time with pressure involved the coal is formed through physical and chemical changes.

Where is coal formed quizlet?

coal is formed from dead/decayed plants that are fossilized for millions of years and is applied heat and pressure.

How do fossil fuels form apes?

Fossil fuels were formed from plants and animals that lived up to about 300 million years ago. … When the plants and animals died and started decaying, some of them got buried deep under the ground for many millions of years, where they turned into fossil fuels like coal, gas and crude oil.

How are coal deposits formed quizlet?

Present-day coal deposits formed from decomposing woody plant material which accumulated in swamps and deltas primarily during the Carboniferous Period (nearly 300 million years ago) when large regions of the Earth were covered with densely forested swamps.

What do all fossil fuels have in common?

Explanation: Hydrogen and carbon are the ingredients of all fossil fuels. They supply energy.

How are fossil fuels originally formed?

FOSSIL FUELS FORM. After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal. Today, humans extract these resources through coal mining and the drilling of oil and gas wells on land and offshore.

How are fossil fuels related to the sun quizlet?

how are fossil fuels related to the sun? All the energy in oil, gas, and coal originally came from the sun, captured through photosynthesis. In the same way that we burn wood to release energy that trees capture from the sun, we burn fossil fuels to release the energy that ancient plants captured from the sun.
