How is coal formed?

Question

In 7th grade terms please. i have an 80 question exam tomorrow and i REALLY need to know!!!

Answer 1

Coal is called a fossil fuel because it was formed from the remains of vegetation (like trees) that grew as long as 400 million years ago. It is often referred to as "buried sunshine," because the plants which formed coal captured energy from the sun through photosynthesis to create the compounds that make up plant tissues. The most important element in the plant material is carbon, which gives coal most of its energy

Answer 2

Most coal is formed from plants like grass and trees that lived while the dinosaurs where around. As time went on the plants got covered up with more and more dirt washed down from rivers and rain which pressed it down. After it had thousands of feet of dirt and rock on it there was enough pressure to squish it into coal. Coal is mostly carbon and so are plants. To get coal you need a lot of weight and heat over millions of years to do the trick. Here's a link

Good luck !

Answer 3

Lithification is the process in which sediments compact under pressure, expel fluids that are trapped, and gradually become solid rock. Coal is a combustable rock formed from the lithification of peat. Peat is an accumulation of partially decayed vegetation matter.

So, plants die, pile up together, start to decay and form peat. The peat is burried under lots of dirt and rock until the pressure pressing down on it squezzes out all the water, then sits there until it turns into rock.

Answer 4

Coal is the remain dead plants.
