So I'm learning in a class that coal is made when land plants (in swamps) die and then get buried in sediments, and with the Earth's pressure/temperature the plants become coal.
Then I learned that when ocean plants (like algae and plankton) die, they also get buried in sediments in the sea floor, and with temperature/pressure they become oil.
Why don't the ocean plants become coal? What is the difference?
