Document Summary
If you have a coastline where water is warm and its clear, you will have coral reefs, you have and snails and other soft shell organisms. If you are in a warm or cold with river inputs you have clastic sediments, ( sand , gravel, clays, but no carbon rocks). In a map, you can see what kind of rock you have. All continents if you look at them and the depth of water, they have continental shelf. And you have lots of sediment being deposited there. Water is shallower there, nutrients coming in and fish eat. Outside the continental shelf you have the abyssal plain. In the abyssal plain you have igneous rocks underneath and sediment rock on top. Sedimentary rock on the abyssal plain would be. Because it formed at the mid ocean ridge. The dark blue line is the mid ocean ridge, the ecosystem is a little different.
