1. Notes on the Ocean FloorOcean Floor FeaturesWhen we look across the ocean, we see miles and miles of water. However, if we were to look under all this water, we would see many geological features that look very similar to those found on land.
2. Features of the Ocean Floor We Will Be Studying:Continental ShelfContinental SlopeContinental RiseAbyssal PlainOcean TrenchOcean Volcano
3. The ocean waters usually meet the continent at the beach.
4. Continental MarginExtension of the continent, but underwater.Includes continental shelf, continental slope, and continental rise.Ocean floor does not officially begin until the end of the continental rise.
5. Continental ShelfGradually sloping edge of the continent that reaches into the ocean. Can be thought of as the underwater section of the beach.Some continental shelves are short and some are very wide.
6. Continental Slope & Continental RiseThe continental slope is the steep slope down to the ocean floor.The continental rise is where the continent finally meets the ocean floor.
7. Abyssal PlainFlat smooth surface of the ocean floor that is made mostly of sediment from the surface of the water and runoff from the continent.Because the abyssal plain is so deep under the ocean, no sunlight gets there. It is very dark, and very cold.
8. Ocean TrenchLong, narrow (but deep) depressions in the ocean floor that are deeper than the abyssal plain.Usually happens when an oceanic plate and a continental plate collide or when two oceanic plates collide.The deepest spots on Earth are found in ocean trenches.
9. Ocean VolcanoA mountain on the ocean floor that has hot flowing magma.When the magma reaches the top of the mountain and cools, the mountain gets bigger and may form an island at the surface in the ocean.
