1. Notes on the Ocean Floor
Ocean Floor Features
When 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 Shelf
•Continental Slope
•Continental Rise
•Abyssal Plain
•Ocean Trench
•Ocean Volcano
4. Continental Margin
•Extension 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 Shelf
• Gradually 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 Rise
The 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 Plain
• Flat 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 Trench
• Long, 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 Volcano
• A 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.
