The Continental Shelf __________________________.

• •Makes up about 80% of the ocean’s  surface area

• •Makes up about 8% of the ocean’s  surface area

• •Makes up about 7% of the ocean’s  surface area

• •Makes up about 12% of the ocean’s  surface area

The Continental Shelf_____________________.

• It’s the richest area of the ocean in terms of the number of species (biodiversity).

• It’s the richest area of the ocean in terms of the number of people.

• It’s the richest area of the ocean in terms of the number of ocean trenches.

The Continental Slope____________________.

• Begins at the shelf break and extends to the deep sea vent

• Begins at the shelf break and extends to the deep sea guyot

• Begins at the shelf bark and extends to the deep sea floor

• Begins at the shelf break and extends to the deep sea floor

The Continental Slope________________________

• It is much slower than the continental shelf and continental rise.

• It is much faster than the continental shelf and continental rise.

• It is much straighter than the continental shelf and continental rise.

• It is much steeper than the continental shelf and continental rise.

The Continental Rise ____________________

• is formed by whales that have been pushed down from the continental shelf and slope.

• is formed by sediments that have been pushed down from the continental shelf and slope.

• is formed by sharks that have been pushed down from the continental shelf and slope.

• is formed by sediments that have been pushed down from the continental force
