1. Ocean Features

2. Sound Navigation and Ranging
A. SONAR

3. B. Satellites: provide great range and speed in collecting data

4. C. Echo Sounding
Shapes can be determined by measuring the time it takes for the sound to “bounce back”
Some marine life also uses this method.

5. Sonar helps us map the ocean floor

6. Features of the Ocean Floor
What is the deepest place in our oceans?
What type of plate boundary makes deep oceanic trenches?
Where is the sediment carried by rivers deposited in our oceans?
What type of plate boundary is located at mid-ocean ridges?
How does Earth’s climate effect sea levels?

7. Continental Shelf
the gently sloping edge of a continent between the shoreline and the continental slope. Generally, the water is not deeper than 200 meters. Where we swim.

8. Continental Slope
a steep slope of the ocean floor between the continental shelf and the continental rise.

9. Continental Rise
a gentle slope of the ocean floor made of sediment located between the steep continental slope and flat abyssal plain.

10. Made up of the continental shelf, slope, and rise.
Continental Margin
Made up of the continental shelf, slope, and rise.

11. An underwater volcanic mountain
Seamount
An underwater volcanic mountain

12. chains of volcanic mountains that run through the middle of the oceans
Mid Ocean Ridges
chains of volcanic mountains that run through the middle of the oceans

13. Volcanic Island
begins as a seamount and then rises above the ocean’s surface as melted rock accumulates

14. Deep Ocean Trench
the deepest places in the ocean. They form from one crustal plate subduction under another.

15. Broad, flat part of the deep-ocean basin
Abyssal Plain
Broad, flat part of the deep-ocean basin

16. Rift Valley (extra)
low valleys in the middle of mid-ocean ridges where two ocean plates are pulled apart.
