Seafloor Topography

1. 
The deepest known point in any of the oceans is the Challenger Deep located in the Marianas Trench in the South Pacific near Guam.
  1. True
  2. False
2. 
The topography of the ocean floor is
  1. lacking any significant features
  2. less varied than that of the continents
  3. as varied as that of the continents
  4. cannot be compared to the topography of the continents
3. 
This is a 1 to 2 kilometer deep, several kilometers wide, land from which splits many segments of the oceanic-ridge crust
  1. continental shelf
  2. mid-oceanic ridge
  3. oceanic crust
  4. rift valley
4. 
This long, narrow depression is formed when the sinking tectonic plate drags the sea floor downward.
  1. island arc
  2. volcano
  3. oceanic trench
  4. rift valley
5. 
Seamounts
  1. are a special type of oceanic trench
  2. are volcanoes that form on the ocean floor
  3. form only in the Pacific ocean basin
  4. are submarine canyons found near Australia
6. 
The most prominent features of the ocean basins are the                   . They are the mountains of the deep ocean floor.
  1. continental rises
  2. hydrothermal vents
  3. ocean basins
  4. mid-ocean ridges
7. 
This hole in the deep seafloor releases hot fluid heated by magma.
  1. abyssal plain
  2. mid-ocean ridge
  3. volcano
  4. hydrothermal vent
8. 
These are large depressed crevices in the deep ocean floor.
  1. deep-sea trenches
  2. hydrothermal vents
  3. shelf break
  4. ocean crust
9. 
What are the abyssal plains?
  1. The bottom of the ocean where little light penetrates therefore there is very little life
  2. The large flat region of the open ocean floor
  3. A section of the ocean floor that rises to connect open ocean floor to continental shelf
  4. A steep incline leading down from the edge of the continental shelf
10. 
What is the continental shelf?
  1. the bottom of the ocean where little light penetrates therefore there is very little life
  2. the large flat region of the open ocean floor
  3. a gently sloping shallow area of the ocean floor that extends outward from the edge of the continent
  4. a steep incline leading down from the edge of the continental shelf
11. 
What is a guyot?
  1. a tide with the greatest difference between high and low tide when the sun and moon are aligned in a line with the earth
  2. a tide with the least difference between low and high tide that occurs when the sun and moon pull at right angles to each other
  3. a seamount with a flat top
  4. mountain ranges from each ocean connecting to form a gigantic mountain system
12. 
What is the continental rise?
  1. the bottom of the ocean where little light penetrates therefore there is very little life
  2. a section of the ocean floor that rises to connect open ocean floor to continental shelf
  3. a gently sloping shallow area of the ocean floor that extends outward from the edge of the continent
  4. a steep incline leading down from the edge of the continental shelf
