The fundamental success of ocean depth measurements taken by satellites is based on the variation of
  gravitational pull associated with bathymetric features. Indicate whether the statement is true or false.

Question 2

The continental crust has a greater percentage of continental shelves and slopes than mountains. Indicate whether the statement is true or false.

Answer to Question 1

ANS: T
Satellites measure the distance of the ocean surface from that of the satellite. Gravity pulls water
towards the sides of bathymetric features like undersea mountains. Since the water gets pulled in, it
creates a mound of water above the feature. Information can be found in the section Ocean Floor Is
Mapped by Bathymetry

Answer to Question 2

ANS: T
There are more continental shelves and slopes than there are continental mountains. This is a testament
to how much the edges of continents are submerged. The continental crust totals 29.2 and 11.4 of
that is shelves and slopes. Information can be found in the section Continental Margins May Be Active
or Passive.
