Answer to Question 1

ANS: F
The speed of sound in water changes based on water's temperature, salinity, and pressure. This can
cause depth readings from echo sounders to be inaccurate. Information can be found in the section
Understanding the Ocean Began with Voyaging for Trade and Exploration



Answer to Question 2

ANS: D
The amount of water on the planet, the clouds in the atmosphere, and technology have hindered
discovering the bathymetric studies at some point. The gravitational pull, however, has played a
helpful role in satellite calculations of the depth of the Earth. Information can be found in the section
