1What is bathymetry?
- Adiscovery and study of the ocean floor contours
- Bstudy of ocean chemical composition
- Cstudy of ocean basins
- Dstudy to fin the best bath bomb
2Bathymetry started with the [blank_start]Greeks[blank_end], then technology leaped forward with the echo depth sounder in the [blank_start]1900's[blank_end].
The first comprehensive charts of the ocean floor were completed in [blank_start]1959[blank_end].- AGreeks
- BRomans
- CChinese
- D1900's
- E1800's
- F1700's
- G1959
- H1979
- I1899
- J2009
3What is used to measure ocean depth?
- Aan echo sounder
- Ba UV beamer
- Csatellites
- Dlasers
4How are satellites used in bathymetry?
- AThey measure variations in surface elevation (sea surface height).
- BThey measure variations in ocean depth (ocean floor height).
- CThey make the figures brightly colored and pretty.
- DThey provide wifi for the boats using echo sounders.
5Echo sounders send a pulse of sound every [blank_start]10[blank_end] seconds. [blank_start]121[blank_end] beams radiate from the ship's hull and cover a [blank_start]120[blank_end]-degree arc. Echo sounders provide swath coverage.
- A10
- B20
- C121
- D171
- E120
- F160
6Satellites bounce [blank_start]1000[blank_end] pulses of radar energy off the ocean surface every [blank_start]second[blank_end].
- A1000
- B100
- Csecond
- Dminute
7More than half of Earth's solid surface is at least 3,000 meters (10,000 ft) below sea level.
- AVerdadero

8What is the average depth of the ocean? Average elevation of the continents?
- A12,430 ft / 2,760 ft
- B2,760 ft / 2,760 ft
- C3,546 ft / 1,670 ft
- D10,430 ft / 1,760 ft
9[blank_start]Continental Margins[blank_end]: the submerged outer edge of a continent
