- 1formula for measuring depth of ocean floor:2D=T*V
- 2The D in (2D=T*V) stands for:(Depth) of ocean floor
- 3The T in (2D=T*V) stands for:(Time) for signal to travel from transmitter to the receiver in seconds
- 4The V in (2D=T*V) stands for:(Velocity) or speed of sound as it travels through the ocean water
- 5What is an accretionary wedge?Built up of sediments along active continental margins
- 6Why should a swimmer caught in a rip current swim parallel with the shore?To escape the current
- 7What is a Barrier island?A broadened barrier beach, habitable in places, that provides a measure of protection for the mainland, as during hurricanes and tidal waves.
- 8Why is the moon a stronger force of tidal fluctuations than the sun?Moon is closer than the sun
- 9An _________ ________ ________ occurs along the edges of continents where plate tectonic motion is typically manifested as a convergent boundary.Active Continental Margin
- 10A narrow valley that runs parallel to the volcanic activity produced by subduction as the ocean lithosphere converges with continental lithosphereDeep Ocean Trench
- 11Which of these is a smaller scale map? Map A scale of: 1:24,000 Map B scale of : 1:500,000Map B
- 12Lines that measure latitude on the globe are called?Parallel Lines
- 13Lines that measure longitude on the globe are calledMeridian Lines
- 14A line connecting points of equal elevation? (vertical distance above mean sea level)Contour
- 15Every Fifth contour line is darker and heavier. It has a value on the line at regular intervals. this is called an?Index Contour
- 16A valley with steep sides and a flat interior that was formed by glaciers is called a?U-shaped Valley
- 17A ridge of glacier material deposited as meltwater flowed beneath a glacier in a sinuous (S-shaped) pattern is called anEster
- 18Equation for stream flow?Q = VA
- 19Q = VA ( Q represents? )Discharge
- 20Q = VA ( V represents? )Velocity
- 21Q = VA ( A represents? )Cross-Sectional (Area)
- 22When the stream leaves its banks and spreads over the floodplain, magnitude of cross sectional area (A):Goes Up
- 23When a stream leaves its banks, magnitude of Velocity (V):Goes Down
- 24What happens to the erosive (destructive) power of the stream when it spills into the floodplain?Goes Down
- 25A Mountain Peek that has been left as the result of glacial erosion and typically represents a high elevation within the map is called a :Horn
- 26A Knife-like ridge that is left as alpine glaciers erode on either side is called anArete
- 27A bowl-shaped depression carved at the head of a glacier is known as a :Cirque
