| formula for measuring depth of ocean floor: | 2D=T*V |
| The D in (2D=T*V) stands for: | (Depth) of ocean floor |
| The T in (2D=T*V) stands for: | (Time) for signal to travel from transmitter to the receiver in seconds |
| The V in (2D=T*V) stands for: | (Velocity) or speed of sound as it travels through the ocean water |
| What is an accretionary wedge? | Built up of sediments along active continental margins |
| Why should a swimmer caught in a rip current swim parallel with the shore? | To escape the current |
| What 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. |
| Why is the moon a stronger force of tidal fluctuations than the sun? | Moon is closer than the sun |
| An _________ ________ ________ occurs along the edges of continents where plate tectonic motion is typically manifested as a convergent boundary. | Active Continental Margin |
| A narrow valley that runs parallel to the volcanic activity produced by subduction as the ocean lithosphere converges with continental lithosphere | Deep Ocean Trench |
| Which of these is a smaller scale map? Map A scale of: 1:24,000 Map B scale of : 1:500,000 | Map B |
| Lines that measure latitude on the globe are called? | Parallel Lines |
| Lines that measure longitude on the globe are called | Meridian Lines |
| A line connecting points of equal elevation? (vertical distance above mean sea level) | Contour |
| Every Fifth contour line is darker and heavier. It has a value on the line at regular intervals. this is called an? | Index Contour |
| A valley with steep sides and a flat interior that was formed by glaciers is called a? | U-shaped Valley |
| A ridge of glacier material deposited as meltwater flowed beneath a glacier in a sinuous (S-shaped) pattern is called an | Ester |
| Equation for stream flow? | Q = VA |
| Q = VA ( Q represents? ) | Discharge |
| Q = VA ( V represents? ) | Velocity |
| Q = VA ( A represents? ) | Cross-Sectional (Area) |
| When the stream leaves its banks and spreads over the floodplain, magnitude of cross sectional area (A): | Goes Up |
| When a stream leaves its banks, magnitude of Velocity (V): | Goes Down |
| What happens to the erosive (destructive) power of the stream when it spills into the floodplain? | Goes Down |
| A 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 |
| A Knife-like ridge that is left as alpine glaciers erode on either side is called an | Arete |
| A bowl-shaped depression carved at the head of a glacier is known as a : | Cirque |
