Which is NOT true of submergent coastlines?
Their shorelines are dominated by erosional features
Which is NOT true of emergent coastlines?
They have very wide continental shelves.
The height of a wind-driven wave depends upon wind velocity,
duration, and fetch
A steady decrease in sea level following a high tide is called a(n)
ebb tide.
A steady increase in sea level following a low tide is called a(n)
flood tide.
Longshore currents
flow in a direction parallel to the shoreline
A longshore current will deposit sediment when
its energy decreases.
When the sun and moon are at right angles relative to Earth, they partially cancel out each other's gravitational attractions to produce a(n)
neap tide.
Backwash always flows
perpendicular to the slope of a shoreline.
When the sun and moon are aligned, their combined gravitational attractions produce a(n)
spring tide.
Which of the following is the definition of a shoreline?
the area of land between the highest and lowest possible water levels
Which of the following is most responsible for existence of tides?
the gravitational attraction of the moon
The depth equivalent to half a wavelength is a wave's
wave base
Give enough time, a sea cave is likely to erode further to become a
sea arch and then a sea stack
Record your answer from Lab Exercise #1, Question 2. What is the lowest tide that occurred on January 20, 2010?
0.9 feet
