To help you master concepts from Chapter 14 (Waves, Beaches, and Coasts), take this sample examination, though I'm sure you would rather be at the beach!

3			The distance from the crest of a wave to the next crest is: Need a Hint?
			A)	the wavelength
			B)	always the same
			C)	the wave period.
			D)	the wave speed or celerity
4			The most effective method for escaping a rip current is: Need a Hint?
			A)	catch a wave and let it carry you back to shore.
			B)	swim parallel to the shoreline.
			C)	swim against the current with all your might.
			D)	allow the current to carry you out to sea.
5			Beach sediment is typically quartz-rich sand because: Need a Hint?
			A)	other minerals are not deposited on beaches.
			B)	quartz is the only mineral that can be sand-sized.
			C)	quartz is a durable mineral that resists chemical weathering.
			D)	quartz is a mineral precipitated from seawater.
6			The movement of sediment parallel to shore when waves strike at an angle is called: Need a Hint?
			A)	longshore currents.
			B)	sediment transport.
			C)	sedimentation.
			D)	longshore drift.
7			Which of the following structures can disrupt longshore drift? Need a Hint?
			A)	jetties.
			B)	breakwaters.
			C)	marinas.
			D)	all of these.
8			What is the most common source of sand on beaches? Need a Hint?
			A)	land next to the beach.
			B)	offshore sediments.
			C)	sand transported to the beach by rivers.
			D)	dredging of sand from harbors.
9			Which landforms would you expect to find on erosional coasts? Need a Hint?
			A)	rocky headlands.
			B)	sea stacks.
			C)	sea cliffs.
			D)	all of these.
10			Which of the following would characterize a depositional coast? Need a Hint?
			A)	bay mouth bars.
			B)	spits.
			C)	deltas.
			D)	all of these.
11			A glacial valley drowned by rising sea-level is called: Need a Hint?
			A)	an estuary.
			B)	a recessional coast.
			C)	a tombolo.
			D)	a fjord.
12			The storm surge of a hurricane is caused by: Need a Hint?
			A)	high winds driving large waves ashore.
			B)	low atmospheric pressure, causing sea-level to bulge under the storm.
			C)	the movement of the hurricane onto a shoreline.
			D)	all of these
13			When waves approach a coast at an angle over a sloping seafloor, they: Need a Hint?
			A)	diffract.
			B)	break forming great surf.
			C)	refract.
			D)	none of these.
14			In shallow water, waves break because: Need a Hint?
			A)	The water gets too shallow.
			B)	they slow down.
			C)	waves become so steep that the crest topples over.
			D)	the hit the shore.
15			The maximum depth of influence of waves beneath the surface is: Need a Hint?
			A)	one-half their wavelength.
			B)	one-half their period.
			C)	one-half their frequency.
			D)	none of these.
16			As waves move into shallow water, the motion of water particles becomes: Need a Hint?
			A)	orbital.
			B)	spherical
			C)	elliptical.
			D)	mobyus.
17			The size of waves is related to: Need a Hint?

			C)	the speed of winds blowing over water.
			D)	all of these.
18			Construction of seawalls often: Need a Hint?
			A)	accelerates coastal erosion.
			B)	stops coastal erosion.
			C)	has no effect on coastal erosion.
			D)	cannot be predicted.

			A)	depositional coasts.
			B)	erosional coasts.
			C)	drowned coasts.
			D)	uplifted coasts.
