Earth Science Chapter 14 Review

The Coriolis effect affects only currents moving north and south but not east or west.

In the center of an ocean gyre, the sea level is usually________

Solar tides by themselves are much smaller than lunar tides.

the lowest part of a wave

What usually has the greatest influence in causing tides?

Stacks are very ancient coastal formations.

The Coriolis effect will not be observed in an object is _______

The very high tides that occur twice a month are caused by________

What is the most important factor adding to the existence of the Great Pacific Garbage Patch?

a point experiencing high tide

What forms of sea life take advantage of ocean currents in their efforts to move about?

Cold ocean currents along a coast can dry the air so much that a desert forms.

a wave deposit that connects an island or a stack with the mainland

The greatest number of drownings is probably caused by ________currents.

Water that is forced down by downwelling typically has _______ than surrounding waters.

the center of the earth's rotation

what combines the Coriolis effect,current speed, &water depth to produce direction of a current

The best tactic when caught in a rip current is to swim directly away from shore.

The Great Pacific Garbage Patch is an eyesore but doesn't affect the ocean environment

The wave base is the deepest depth where the passage of a wave affects the motion of particles.

a spit with a sharp bend

What is the deepest depth below the ocean's surface that is affected by a wave's passage

a higher-than-usual tide occurring twice a month

What direction should the surface currents near the Equator flow

Waves generally move water great distances.

Upwelling has been observed only near the Equator due to its lower-than-average sea level.

cold water rising to the surface

Shallow-water wave speed depends on the length of the wave.

Which of the following locations are notable for its very large tidal range?

How many tides do most coasts experience in a typical 24-hour period?

an unstable wave whose crest is falling forward

the center of revolution for the earth-moon system

There may be more than one longshore bar in the breaker zone of a beach.

Generally speaking, the longest waves have the greatest speeds.

The prevailing westerlies are winds that push surface water in a westerly direction.

The vertical distance between a wave's crest and trough is its_______

Most power plants designed to harness the power of tidal changes are fairly small.

As an ocean wave approaches the shore, ______

The moon's gravity causes the oceans to rise both on the near and the far side of the earth.

The Ekman spiral describes how a surface current changes direction and speed with latitude.

One way that coastal engineers can reduce wave erosion is to build ________

Coastal stacks are often the last remnants of _________

a point experienced low tide

Which of these is not a term that would apply to thermohaline currents

a bulge caused by the inertia of the ocean water

What current do you use to sail around the globe but stay south of Africa and South America

Which of these would have the least effect on subsurface currents?

Downwelling currents can form when too much water piles up in one place from winds or currents.

The major warm current located in the West Atlantic is the ________

a circular flow of currents within an ocean basin

a strong, narrow surface current that carries water from the shore to the sea

Currents are affected by the rotation of the earth.

Due to the Kuroshio (Japan) Current, western Canada is colder than eastern Siberia.

Which of the following factors does not directly affect the height of a wave?

Which of these is most directly related to wave speed?

the alternating rise and fall of local sea level

Which of the following is not an advantage of tidal power generation?

Cold ocean currents are responsible for many deserts around the world.

a bulge caused by the moon's gravity

Twice-daily lunar tides are not exactly 12 hours apart because the moon orbits the earth.

Deep,cold & salty currents that flow along the bottom of ocean basins are thermohaline currents

a current resulting from waves breaking at an angle to the shore
