BJU Earth Science Ch 14 Review

What affects the height and time of the tides?

The longer the wavelength ...

How do ocean currents affect weather?

A flow of seawater through an area of relatively stationary water around it.

The distance between the same point on two side by side waves

Daily or twice-daily changes in the local sea level.

The two main factors that control the speed and direction of ocean surface currents

Great circling currents are called...

There are three tidal bulges on earth's surface

How does the ocean move?

The distance the wind blows over the water's surface in one direction

Some bodies of water only have one high and low tide

When waves bend as they come in at an angle and the front end slows and the back end catches up.

Ocean gyres flow in different directions depending on the hemisphere.

Because the tide schedule changes daily ________ are published so people can plan their work.

Twice daily changes in local sea level

Waves are caused mostly by

What is a turbidity current?

___________ are set in motion by winds

Waves from when something falls into the ocean, such as a piece of glacier or iceberg.

The tidal bulge on the side of the earth opposite the moon is caused by

Water being pulled from the surface into the ocean depths is called

A beach with fine sand is usually

The circular currents called gyres are caused by the Coriolis Effect.

the top of a wave is called

Ocean currents affect global weather patterns by

When the sun and moon are at right angles it causes

The transfer of mechanical energy from one place to another in water.

The shallower the water, the _________ a wave moves.

Caused by the Ekman Spiral, downwelling, or density difference - the wind is not involved.

When the beach is cut away by waves.

Caused when the earth, moon, and sun are aligned.

What do you call a mass of rock cut off from the mainland due to erosion?

Two problems caused by the Great Pacific Garbage Patch

The change of direction of water as it gets deeper relative to the surface current.

The deflection of a moving object caused by the rotation of the earth is the --

Seawater's temperature and salinity affect its

Thermohaline currents...

The Coriolis Effect causes objects to deflect to the left in the Southern Hemisphere.

The time between one wave and the next as they pass a stationary point.

Gravity driven currents that result from density differences such as salinity levels or temperature.

The movement of water from the deep abyssal areas up into low tide areas.

____________ occurs when your location moves through a tidal bulge.

Deposited sand that forms an island

These are set in motion by the winds - long-lasting features that can transport water long distances.

Tsunami waves are caused by

Fast narrow dangerous currents that flow outward from shore.
