Chapter 16 The Dynamic Ocean Earth Science

Which is created in the process of erosion?

The energy and motion of most waves is derived from

Surface currents are movements of water that flow ___________ in the upper part of the ocean’s surface.

Due to Earth’s rotation, currents are deflected to the left in the N. Hemisphere & to the right in the S. Hemisphere.

______________ pattern has two high tides and two low tides each tidal day.

The structuresthat are used to protect a coast from erosion or to prevent the movement of sand along a beach.(morethan1)

What does C represent ?

Downwelling is the rising of cold water from deeper layers to replace warmer surface water.

Which of the following results from refraction ?

What does A represent ?

______________ pattern has a single high tide and a single low tide each tidal day.

__________ are narrow sandbars parallel to, but separated from, the coast at distances from 3 to 30 kilometers offshore.

A ____________ is a current that flows parallel to the shore and moves large amounts of sediment along the shore.

Because of the Coriolis Effect, surface currents in the Southern Hemisphere are deflected.

___________ is the bending of waves, and it affects the distribution of energy along the shore.

As warm water currents travel toward the equator, they help moderate the warm temperatures of adjacent land areas.

A decrease in seawater density can be caused by a increase in temperature or an increase in salinity.

Which describes a ridge of sand that connects an island to the mainland or another island?

Choose the examples of shoreline features that result from erosion: (more than one answer)

Daily changes in the elevation of the ocean surface are called

Waves along the shoreline are constantly eroding, transporting, and depositing sediment.

When currents from lowlatitude regions move into higherlatitudes they transfer heat from warmer to cooler areas on Earth

______________are huge circular-moving current systems that dominate the surfaces of the oceans.

Choose which ones that are formed as a result of deposition: (more than one answer)

Most ocean waves obtain their energy and motion from the wind.

Which term describes the rising of cold water from deeper layers to replace warmer surface water?

The five huge circular- moving systems of ocean surface currents are called

An Ocean current moving from the equator toward a pole is

____________ is the deflection of currents away from their original course as a result of Earth’s rotation.

Upwelling brings greater concentrations of dissolved nutrients, such as nitrates and phosphates to the ocean surface.

_____________ are vertical currents of ocean water that are caused by density differences among water masses.

___________ are masses of ocean water that flow from one place to another

____________develop from friction between the ocean and the wind that blows across its surface.

The movement of water within the surf zone that parallels the surf zone shore is called

________________ pattern has two high and two low tides of different heights.

The height, length,&period that are achieved by a wavedepend on 3 factors: wind speed;length of time the wind has blown&
