Waves, Currents and Tides

Which of the following types of water would SINK the fastest?

• warm and salty

• cold and salty

• warm and fresh

• cold and fresh

Two types of ocean currents are

• local and global
• sea and land
• surface and deep
• warm and cold

Currents that occur at or near the surface of the ocean are called 

• Deep Currents
• Convection Currents
• Surface Currents
• Wave Currents

Surface currents are mainly caused by

• The Coriolis Effect
• Cold and Warm Water
• Convection
• Wind

Warm ocean currents generally come from

• The North Pole
• The South Pole
• The Equator
• Both A and B

________ and _______ affect the ocean's density and cause the Global Conveyor Belt to travel

• gravity and the Coriolis Effect

• temperature and salinity

• wind and climate

• temperature and the Coriolis Effect

Movements of ocean water in a continuous flow are called?

• ocean currents
• global winds
• air mass
• front

What distinguishes a tsunami from other types of ocean waves?

• The wave energy of tsunamis increases as the water depth decreases.

• A tsunami forms when a large volume of water is suddenly displaced up or down.

• A tsunami is caused by the disruption of deep ocean currents by volcanic eruptions.

• The wave height of a tsunami is much lower in the center of the ocean than it is near shore.

Which statement correctly describes the motion of water particles due to the action of waves?

• They rise and fall in a circular motion.

• They travel from one crest to another.

• They move back and forth as each wave passes.

• They move in the opposite direction of the wave.

A _______ is a disturbance that transfers energy through matter.

• Salinity

• Wave

• Temperature  

• Density
