The Oceans

Front 1

Deep-ocean Current

Back 1

Currents that form because of differences in ocean water density caused by differences in temperature and saltiness

Front 2

Surface Current

Back 2

Rivers of ocean water that flow near the surface of oceans- form when steady winds blow over the surface of the ocean

Front 3

Storm Surge

Back 3

A group of very large waves- often occur during hurricanes and cause a lot of damage

Front 4

Wave

Back 4

The up and down movement of the water particles that make it up

Front 5

Evaporation

Back 5

Process of a liquid turning into a gas when it is warmed

Front 6

Condensation

Back 6

Process of a gas turning into a liquid when it is cooled

Front 7

Precipitation

Back 7

Water drops that fall to Earth as rain, snow, sleet, or hail

Front 8

Water Cycle

Back 8

The constant recycling of water from Earth's surface, to the atmosphere, and back to the Earth's surface again (evaporation, condensation, and precipitation)

Front 9

Tide

Back 9

Daily change in the local water level of the ocean- caused mainly by the gravitational pull of the moon on Earth's oceans

Front 10

Trench

Back 10

A very deep opening in the ocean floor

Front 11

Adyssal Plain

Back 11

A vast flat area of ocean floor covered with thick layers of sediment

Front 12

Continental Shelf

Back 12

The ocean floor of the shore zone

Front 13

Shore Zone

Back 13

Place where land and ocean meet

Front 14

Mid-ocean Ridge

Back 14

A series of mountain ranges that are found in the middle section of the Earth's oceans
