Unit 8-oceans vocab

Question 1

Air pressure

Answer 1

Force per unit area exerted on a surface by the weight of air above that surface in the atmosphere of earth

Question 2

Coriolis effect

Answer 2

The apparent curving of the path of a moving object from an otherwise straight path due to earths rotation

Question 3

Global winds

Answer 3

The movement of air over earths surface in pattern that are worldwide

Question 4

Wind

Answer 4

The movement of air caused by differences in air pressure

Question 5

Jet stream

Answer 5

Narrow belt of high speed wind that blows from west to east above earths surface

Question 6

Local wind

Answer 6

Movement of air over short distances

Question 7

Ocean currents

Answer 7

Streamlike movement of water

Question 8

Surface currents

Answer 8

Ocean currents that occur at or near the surface of the ocean and are caused by wind

Question 9

Deep currents

Answer 9

Movements of ocean water far below the surface and are called are caused by differences in density

Question 10

Convection

Answer 10

Movement of matter (water and air) due to differences in density

Question 11

Convection current

Answer 11

Movement of water that results from density differences

Question 12

Upwelling

Answer 12

The process in which winds cause warm surface currents to move away from the shore and a warm surface water is then replaced by cold nutrient rich water from the deep ocean

Question 13

Density

Answer 13

The amount of matter in a given space

Question 14

Salinity

Answer 14

A measure of the amount of dissolved salts or solid in a liquid

Question 15

Continental deflection

Answer 15

When the surface currents meet continents causing the current of water to change direction

Question 16

Evaporation

Answer 16

When a liquid is heated and changes to a gas this causes ocean salinity to increase

Question 17

Seabreeze

Answer 17

During the day a local wind that blows cooler more dense air from water onto the land

Question 18

Land breeze

Answer 18

During the night, a local wind that blows cooler, more dense air from the land towards the water

Question 19

Valley breeze

Answer 19

A local wind during the day, the sun warms the air along the mountain slopes faster then it does the air in the valley

Question 20

Mountain breeze

Answer 20

A local wind that at night, the air along the mountain slopes cools and moves down into the valley
