Match the key term with the right definition

• Evaporation

• The loss of water by the plants

• Transpiration

• The water falls from the clouds in a form of rain, sleet, hail or snow.

• Infiltration

• The water is heated by the sun and it turns into water vapor

• Run-off

• Rain that is absorbed into the groun.

• Precipitation

• Rain that flows above the ground into streams and rivers.

Wind flows from an area of (a)   pressure to an area of​ (b)   ​ pressure.

The pressure differences occur when the Earth's surface is heated ​ (c)   by the Sun.

During the day, the land is ​ (d)   than the ocean . That means the air over the land

will ​ (e)  

• high
• low
• unevenly
• warmer
• rise
• evenly
• cooler

The energy from the sun is transferred to the Earth by

• Conduction

• Induction

• Radiation

• Convection

Match the following

• Prevailing Westerlies

• They are found 30 degrees latitude from the equator.

  They move from East to West

• Trade winds

• They are found at the poles, between 90 and 60 degrees latitude from the equator.

  They move from East to West

• Polar Easterlies

• They are found between 60 and 30 degrees latitude from the equator.

  They move from West to East.

1. Density currents are ​ ​​ (a)   movements of water within the ocean that result from variations in water density.

3. ​ (b)   currents are the horizontal movement of ocean water near the surface.

4. Upwelling is a phenomenon in oceanography and meteorology where deep, ​ (c)   , nutrient-rich water rises to the surface of the ocean.​ ​ ​

• vertical
• Surface
• cold
• warm
• horizontal

Upwelling can happen without winds

• Sometimes
• No
• Rarely
• Yes

A ​ (a)   is a large system of rotating ocean currents. In the Southern hemisphere, the gyres are moving ​ (b)   and in the Northern hemisphere, the gyres are moving ​ (c)   .
