Convection and relief rainfall

What is the name for the tiny particles in the atmosphere around which condensation happens?

• Condensation nuclei

• Condensation particles

• Condensation atoms

Relief rainfall occurs when air moves towards a mountain and is forced to do what?

• Rise over it

• Go through it

• Go under it

The correct geographical term for any water falling from the sky is...

• precipitation

• accumulation

• condensation

• transpiration

Which type of rainfall is seen in the image?

• precipitation

• relief

• frontal

• convectional

Fact or Fiction?

The images illustrates convectional rainfall?

• True dat

• False as

Condensation occurs at

• saturation point temperature

• dew point temperature

• cooling point temperature

• vapour point temperature

Which type of rainfall is most likely to be found in tropical regions close to the equator?

• Convectional

• Relief

• Frontal

All rain is caused by...

• freezing and cooling
• air rising
• clouds

As air rises it cools by how much?

• 1 oC for every 100m

• 1 oC for every 1km

• 0.6 oC for every 100m

• 0.6 oC for every 1km

Condensation occurs when the temperatures reduce so that water can no longer be held in vapour form. The water condenses around condensation nuclei. When will it rain?

• straight away

• in the afternoon

• when the droplets coalesce and become too heavy

• when the air temperature drops below freezing
