More about rain… and clouds

In order for rain to fall, moisture in the air needs to ​ (a)   , ​ (b)   and ​ (c)  

• rise

• cool

• condense

• evaporate

• freeze

• dissipate

• expand

Answer explanation

For rain to fall, moisture must rise to higher altitudes, where it cools down. As it cools, the moisture condenses into droplets, leading to precipitation. Thus, the correct sequence is rise, cool, and condense.

​ (a)   rainfall is formed when the ground is heated by the sun?

• Convectional

• Orographic

• Frontal

• Acidic

• Relief

Answer explanation

Convectional rainfall occurs when the sun heats the ground, causing warm air to rise. As this air cools, it condenses and forms rain. This process is distinct from orographic and frontal rainfall, which involve different mechanisms.

Reorder the following

• Precipitation occurs

• Sun heats the Earth's surface

• Warm air rises carrying moisture

• Rising air cools and condenses into clouds

• Radiated heat from the ground causes a warm updraft

You would expect to experience ​ (a)   , ​ (b)   during relief rainfall?

• long lasting

• light drizzle

• heavy thunderstorm

• snowfall

• torrential downpour

• a short

Answer explanation

During relief rainfall, you would expect to experience long lasting and light drizzle. These conditions are typical as the rain tends to be gentle and prolonged, rather than heavy or intense.

A weather feature known as a ​ (a)   often leads to frontal rainfall.

• derpession

• convection current

• tornado

• earthquake

Answer explanation

A depression is a weather system characterized by low pressure, which often leads to the lifting of air and subsequent frontal rainfall. This makes 'depression' the correct answer, as the other options do not directly relate to rainfall.
