Which type of rainfall forms when warm air rises over cold air?
Fronal Rainfall
What happens to the weather in a low-pressure area?
Clouds form, often rain
What happens to the weather in a high-pressure area?
Clear skies, dry weather
What is the dry side of a mountain called?
Leeward Side
What natural disaster occurs when rivers overflow due to heavy rain?
Floods
Which rainfall type is most affected by air masses?
Frontal Rainfall
What forms when rising warm air cools and water vapour condenses?
Clouds
What natural disaster can occur after weeks of high pressure?
Droughts
What is an air mass?
A large body of air with similar temperature and humidity
Which type of air mass is cold and dry?
Continental Polar
Why does rising air cool as it goes higher?
Because it expands in lower pressure and loses heat
Air pressure drops as it goes higher
Which side of the mountain receives the most rainfall?
Windward Side
Which type of rainfall often produces thunderstorms?
Convectional Rainfall
What causes storm surges during cyclones?
Strong winds pushing water + low pressure + high tides
What type of natural disaster is caused by very strong rotating storms over warm oceans?
Cyclones, hurricanes, typhoons
Which type of air mass is warm and moist?
Maritime Tropical
What can happen if a tropical cyclone reaches the coast?
Storm surge / flooding / strong winds
Why do thunderstorms usually happen in the afternoon?
The ground is hottest → warm air rises → condensation → clouds → heavy rain
Which rainfall type occurs when moist air is forced over a mountain?
Relief Rainfall
Which rainfall type is caused when warm air rises quickly from a hot surface?
Convectional Rainfall
