Which region encircles the equator in Africa, including locations like East Africa and the Congo?
Tropical regions
How do wind-driven ocean currents affect temperatures?
Cause warm air above warm ocean currents and cold air above cold ocean currents
How do onshore winds affect rainfall?
Bring moisture to coastal areas, making inland places drier
What is the influence of the Benguela Current on desert formation in South Africa?
Causes fog formation in the Namib Desert
Which ocean current leads to more rain on the east coast of South Africa and Mozambique?
Agulhas Current
What role does evaporation from the ocean play in precipitation over landmasses?
Is the primary source of precipitation over Earth's landmasses
How do warm ocean currents affect precipitation in maritime climates?
Result in warmer air capable of holding more water vapor, leading to increased rain
What type of precipitation occurs when air rises up a mountain and cools down?
Orographic rain
Why do coastal areas tend to receive more rain compared to inland cities?
As a result of warm ocean currents
What causes noticeable differences between summer and winter seasons in Africa?
Tropic line shifts
What type of wind blows down mountain slopes at night in mountainous regions?
Cold mountain wind
What happens to air as it subsides towards the Earth's surface?
It warms up
Why does condensation and rainfall occur during subsidence?
Because the subsiding air can hold more water
What causes air to move from a high-pressure area to a low-pressure area?
Convergence
What is the type of rainfall received by areas that lie in the path of mid-latitude cyclones?
Frontal rain
Why do mid-latitude cyclones carry frontal rain?
Due to westerly winds blowing from high-pressure areas
What is the rate at which rising air cools known as?
Dry Adiabatic Lapse Rate
What happens when cooling air holds less water vapor?
Condensation occurs
What contributes to the creation and persistence of the Sahara Desert in North Africa?
Subsiding air and high-pressure belts
Where does condensation not occur according to the text?
In the descending, warming air
What causes the formation of cold fronts according to the text?
Mid-latitude cyclones
What is the zone formed by converging tropical easterlies called?
Intertropical Convergence Zone
What leads to rainfall in equatorial regions according to the text?
Convergence of tropical easterlies at the ITCZ
Which process leads to Cyclonic (or frontal) rain in Western Cape and North Africa?
Mid-latitude cyclones leading to westerly winds convergence
What causes the rising of air at the polar front according to the text?
Mid-latitude cyclones formation
Which African climate region experiences very high daytime temperatures and nighttime temperatures around 5°C?

Which climate region in Africa has cold, wet winters with temperatures around 12°C?
Mediterranean region
What distinguishes the Semi-arid regions from desert regions in Africa with regard to rainfall?
Desert regions receive less than 250 millimeters annually.
Which African climate region is situated mainly on the South African eastern coast and has an annual temperature range of 11°C?
Tropical region
What is the average summer temperature in the Humid subtropical region of Africa?
26°C
