Question

Observe the map. Name the coastal areas that will experience changes in temperature. Give the reason for this.

Answer 1

The coastal areas affected by warm currents experience a rise in temperature, while those affected by cold currents experience a fall in temperature.

Examples include:

• Western Europe – warmed by the North Atlantic Drift.
• Eastern coast of North America – influenced by the warm Gulf Stream and cold Labrador Current.
• Western coast of South America – cooled by the Humboldt (Peru) Current.
• Eastern coast of South America – warmed by the Brazil Current.
• Western coast of southern Africa – cooled by the Benguela Current.
• Eastern coast of southern Africa – warmed by the Agulhas Current.
• Western coast of Australia – cooled by the West Australian Current.
• Eastern coast of Australia – warmed by the East Australian Current.

Reason: Ocean currents carry warm or cold water from one region to another. They heat or cool the air above them, thereby changing the temperature of nearby coastal areas.
