Geography Flashcards

What is the 'water footprint' of a product?

Answer: The total volume of freshwater used to produce the product throughout its supply chain

The water footprint measures the total volume of freshwater used to produce a product, including all stages of production across the entire supply chain.

What happens at a convergent plate boundary between two oceanic plates?

Answer: One plate subducts beneath the other, creating ocean trenches

When two oceanic plates converge, the denser plate subducts beneath the other, forming ocean trenches (the deepest parts of the ocean) and volcanic island arcs.

What is the main advantage of mixed farming?

Answer: It reduces dependence on a single crop and spreads risk

Mixed farming combines crops and livestock, spreading the risk of crop failure and allowing waste products from one to benefit the other (e.g., animal manure as fertiliser).

What is 'refugee' status?

Answer: Someone who has fled their country due to persecution, war, or disaster

A refugee is someone who has been forced to flee their country due to persecution, conflict, violence, or natural disaster, and cannot safely return home.

What is the relationship between altitude and temperature?

Answer: Temperature generally decreases as altitude increases

Temperature decreases by approximately 6.5°C for every 1000 metres increase in altitude (the environmental lapse rate), which is why mountain tops are cold.

What is the 'multiplier effect' in an economy?

Answer: When an initial investment leads to greater overall economic activity

The multiplier effect occurs when an initial injection of money into the economy (e.g., new factory) generates additional economic activity as that money circulates and is spent multiple times.
