Question 2

Which of the following best describes 'demographic transition'?

Accepted Answer

The historical shift from high birth and death rates to low birth and death rates

Answer

The demographic transition model describes how countries typically move from high birth and death rates (pre-industrial) to low birth and death rates (post-industrial) as they develop economically.

Question 3

What is the impact of deforestation on the water cycle?

Accepted Answer

It reduces transpiration and increases surface runoff, leading to flooding and reduced groundwater recharge

Answer

Deforestation removes trees that contribute to transpiration, disrupts the water cycle, reduces groundwater recharge, increases surface runoff (flooding risk), and causes soil erosion.

Question 4

What is an aquifer?

Accepted Answer

An underground layer of rock or sediment that holds water

Answer

An aquifer is an underground layer of permeable rock, sediment, or soil that contains and can transmit groundwater, serving as a major source of freshwater.
