Question 2

What is the primary cause of desertification in semi-arid regions?

Accepted Answer

Overgrazing, deforestation, and unsustainable farming practices degrading land

Answer

Desertification is mainly driven by human activities such as overgrazing, unsustainable agriculture, and deforestation, which degrade vegetation cover and soil quality in semi-arid areas.

Question 3

In the context of glacial landforms, what is an 'arête'?

Accepted Answer

A narrow, knife-edge ridge formed between two corries or glacial valleys

Answer

An arête is a sharp, narrow ridge formed when two adjacent glaciers or corries erode the land from either side, leaving a thin rock wall between them.

Question 4

Which of the following is the most accurate definition of 'Food Security'?

Accepted Answer

When all people at all times have physical and economic access to sufficient, safe, and nutritious food

Answer

The FAO definition of food security encompasses availability, access, utilisation, and stability of food supplies, not simply domestic food production.

Question 5

What does the Human Development Index (HDI) primarily measure?

Life expectancy, education, and income as a composite measure of human well-being

Answer

HDI combines three dimensions — life expectancy, education (mean and expected years of schooling), and GNI per capita — to provide a broader measure of development than GDP alone.
