World Geography Mixed Practice — MCQs with Answers (Set 3)

Quinary activities sit at the very top of the service hierarchy: high-level decision-making by top government officials, senior executives, and heads of major institutions.

Quaternary activities involve producing and processing knowledge itself. Scientific research is a classic example, unlike retail selling or transport, which are tertiary.

Wholesale traders buy goods in bulk directly from producers and sell them on in smaller batches, dealing mostly with other businesses rather than the final customer.

Tertiary activities don’t make anything physical themselves; they connect primary and secondary producers to the people who actually use their goods.

Modern national borders, land privatisation, government resettlement schemes, and expanding desert conditions in regions like the Sahel have all shrunk the open land nomadic herders once moved across freely.

The Pampas of Argentina, along with the western United States and Australia’s interior, are major commercial livestock ranching regions.

Ranching raises animals on fenced, managed land specifically for market sale, using scientific breeding, while nomadic herding moves seasonally to feed the herder’s own community.

Reindeer herding is a classic example of nomadic herding practised across the Arctic tundra of Scandinavia and Russia.

Nomadic herding moves livestock across dry or cold regions in search of pasture and water, following a seasonal cycle, and is subsistence-oriented rather than commercial.

Occupational structure is the share of a workforce employed in primary (farming, mining), secondary (manufacturing), and tertiary/quaternary (services, knowledge work) activities — a rough proxy for a country’s stage of development.

As economies industrialise, farm labour typically moves to factory and service jobs, shifting population share from rural to urban areas over time.

An expansive pyramid has a wide base tapering to a narrow top, since high birth rates are adding far more young people than old people are dying off — typical of developing countries.

A population pyramid stacks age groups as horizontal bars, split by sex (males on one side, females on the other), showing age and sex composition together.

Sex ratio is conventionally written as the number of females per 1,000 males, letting regions of very different sizes be compared on the same scale.

“Population explosion” describes the very rapid growth typical of Stage 2, when death rates have already fallen sharply but birth rates have not yet followed — it is a temporary phase, not a permanent state.

Doubling time is how long it would take a population to double, given its current growth rate. A faster growth rate produces a much shorter doubling time.

Stage 1 (High Stationary) describes pre-industrial societies where both birth and death rates are high, so population barely grows — not because growth is controlled, but because deaths roughly balance births.

Distribution describes where people live across space. Density divides population by area to show how crowded a place is — the two answer different questions.

Most developed countries have already reached Stage 4, with slow or shrinking populations. Today’s rapid growth is concentrated in developing countries still moving through Stage 2 or Stage 3.

The Mediterranean climate (Cs) is defined by its reversed seasonal rainfall: hot, dry summers under the subtropical high, and mild, rainy winters under the westerlies.

While inversion elsewhere is usually a brief, clear-night phenomenon, it is normal throughout the year over polar regions.

The normal lapse rate is 6.5°C per 1,000 m, meaning temperature is highest at ground level and decreases with height.

35 units are reflected back to space as albedo; the remaining 65 units are absorbed, 14 by the atmosphere and 51 by the earth’s surface.

Convection is the vertical transfer of heat through rising air currents, and this process is confined to the troposphere.

On 4 July the earth reaches aphelion, its farthest point from the sun at 152 million km.
