Physical Geography of Pakistan Practice Quiz (11 questions)

1. Which relief pattern best describes Pakistan’s desert landscapes?

A. Sandy plains, bare weathered rocks, and fixed dunes unaffected by wind

B. Sandy plains, densely vegetated slopes, and mainly north–south rolling dunes

C. Sandy plains, bare weathered rocks, and mainly north–south rolling dunes

D. Sandy plains, bare weathered rocks, and mainly east–west rolling dunes

Answer: (C)

Explanation

Desert relief includes sandy plains or undulating areas, bare and weathered rocks, and mainly north–south longitudinal dunes continually reshaped by wind. The other choices reverse dune orientation, add dense vegetation, or deny wind-driven change.

2. Canal irrigation has reclaimed a patch of desert land known as a Tippa. What does this make possible there?

A. Crop agriculture without canal irrigation

B. Agriculture on the reclaimed land

C. Cattle raising in place of crop agriculture

D. Agriculture across the surrounding desert

Answer: (B)

Explanation

Agriculture is generally unsupported by desert relief and climate, but reclaimed Tippa land can support it after canal irrigation is provided. The distractors extend cultivation to unreclaimed areas, remove the irrigation condition, or substitute livestock raising for agriculture.

3. Why do seawater-covered mud flats in the Indus Delta contribute to low population density?

A. They make the ground dry and improve transport

B. They provide freshwater and increase crop production

C. They enrich the soil and expand agriculture

D. They make the soil saline and limit agriculture

Answer: (D)

Explanation

Seawater covering swampy mud flats makes the delta soil saline, limiting agriculture and contributing to low population density. The alternatives mistake saline soil for fertile soil, dry ground, or a source of freshwater.

4. A delta community has mangrove-covered areas, damaging cyclonic storms, weak transport links, and few jobs. How do these conditions relate to its population density?

A. They increase population density by creating more jobs

B. They contribute to high population density

C. They affect agriculture but not population density

D. They contribute to low population density

Answer: (D)

Explanation

Mangrove-covered areas, damaging storms, inadequate transport and infrastructure, and limited employment opportunities are among the factors contributing to the Indus Delta’s low population density. The other choices reverse the relationship or claim these conditions have no population-density effect.

5. What is a piedmont plain?

A. A broad river floodplain marked by channels that overflow each rainy season

B. A foothill plain where alluvial fans or cones are the dominant landforms

C. A high plateau dissected into ridges and ravines by running water

D. A level coastal plain built from sediment deposited by tidal waters

Answer: (B)

Explanation

A piedmont plain is a foothill plain at the foot of the Sulaiman-Kirthar or Himalayan mountains, where alluvial fans or cones dominate. A river floodplain is a related landform, but it is not defined by its position at the foot of mountains and its fan-shaped deposits.

6. Where does the Indus Delta extend from its inland boundary to the coast?

A. From the foothills near Thatta to the Jhelum River

B. From Mithan Kot to the Arabian Sea

C. From south of Thatta to the Arabian Sea

D. From the Indus headwaters to the Arabian Sea

Answer: (C)

Explanation

The Indus Delta lies south of Thatta and extends to the Arabian Sea. Mithan Kot marks the division between the upper and lower Indus Plain, not the delta’s inland boundary.

7. What is the role of alluvial terraces in the upper Indus Plain?

A. They serve as active river strips that flood each rainy season.

B. They divide adjacent rivers into named doabs.

C. They hold abandoned channels that flood after heavy monsoon rains.

D. They provide elevated farmland that is safer from floods.

Answer: (D)

Explanation

Alluvial terraces are higher uplands between rivers that are suitable for agriculture and less exposed to flooding. Active flood plains, by contrast, lie beside rivers and are flooded seasonally.

8. How does the dominant river process differ between the Upper and Lower Indus Plain?

A. Erosion is dominant in both plains, with deposition limited to the Lower Plain.

B. Deposition is dominant in the Upper Plain, while erosion is dominant in the Lower Plain.

C. Both erosion and deposition occur in the Upper Plain, while deposition is dominant in the Lower Plain.

D. Deposition is dominant in both plains, with erosion absent from the Upper Plain.

Answer: (C)

Explanation

The Upper Indus Plain experiences both erosion and deposition, whereas deposition is the main river process in the Lower Indus Plain. The claim that deposition dominates in the Upper Plain reverses this distinction.

9. How does running water shape much of the Potwar Plateau into badland topography?

A. It deposits thick layers of silt, raising broad floodplains above the surrounding land.

B. It builds alluvial fans at the foothills, creating smooth and gently sloping plains.

C. It erodes and dissects the plateau, carving ridges, ravines, gullies, and troughs.

D. It dissolves extensive limestone beds, forming caves and underground drainage networks.

Answer: (C)

Explanation

Running water has dissected and eroded the plateau, leaving ridges, ravines, gullies, and troughs that define its badland topography. Alluvial fans are associated with piedmont plains, not the principal cause of the Potwar Plateau’s badlands.

10. A planner is assessing which watercourse carries runoff from most of central Potwar. Which drainage feature should the planner identify?

A. The Jhelum River drains most of the central area.

B. The Soan River drains most of the central area.

C. Small streams drain most of the central area directly to the sea.

D. The Indus River drains most of the central area.

Answer: (B)

Explanation

The Soan drains most of central Potwar, while the southeastern region drains into the Jhelum. The Jhelum forms the eastern boundary and receives drainage from the southeast, rather than draining most of the central area.

11. Which combination best describes traditional livelihoods in Pakistan’s desert regions?

A. Cattle raising, cottage industries, and nomadic or semi-nomadic living

B. Fishing, mangrove harvesting, and permanent coastal settlement

C. Terrace farming, forestry, and seasonal mountain herding

D. Factory employment, canal farming, and dense urban settlement

Answer: (A)

Explanation

Limited water constrains agriculture, so desert livelihoods commonly include livestock raising, cottage industries, and nomadic or semi-nomadic lifestyles. Canal irrigation has enabled some reclaimed-land farming, but it does not replace these broader livelihood patterns.
