The topographical features of Pothwar Plateau:

The Pothwar Plateau presents a badland topography owing to its dissected, eroded and faulted land. The Soan river forms alluvial plains which are agriculturally productive.

1. Ridges and residual hills: These features are formed by the erosion of soft rock through the action of running water and fast blowing winds. Kala Chitta and Khairi are important residual hills of Pothwar plateau.

2. Faulted land: During the mountain building process, the land is weak and shows off cracks.

3. Troughs and depressions: These features are formed when soft rocks are eroded by water and wind blow away the loose soil which creates depression and trough.

4. Ravines: Ravines are deep channels created by the erosion of soft water and carry running water particularly during rainy season.

The important passes situated in northern and western mountains are:

1. Khyber Pass: Connects Pakistan with Afghanistan.

2. Bolan Pass: Connects Balochistan with Sindh and Punjab provinces.

3. Lowari Pass: Links Chitral Valley with Dir Valley.

4. Khunjerab Pass: Highest paved international border crossing, connecting Pakistan with China.

5. Gomal Pass: Historically significant trade route between Afghanistan and the Indian subcontinent.

Ans: The Indus Plain:

Ans: Inland drainage:
Inland drainage refers to the phenomenon where rivers or streams do not flow into the sea but instead terminate in closed basins, deserts, or evaporate due to arid conditions.

Examples:

Hamun-i-Mashkel:
Located in Balochistan province, this is an endorheic basin where rivers such as the Mashkel and Baddu rivers terminate. The water either evaporates or infiltrates into the ground, leading to the formation of seasonal lakes.

Rann of Kutch:
While predominantly in India, part of the Rann of Kutch extends into Pakistan. It's a vast salt marsh that experiences inland drainage, where streams and rivers flow into the marshlands but do not have an outlet to the sea.

Thar Desert:
The Thar Desert in southeastern Pakistan experiences inland drainage, where ephemeral rivers and streams such as the Luni River terminate in salt lakes, or simply evaporate due to the arid conditions.
