Question D.1:

Plants in the Sahara have long roots and small, leathery leaves.

Answer:

Plants in the Sahara have long roots and small, leathery leaves. This is because the Sahara desert records very high temperature. Coupled with low precipitation and cloudless days, the rate of evaporation of water from the leaves of plants is very high. That is why plants in this region have small and leathery leaves to reduce transpiration. Moreover, the roots of the plants are long as they have to dig deep in order to access the limited groundwater resources.

Question D.2:

Ladakh receives scanty rainfall.

Answer:

Ladakh receives scanty rainfall because it lies to the north of the Himalayas, in their rain shadow zone. The south-west monsoons cause heavy rains on the southern slopes of the Himalayas. These winds are rendered moistureless by the time they cross the Himalayas and reach Ladakh. Hence, the rainfall in Ladakh is very scanty.

Question E.1:

Describe the landform features of the Sahara desert.

Answer:

Landform features of the Sahara desert: The most important factor in shaping the landform features of the Sahara desert is wind. The wind action, over the years, has shaped the landscape of the desert. The Sahara is not entirely a sandy desert. In fact, only 1/4th of the total area is covered by sand in the form of shifting sand dunes, also known as erg. There are also large areas covered by rocks and pebbles, also known as reg, and large portions made up of smooth bedrock, also known as Hamada. There are a few mountain ranges and plateaus towards the northern end of the Sahara, such as the Ahaggar and the Atlas mountains.

Sahara also has a few oases where water is available. Some famous ones are Kufra and Bilma.

Question E.2:

Describe the landform features of Ladakh.

Answer:

Ladakh is a cold and barren desert, situated among different mountain ranges. Because of its extremely remote location, it is sometimes known as ‘Moonland’. The major mountain ranges in the Ladakh range are the Karakoram Range and the Ladakh range. There are many high mountain peaks, the most notable of them being the K2.
The Ladakh region is drained by many rivers, the Indus being the largest. Rivers Shyok, Zaskar, Numbra and Suru are its tributaries. These rivers have carved deep valleys in the otherwise rocky desert surface. There are a few large lakes in this region as well, the Pangong Tso being the largest.
