Test: Deserts - Question 1

Which of the following is a characteristic of hot deserts known as trade wind deserts?

Detailed Solution for Test: Deserts - Question 1
Hot deserts, also known as trade wind deserts, are primarily located on the western coasts of continents between latitude 15° and 30°North and South of the equator. This positioning is influenced by the off-shore trade winds, and the regions are in the rain shadow zone, leading to aridity.
Test: Deserts - Question 2

What is a significant factor contributing to the aridity of hot deserts?

Detailed Solution for Test: Deserts - Question 2
Hot deserts are located in the Horse Latitudes or Sub-Tropical High-Pressure Belts, where the air is descending. This descending air leads to aridity, as it gets compressed and warm, resulting in decreased moisture-holding capacity.

Test: Deserts - Question 3

Which type of rainfall is the primary contributor to precipitation in deserts?

Detailed Solution for Test: Deserts - Question 3
Deserts mostly experience rainfall due to convectional rainfall and thunderstorms. Convectional rainfall occurs when the air near the ground is heated, rises, cools, and condenses to form clouds, leading to precipitation.
Test: Deserts - Question 4
Why do coastal deserts generally have lower temperatures than interiors?
Detailed Solution for Test: Deserts - Question 4
Coastal deserts generally have lower temperatures than interiors because of the presence of cold ocean currents along the western coast. These currents contribute to stabilizing the air over the coast, preventing cloud formation and reducing temperatures.
Test: Deserts - Question 5
What is the main reason for the significant diurnal temperature range in deserts?
Detailed Solution for Test: Deserts - Question 5
The significant diurnal temperature range in deserts is mainly due to the low specific heat of the desert soil. Desert soil heats up and cools down rapidly, leading to large temperature variations between day and night.
Test: Deserts - Question 6
What type of vegetation is predominant in both hot and mid-latitude deserts?
Detailed Solution for Test: Deserts - Question 6
The predominant vegetation in both hot and mid-latitude deserts is xerophytes or drought-resistant scrub. This includes bulbous cacti, thorny bushes, long-rooted wiry grasses, and scattered dwarf acacia.
Test: Deserts - Question 7
Which type of settlers primarily pursues a livestock economy, wandering through deserts with their herds?
Detailed Solution for Test: Deserts - Question 7
Nomadic herdsmen pursue a livestock economy, wandering through deserts with their herds in search of water and green pastures. Examples include the Bedouins of Arabia, the Tuaregs of Sahara, and the Mongols of the Gobi desert.
Test: Deserts - Question 8
Which factor is a cause for the formation of tropical hot deserts?
Detailed Solution for Test: Deserts - Question 8
Tropical hot deserts are formed due to the presence of the subtropical high-pressure cell, rain shadow effect in the belt of easterly trade winds, and the influence of cold currents off the west coast of the continents at these latitudes.
Test: Deserts - Question 9
Which desert belt lies in the vicinity of cold currents, contributing to its aridity?
Detailed Solution for Test: Deserts - Question 9
The Atacama Desert lies in the vicinity of cold currents, contributing to its aridity. Cold currents have a desiccating effect on the air, leading to the formation of desert belts.
Test: Deserts - Question 10
What is the main objective of the Desert Development Program by the Government of India?
Detailed Solution for Test: Deserts - Question 10
The main objective of the Desert Development Program by the Government of India is to enhance sustainable practices, promote conservation of land in deserts, and implement measures for the overall development of desert regions.
