Q2: Multiple Choice Questions (MCQs)

(ii) The highest plateau globally is known as:
(a) Sahara Plateau
(b) Deccan Plateau
(c) Plateau of Tibet
(d) Rocky Plateau
Ans: (c)
The Plateau of Tibet is often referred to as the "roof of the world" due to its high elevation and extensive size.

(iii) Deserts are characterized by:

(a) Heavy rainfall
(b) Dense vegetation
(c) Minimal rainfall and extreme conditions
(d) Frequent snowfall
Ans: (c)
Deserts are known for their arid conditions, with very little rainfall and extreme temperature fluctuations.

(iv) Which landform often contains oases?
(a) Mountains
(b) Rivers
(c) Plateaus
(d) Deserts
Ans: (d)
Oases are small areas within deserts where water is present, allowing vegetation to grow and providing a habitat for both plants and people.

(v) What is the final stage of a river's journey called?
(a) Upper Course
(b) Middle Course
(c) Lower Course
(d) River Mouth
Ans: (c)
The lower course of a river is the final stage of its journey when it reaches a larger body of water, such as a sea or an ocean.

Q3: True or False

(ii) Mountains are primarily formed by river deposits.
Ans: False
Mountains are primarily formed by tectonic processes, volcanic activity, and erosion, not by river deposits.

(iii) Cold deserts have scorching hot temperatures.
Ans: False
Cold deserts have extreme temperature variations, including cold nights, but they are not characterized by scorching hot temperatures like hot deserts.

(iv) The middle course of a river is characterized by deep valleys and waterfalls.
Ans: False
The middle course of a river is characterized by reduced speed, meandering, and the formation of loops, not deep valleys and waterfalls.

(v) Oases are areas within deserts where water is scarce.
Ans: False
Oases are small areas within deserts where water is available, making them relatively more fertile and hospitable compared to the surrounding arid areas.

Q4: Match the Following

Q5: Short Answer Questions

(ii) How are plateaus formed, and why are they important for agriculture?
Ans: Plateaus are formed through various geological processes, such as volcanic activity, tectonic uplift, and erosion. They are important for agriculture because they often have fertile soils due to river deposits. These regions can support farming and grazing activities. Plateaus with significant heights may also have waterfalls that enhance their natural beauty and provide resources for irrigation.

(iii) Differentiate between hot deserts and cold deserts.
Ans: Hot deserts and cold deserts differ primarily in their temperature characteristics. Hot deserts have scorching hot temperatures during the day and can experience relatively mild nights. Cold deserts, on the other hand, have extreme temperature fluctuations with very cold nights, and they can experience snowfall.

(iv) Describe the three stages of a river's journey.
Ans: The three stages of a river's journey are:

• Upper Course: The river starts in the mountains, characterized by steep slopes and minimal water flow. Deep valleys and waterfalls may form as the river gains speed.
• Middle Course: The river enters the plains, and its speed decreases as it flows on flatter terrain. Meandering becomes prominent, and loops form in this stage.
• Lower Course: The river reaches its final destination, often merging with a larger water body. It divides into multiple channels, and sediment accumulation leads to the formation of a delta.

(v) Why are oases significant in desert regions?
Ans:  Oases are significant in desert regions because they provide relief amidst the arid surroundings. These small areas with water support the growth of vegetation, allowing settlements and agriculture to thrive. Oases serve as important resources for both people and animals in desert regions.
