MAJOR LANDFORMS OF THE EARTH 

Answer the following question:-

Que-1 What is aggradation?

Ans-1 A modification of the earth's surface in the direction of uniformity of grade by deposition is called aggradations.

 

Que-2What are residual mountains?
Asn-2 Mountains that have been eroded by the agents of degradation such as winds, rain, frost and running water leaving behind only the hard rocks are known as residual mountains. These hard rocks that are left behind are known as the residual mountains.

Que-3 What is tableland?
Ans-3  A table or tableland is a mountain that have a flat top.

Que-4 what are mountains?  
Ans-4 A mountain is a large landform that rises above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally considered to be steeper than a hill. Mountains are formed through tectonic forces or volcanism.

Que-5  what are the uses of plateaus?
Ans-5  The uses of plateaus are.

1.The grasslands are extensively used for live stock rearing.

2. The plateaus which have been formed by the solidification of lava, are rich in black soil they are very fertile and good for crops like cotton and sugarcane.

3.The scenic beauty of plateau areas also attracts many tourists.

 Que-6 what are plains and write the advantages of plains?
Ans-6 Plains are also called as plateaus which are flat land and have short height. They cover about 40% of earths surface.

Advantages of plains are

1) It helps human in fulfilling their need of food and shelter

2) Reduces the risk of floods

3) Increases fertility leading to more production

4) Encourages to practice agriculture

5) Increase in natural resources.

Chapter-2 PHYSICAL FEATURES OF INDIA

 

A. Choose the correct answer from the four alternatives given below.
1. A landmass bounded by sea on three sides is reffered to as

a.Coast                         b.Peninsula                              c.Island(√)

2.Mountain ranges in the eastern part of India forming its boundary with Myanmar are collectively called.

a. Himachal                 b.Purnachal(√)                         c.Uttarakhand

3. The western coastal strip. Wouth of Goa is referred to as

a. Coromandel             b.Kannad( √)                           c.konkan

4. The highest peak in the eastern ghats is

a. Anai Mudi               b.Kanchenjunga                      c.Mahendragiri(√)

 

B.Answer the following questions briefly:-

Que-1What is the bhabar?
Ans. The rivers, after descending from the mountains deposit pebbles in a narrow belt of about 8 to 16 km in width lying parallel to the slopes of the Shiwaliks. It is known as bhabar.

Que-2Distinguish Between Bhangar and Khadar?
Ans:Bhangar:
The largest part of the northern plain is formed of older alluvium They lie above the flood plains of the rivers and present a terrace-like feature. This part is known as bhangar

Khadar:The soil in this region contains calcareous deposits locally known as kankar. The newer, younger deposits of the flood plains are called khadar. They are renewed almost every year and so are fertile, thus, ideal for intensive agriculture.

Ques-3Distinguish Between the Western Ghats and the Eastern Ghats?
Ans:Western Ghats:
The Western Ghats are higher than the Eastern Ghats. Their average elevation is 900– 1600 metres as against 600 metres of the Eastern Ghats. The Western Ghats cause orographic rain by facing the rain bearing moist winds to rise along the western slopes of the Ghats. The Western Ghats are known by different local names. The height of the Western Ghats progressively increases from north to south.

Eastern Ghats:
The Eastern Ghats stretch from the Mahanadi Valley to the Nigiris in the south. The Eastern Ghats are discontinuous and irregular and dissected by rivers draining into the Bay of Bengal. Mahendragiri (1,501 metres) is the highest peak in the Eastern Ghats. Shevroy Hills and the Javadi Hills are located to the southeast of the Eastern Ghats

Que-4Which are the major physiographic divisions of India? Contrast the relief of the Himalayan region with that of the Peninsular plateau.

Ans 4:The physical features of India can be grouped under the following physiographic divisions:

The Himalayan Mountains

The Northern Plains

The Peninsular Plateau

The Indian Desert

The Coastal Plains

The Islands

 The Himalaya consists of three parallel ranges in its longitudinal extent. A number of valleys lie between these ranges. The northernmost range is known as the Great or Inner Himalayas or the ‘Himadri’. It is the most continuous range consisting of the loftiest peaks with an average height of 6,000 metres. It contains all the prominent Himalayan peaks.

Ques5 Write short notes on the following.(i) The Indian Desert, (ii) The Central Highlands 

Ans.5 i) The Indian Desert
The Indian desest lies towards the western margins of the Aravali Hills. It is an undulating sandy plain covered with sand dunes. This region receives very low rainfall below 150 mm per year. It has arid climate with low vegetation cover. Streams appear during the rainy season. Soon after they disappear into the sand as they do not have enough water to reach the sea. Luni is the only large river in this region. Barchans (crescent-shaped dunes) cover larger areas but longitudinal dunes become more promiment near the Indo-Pakistan boundary.

(ii) The Central Highlands
The Peninsular plateau consists of two broad divisions, namely, the Central Highlands and the Deccan Plateau. The part of the Peninsular plateau lying to the north of the Narmada river covering a major area of the Malwa plateau is known as the Central Highlands. The Vindhyan range is bounded by the Central Highlands on the south and the Aravalis on the northwest. The further westward extension gradually merges with the sandy and rocky desert of Rajasthan.
