- Sabarmati River is one example that originates in Rajasthan (Udaipur) and meets the Arabian Sea.
- Only a few rivers in Rajasthan do not drain into the sea. They drain into salt lakes and get lost in the sand with no outlet to the sea.
- Besides these, the Desert Rivers flow for some distance and are lost in the desert. These are Luni, Machhu, Rupen, Saraswati, Banas, Ghaggar and others.

The Terai region is a plain swampy landscape south of the Shiwaliks. Let us explore this answer in more detail:
Terai Region:
- The Terai region is a strip of land that stretches along the foothills of the Himalayas, from the Yamuna River in the west to the Brahmaputra River in the east.
- It is a low-lying region that covers parts of Nepal, India, and Bhutan.
- The region is known for its dense forests, grasslands, and wetlands.
- The Terai is an important ecological region that supports a high level of biodiversity.
Plain Swampy Landscape:
- The Terai region is characterized by a plain swampy landscape.
- The region is flat and low-lying, with an average elevation of about 200 meters.
- The soil in the Terai is fertile and supports a variety of crops, including rice, sugarcane, and wheat.
- The region is also home to a number of wetlands, including the Beels and Haors, which are important habitats for a variety of bird species.
South of Shiwaliks:
- The Shiwalik Range is a mountain range that runs parallel to the Himalayas.
- The Terai region is located to the south of the Shiwaliks.
- The Shiwaliks act as a barrier to the monsoon winds, which results in heavy rainfall in the Terai region.
- The region is prone to flooding during the monsoon season, which can cause significant damage to crops and infrastructure.
In conclusion, the Terai region is a plain swampy landscape located south of the Shiwaliks. It is an important ecological region that supports a high level of biodiversity and is known for its fertile soil and wetlands.

Suitable Crops for Lower Gangetic Plain
The Lower Gangetic plain is a highly fertile region that is suitable for cultivation. The region has a humid climate with high temperature throughout the year. The crops that are grown in this region should be able to withstand the high temperature and humidity. The following are the suitable crops for this region:
Paddy and Jute
Paddy and Jute are the most suitable crops for the lower Gangetic plain. They are able to withstand the high temperature and humidity of the region. Paddy is a major crop in this region as it requires a lot of water for growth. It is grown in both the kharif and rabi seasons. Jute is also a major crop in this region. It is grown in the kharif season and requires a lot of water for growth.
Wheat and Jute
Wheat and Jute are also suitable crops for the lower Gangetic plain. Wheat is grown in the rabi season and requires irrigation. It is a high-yielding crop that is grown in this region. Jute, as mentioned earlier, is also a major crop in this region.
Paddy and Cotton
Paddy and Cotton are suitable crops for the lower Gangetic plain. However, Cotton is grown in the drier parts of the region. It requires less water than Paddy and is grown in the kharif season. Paddy, as mentioned earlier, is a major crop in this region.
Wheat and Cotton
Wheat and Cotton are not very suitable crops for the lower Gangetic plain. Wheat requires irrigation and is grown in the rabi season. Cotton, as mentioned earlier, is grown in the drier parts of the region.
Conclusion
In conclusion, the most suitable crops for the lower Gangetic plain are Paddy and Jute. These crops are able to withstand the high temperature and humidity of the region. Other crops such as Wheat and Cotton are also grown in this region but are not as suitable as Paddy and Jute.

 | Anagha Iyer answered |
- Bangar soils are less prone to floods. - This statement is correct. Bangar represents the older alluvium in the riverine system of the northern plains and lies above the flood plains. It is not regularly replenished by floodwaters, hence, less prone to floods.
- Bangar soils are nothing but new alluvial soils. - This statement is incorrect. It's actually the Khadar soils that are the newer or young alluvial soils, replenished by annual floods, making them more fertile. Bangar, in contrast, consists of older alluvium.
- Bangar soils are more fertile than Khadar soils. - This statement is incorrect. Khadar soils, being newer alluvium replenished by annual floods, are more fertile than Bangar soils, which are older and have been leached due to the absence of such replenishment.
- Khadar plains are those that are low-lying next to a river. - This statement is correct. Khadar lands are newer alluvial plains found in the lower areas and are prone to flooding, which also makes them more fertile due to the newer sediments deposited by river floods.

 | Future Foundation Institute answered |
- Statement 1: True
Geological evidence suggests that during the Permo-Carboniferous period, parts of Rajasthan, including the Rajasthan Plains, were submerged under a shallow sea. Fossils and sedimentary formations in the region support this. - Statement 2:False
Most lakes in Rajasthan are saline, such as Sambhar Lake, Didwana Lake, and Pachpadra Lake, due to high evaporation rates and limited inflow of freshwater. However, there are exceptions like Lake Pichola and Fateh Sagar, which are freshwater lakes but not dominant. - Statement 3:False
The Luni River is the largest river in the Rajasthan Plains, but it is a seasonal river and does not reach the ocean. Instead, it ends in the marshy areas of the Rann of Kutch, where its water dissipates.
Therefore,Correct Answer- Option C

- According to the variations in relief features, the Northern plains can be divided into four regions.
- After descending from the mountains, the rivers deposit pebbles in a narrow belt of about 8 to 16 km in width lying parallel to the slopes of the Shivalik.
- It is known as bhabar. All the streams disappear in this bhabar belt. South of this belt, the streams and rivers re-emerge and create a wet, swampy and marshy region known as Terai. This was a thickly forested region full of wildlife.
The forests have been cleared to create agricultural land and to settle migrants from Pakistan after partition. Dudhwa National Park is located in this region.
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. 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.

- India's third geological division comprises the plains formed by the river Indus, the Ganga and the Brahmaputra Originally.
- It was a geo-synclinal depression that attained its maximum development during the third phase of the Himalayan mountain formation approximately 64 million years ago.
- Since then, it has been gradually filled by the sediments brought by the Himalayan and Peninsular rivers Average depth of alluvial deposits in these plains ranges from 1,000 to 2,000 m.
Geosyncline
- It is a linear trough of subsidence of the Earth's crust within which vast sediment accumulate.
- The filling of a geosyncline with thousands or tens of thousands of feet of sediment is accompanied in the late stages of deposition by folding, crumpling, and faulting of the deposits, the intrusion of crystalline igneous rock and regional uplift along the axis of the trough generally complete the history of a particular geosyncline, which is thus transformed to a belt of folded mountains,
