When the streams flow in different directions from a central peak or dome-like structure, a pattern is developed which is called as:
A lake formed when a meandering river is cut off from the mainstream is known as:
An oxbow lake starts as a curve, or meander, in a river. A lake forms as the river finds a different, shorter, course.
The meander becomes an oxbow lake along the side of the river.
Oxbow lakes usually form in flat, low-lying plains close to where the river empties into another water body.
On these plains, rivers often have wide meanders. Meanders that form oxbow lakes have two sets of curves: one curving away from the river's straight path and one curving back.
The corners of the curves closest to each other are called concave banks. The concave banks erode over time.
The force of the rivers flowing water wears away the land on the meander's concave banks. The banks opposite the concave banks are called convex banks.
The opposite of erosion happens here. Silt and sediment build up on convex banks. This build-up is called deposition.
Erosion and deposition eventually cause a new channel to be cut through the small piece of land at the meander's narrow end. The river makes a shortcut. Oxbow lakes are the remains of the bend in the river.
The Sutlej, Beas, Ravi, Chenab and Jhelum are the major tributaries to the river:
Indus River, Tibetan and Sanskrit Sindhu, Sindhi Sindhu, or Mehran, a great trans-Himalayan river of South Asia.
It is one of the longest rivers globally, with a length of some 2,000 miles (3,200 km).
Its total drainage area is about 450,000 square miles (1,165,000 square km), of which 175,000 square miles (453,000 square km) lie in the ranges and foothills of the Himalayas, the Hindu Kush, and the Karakoram Range; the rest is in the semiarid plains of Pakistan.
The Amravati, the Bhavani, the Hemavati, the Kabini, etc. are the main tributaries of:
Kaveri River, Kaveri also spelt Cauvery, the sacred river of southern India. It rises on Brahmagiri Hill of the Western Ghats in southwestern Karnataka state, flows in a southeasterly direction for 475 miles (765 km) through the states of Karnataka and Tamil Nadu, and descends the Eastern Ghats in a series of great falls.
Right, Bank Tributaries are :- Hemavati , Shimsha , Arkaveri , Chovrai , Turunan Muttai . Left bank Tributaries are :- Lakshmantirath , Kabini ,Suvarnevati , Bhavani , Noyil , Amravati.
Climate is an important geographical phenomenon that determines many things like vegetation, fauna, and living comfort. Consider the following statements in this regard and pick out the incorrect ones:
1. Weather refers to the total of weather conditions and variations over a large area for a long period of time.
2. Climate refers to the state of the atmosphere over an area at any point in time.
Weather, state of the atmosphere at a particular place during a short period of time.
It involves such atmospheric phenomena as temperature, humidity, precipitation (type and amount), air pressure, wind, and cloud cover.
The weather differs from the climate in that the latter includes the synthesis of weather conditions that have prevailed over a given area during a long time period—generally 30 years.
For a full discussion of the elements and origins of weather, see climate. For the treatment of how conditions in space affect satellites and other technologies, see space weather.
As most commonly defined, weather occurs in the troposphere, the lowest region of the atmosphere that extends from the Earth's surface to 6–8 km (4–5 miles) at the poles and about 17 km (11 miles) at the Equator. Weather is largely confined to the troposphere since almost all clouds occur and almost all precipitation develops.
Consider the following statements about the characteristics of Indian Monsoon.
1. Monsoon season in India is associated with continuous rainfall without breaks.
2. Monsoon causes flood as well as drought.
3. Monsoon winds are pulsating and unstable in nature and direction.
4. Tropical cyclones originate in the Andaman Sea and cause heavy rain in India's eastern coast post-retreat of monsoon.
Which of these is/are not correct?
Characteristics of the Indian Monsoon
1. These winds generally strike the Indian coast in the first week of June, but their arrival and departure may be before time or may be delayed.
2. Monsoon is not steady winds. They are irregular in nature affected by different atmospheric conditions i.e. due to regional climatic conditions.
3. Monsoons are not equally distributed. The spatial distribution of rainfall is uneven – some regions may receive heavy rains while the others will have to be content with meagre or scanty rains.
4. When the monsoon arrives, it gives heavy rainfall which continues for several days. This is known as the 'burst of monsoon'. This occurs mainly at the Kerala coast where it reaches first.
5. Generally, these winds start retreating by the end of September. But, sometimes, their departure may be delayed till October or they may retreat even much earlier.
The Cold Weather Season begins from mid-November in Northern India and stays till February. Consider the following statements about the Cold Weather Season?
1. During this season, the Northeast Trade winds prevail over the country which blows from sea to land and hence, for most of the country, it is a dry season
2. A characteristic feature of the Cold Weather Season over the Northern Plains is the inflow of cyclonic disturbances from the west and the northwest
3. The Peninsular region does not have a well-defined cold season
Select the correct answer from the code given below:
The cold weather season begins with November in north India, and by the beginning of December, the whole country comes under its grip.
In this season the southerly branch of the jet stream occupies position south of the Himalayas indicating that oil more the Northern Hemisphere polar dynamics in command of the situation.
The westerly jet stream's return is accompanied by the restriction of light north-east trade winds (monsoon) toll surface, withdrawal of the ITC, formation of antic clinic cell over northwestern India and dry wealth conditions prevailing over most of the part of the country.
The latitude that pass through Sikkim does not pass through:
5. Uttar Pradesh
Consider the following statements:
1. Retreating monsoon season is 3 months long.
2. The temperature falls during the retreating monsoon season.
Which of the following statements are correct:
Retreating monsoon season commences with the southwest monsoon [mid-September – November] and lasts till early January.
It is a 3-month long process where it starts from the peninsula in October and from the extreme southeastern tip by December.
The southwest monsoons withdraw from the Coromandel coast in mid-December.
In Punjab, the southwest monsoons withdraw from there in the second week of September. During this period, the temperature comes down sharply.
The sky also becomes clear. The most severe and destructive tropical cyclones are originated in the Indian seas and the Bay of Bengal during the retreating monsoons.
During the retreating monsoon season in India, the southeastern coast receives much rainfall; tropical cyclones also occur.
The state of Tamil Nadu receives almost half of its annual rainfall during this time. This is called the winter monsoon or the northeast monsoons.
Which of the following statements is/are correct?
1. Mahanadi river drainage basin is shared by Maharashtra, Chhattisgarh, Jharkhand and Orissa.
2. Godavari River drainage basin is the largest among peninsular rivers.
3. There is no west flowing river in Madhya Pradesh
The major west-flowing rivers in Peninsular India are Narmada and Tapi. It is located mainly in Madhya Pradesh. The Narmada River is also known as the Rewa River. The River originates from the Maikala range near Amarkantak.
What is the definition of sex ratio?
What does infant mortality mean?
Infant Mortality Rate (IMR) is the number of deaths per 1,000 live births of children under age of one year. The present level of IMR (33 infant deaths per thousand live births, for the year 2017) is about one-fourth as compared to 1971 (129 infant deaths per thousand live births). In the last ten years, IMR has witnessed a decline of about 36.7% in rural areas and about 36% in urban areas.
What is the Maternal Mortality Rate?
The Maternal Mortality Rate (MMR) is the annual number of female deaths per 100,000 live births from any cause related to or aggravated by pregnancy or its management (excluding accidental or incidental causes).
For its calculation, the number of deaths due to infant birth is divided by the total number of infant births.
The Maternal Mortality Ratio (MMR) in India has declined from 167 in 2011-2013 to 130 in 2014-2016, according to a special bulletin issued by the Health Ministry today. MMR is defined as the proportion of maternal deaths per 1,00,000 live births.

Which states of India have the lowest and highest Infant Mortality Rate respectively?
Which are the three main factors that cause population change?
What is the unit of population density measurement?
Which state in India has the highest literacy rate?
Literacy rate of population is defined as the percentage of literates to the total population age 7 years and above.
