A piece of land that is completely surrounded by water on all sides is known as an island.

A peninsula is a piece of land that is bordered by water on three sides but connected to the mainland. Peninsulas are formed through a gradual rise in water level, surrounding land at low elevation.

An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea.

A (geographic) meridian (or line of longitude) is the half of an imaginary great circle on the Earth's surface, a coordinate line terminated by the North Pole and the South Pole, connecting points of equal longitude, as measured in angular degrees east or west of the Prime Meridian.

The direction of wind around a low pressure in northern hemisphere is:
  • a)
    clockwise
  • b)
    perpendicular to isobars
  • c)
    anti-clock wise
  • d)
    parallel to isobars
Correct answer is option 'C'. Can you explain this answer?

Alok Verma answered
If a low-pressure area forms in the atmosphere, air flows towards this region, but will be deflected perpendicular to its velocity by the Coriolis force. Instead of flowing straight towards the low pressure area, the air ends up circulating around it. 
This pattern of air flow is called a cyclone. In the Northern Hemisphere the direction of rotation around a low pressure area is counter-clockwise or anti-clockwise.

Prisha Tiwari answered
Satpura region

The Satpura range is one of the seven major mountain ranges in India. It stretches over an area of about 800 km, from the west to the east. The Satpura range is located in central India, covering parts of Madhya Pradesh, Maharashtra, and Gujarat.

Ranges in the Satpura region

The Satpura range is divided into three major ranges as follows:

1. Maikal range - located in the east
2. Mahadeo range - located in the central part
3. Barwani hills - located in the west

Correct sequence of ranges from West to East

The correct sequence of the ranges in the Satpura region from the west to the east is as follows:

Barwani hills - Mahadeo range - Maikal range

Explanation

The Barwani hills are located in the western part of the Satpura range, in the state of Gujarat. The Mahadeo range is located in the central part of the Satpura range, covering parts of Madhya Pradesh and Maharashtra. The Maikal range is located in the eastern part of the Satpura range, covering parts of Madhya Pradesh and Chhattisgarh.

Therefore, option 'A' which presents the correct sequence of the ranges in the Satpura region from the west to the east as Barwani hills - Mahadeo range - Maikal range is the correct answer.

Which of the following is NOT a Direct source for obtaining information about the interior of earth?
  • a)
    Volcanic eruption
  • b)
    Meteorites
  • c)
    Mines
  • d)
    All of the above
Correct answer is option 'B'. Can you explain this answer?

Meteorites are INDIRECT source of information about the Earth’s Interior.
  • Meteorites and Earth are born from the same nebular cloud. Thus, they are likely to have a similar internal structure.
  • When meteoroids fall to the earth, their outer layer is burnt during their fall due to extreme friction and the inner core is exposed.
  • The heavy material composition of their cores confirms the similar composition of the inner core of the earth. 
But because they are not from inside the earth, they act as an INDIRECT source of information due to similar composition.

In 1971, East Pakistan declared independence from Pakistan and became Bangladesh. Since then, India and Bangladesh have shared a friendly relationship and have been working together on various issues.

Importance of the Border

The India-Bangladesh border is important for several reasons. It is a porous border, which means that people and goods can easily cross the border. The border is also important for trade and commerce between the two countries.

The border is also important for security reasons. The border is guarded by the Border Security Force (BSF) on the Indian side and the Border Guards Bangladesh (BGB) on the Bangladesh side. The two forces work together to ensure that the border is secure.

Challenges of the Border

The India-Bangladesh border faces several challenges. One of the biggest challenges is illegal immigration. People from Bangladesh often cross the border into India illegally in search of better economic opportunities. This has led to tensions between the two countries.

The border is also used for smuggling of goods and weapons. The two countries are working together to combat these challenges and ensure that the border is secure.

Conclusion

In conclusion, the India-Bangladesh border is the longest border that India shares with any country. The border is important for trade, commerce, and security. While the border faces several challenges, the two countries are working together to ensure that the border is secure.

    Only 1 and 2
  • c)
    Only 1, 2 and 4
  • d)
    All of the above
Correct answer is option 'C'. Can you explain this answer?

Devansh Datta answered
  1. Jet stream is a current of fast moving air found in the upper levels of the atmosphere somewhere between 10-15 km above the earth’s surface: This statement is correct. Jet streams are fast-flowing, narrow air currents in the upper atmosphere that move at speeds of around 100-200 mph (160-320 km/h). They are typically found between 10-15 km above the Earth's surface, and are driven by large temperature differences between the polar regions and the tropics.
  2. The position of jet stream denotes the location of the strongest surface temperature contrast: This statement is also correct. Jet streams are associated with strong horizontal temperature gradients in the atmosphere. These gradients are caused by differences in the amount of solar energy received by different regions of the Earth's surface. Where these temperature gradients are strongest, the jet stream tends to be located.
  3. Winds of jet stream are stronger in summer than winter: This statement is incorrect. In fact, the winds of the jet stream are generally stronger in winter than in summer. This is because the temperature contrast between the polar regions and the tropics is typically greater in winter, which results in stronger temperature gradients and stronger jet stream winds.
  4. Jet streams generally blow from west to east: This statement is correct. Jet streams in the Northern Hemisphere generally flow from west to east, while those in the Southern Hemisphere flow from east to west. This is due to the rotation of the Earth, which causes the Coriolis effect and deflects the flow of air masses to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Consider the following statements:
Statement-I: Basalt is the primary rock type found in oceanic crust.
Statement-II: Basalt forms from slow cooling of magma at the surface.
Which one of the following is correct in respect of the above statements?
  • a)
    Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I
  • b)
    Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I
  • c)
    Statement-I is correct but Statement-II is incorrect
  • d)
    Statement-I is incorrect but Statement-II is correct
Correct answer is option 'C'. Can you explain this answer?

Explanation:

Statement-I: Basalt is the primary rock type found in oceanic crust
- Basalt is indeed the primary rock type found in oceanic crust. It is a dark, fine-grained volcanic rock that is formed from the rapid cooling of lava at the Earth's surface.
- Oceanic crust is primarily composed of basalt and is created at mid-ocean ridges through volcanic activity.

Statement-II: Basalt forms from slow cooling of magma at the surface
- This statement is incorrect. Basalt actually forms from the rapid cooling of lava at the surface, not from slow cooling of magma.
- Magma refers to molten rock beneath the Earth's surface, while lava is molten rock that has reached the surface.
Therefore, the correct answer is:
c) Statement-I is correct but Statement-II is incorrect

The channel also plays a crucial role in the defense of India as it serves as a gateway for foreign ships entering the Indian Ocean. The Indian Navy maintains a strong presence in the region to monitor any suspicious activities.

In conclusion, the Nine Degree Channel is associated with Lakshadweep Island, which is located in the Arabian Sea off the coast of India. It is a narrow sea passage that connects the islands to the Indian Ocean and is an important route for navigation, transportation, fishing, and defense.
