SSC JE Geography Questions with Detailed Solutions

Correct Answer: (A) October and November

Explanation:

• The retreating monsoon or northeast monsoon occurs in India during the months of October and November.
• This phase marks the withdrawal of the southwest monsoon from the Indian subcontinent. The monsoon winds shift direction, and the rain-bearing winds come from the northeast, bringing rainfall mainly to the southeastern parts of India, particularly Tamil Nadu, Andhra Pradesh, and parts of Karnataka and Kerala.

Information Booster:

• The retreating monsoon is a transitional phase after the main monsoon season (June to September), during which the monsoon winds begin to retreat from the Indian subcontinent.
• The northeast monsoon brings important rainfall to the southeastern coastal regions, especially Tamil Nadu, where it is a crucial source of water for agriculture.
• While the southwest monsoon brings widespread rainfall, the northeast monsoon mainly affects the eastern coastal areas, leading to significant rainfall in places like Chennai and other cities in Tamil Nadu.

Correct Answer: (A) Pond

Explanation:

• A pond is a small, shallow freshwater body with calm water, typically smaller than a lake. It is often surrounded by land and may have plants growing in or around it.
• Ponds are generally calm and do not have strong currents, unlike rivers or lakes.

Information Booster:

• Lake: A large body of water, often deeper and larger than a pond, and may have a more significant water flow or currents.
• Lagoon: A shallow body of water separated from a larger body of water (like an ocean) by a barrier such as a sandbar or coral reef.
• River: A large, flowing body of water that usually has a strong current and moves across the land towards an ocean, sea, or lake.

Correct Answer: (B) Desertification

Explanation:

• Sahel is a region in Africa located south of the Sahara Desert. Over the last century, it has lost a significant portion of its productive land due to overgrazing, deforestation, unsustainable farming practices, and climate change.
• The process by which fertile land becomes arid and unproductive is known as desertification. This leads to reduced agricultural productivity and threatens the livelihoods of local communities.

Information Booster:

• Causes of Desertification in Sahel:
• Overcultivation and overgrazing of land.
• Deforestation for fuel and construction.
• Climate change, leading to prolonged droughts.
• Poor irrigation practices and soil mismanagement.
• Consequences:
• Loss of vegetation and biodiversity.
• Soil erosion and nutrient depletion.
• Migration of people due to scarcity of resources.
• Global Context: Desertification affects about 33% of the Earth's land surface and is a major environmental challenge, particularly in semi-arid regions like the Sahel.

Correct Answer: (C) Lonar

Explanation:

• Lonar Lake is located in Buldhana district of Maharashtra.
• It is a crater lake formed by a meteorite impact around 52,000 ± 6,000 years ago.
• Lonar Lake is famous for its unique saline and alkaline water and is considered a geological and ecological wonder.

Information Booster:

• Pushkar Lake: Located in Rajasthan, famous for the annual Pushkar Camel Fair.
• Dal Lake: Located in Srinagar, Jammu & Kashmir, known for its houseboats and scenic beauty.
• Bhimtal Lake: Located in Uttarakhand, it is a freshwater lake in the Nainital district.
• Significance of Lonar Lake:
• It is one of only four known hyper-velocity impact craters in basaltic rock on Earth.
• The lake attracts scientists, tourists, and bird watchers due to its unique ecosystem.

So, the lake in Buldhana district, Maharashtra is Lonar Lake.

The correct answer is (B) FTT.

Explanation:

• A. It is related to changes in temperature over several years – False. This statement is related to climate, not weather. Weather refers to the short-term atmospheric conditions in a specific place, whereas climate deals with long-term averages of weather conditions over many years, often spanning decades or centuries.
• B. It depends on the elevation of the region – True. Weather conditions can indeed depend on the elevation of a region. At higher elevations, the air is thinner and cooler, resulting in lower temperatures. For instance, the Himalayan region has cooler weather at higher altitudes than the plains below. Similarly, mountainous regions tend to experience different weather patterns compared to low-lying areas.
• C. It is related to temperature fluctuations within a day – True. Weather is concerned with daily fluctuations in atmospheric conditions such as temperature, humidity, and pressure. These fluctuations can change from morning to afternoon and night, especially in regions with large diurnal temperature ranges (e.g., deserts). For example, in desert regions, temperatures may drop drastically at night compared to daytime.

Information Booster:

• Weather vs Climate: While weather is the short-term atmospheric condition at a particular place (e.g., today’s temperature, humidity, and precipitation), climate refers to the average weather conditions over a long period (usually 30 years or more).
• Elevation and Weather: As elevation increases, the temperature generally decreases. For instance, mountain ranges like the Andes or Himalayas experience much colder weather than nearby coastal areas.
• Daily Temperature Fluctuations: Areas with high diurnal temperature variation experience significant changes in temperature between day and night. Desert climates are a classic example where daytime temperatures can soar, and nighttime temperatures can plummet.

The correct answer is (C) Ocean acidification weakens coral skeletons and affects shell formation.

Explanation:

• Ocean acidification occurs when the ocean absorbs excess carbon dioxide (CO₂) from the atmosphere, forming carbonic acid and lowering the pH of seawater.
• This leads to a reduction in carbonate ions, which are essential for corals and shell-forming organisms to build their skeletons and shells.
• As a result, coral skeletons become weaker and more fragile, and organisms like mollusks, clams, and some plankton species struggle to form shells.

Information Booster:

• Coral reefs are critical marine ecosystems, supporting biodiversity, protecting coastlines, and providing livelihoods to millions of people.
• Ocean acidification, combined with rising sea temperatures, contributes to coral bleaching and ecosystem decline.
• Long-term acidification can disrupt marine food chains, impacting fisheries and global food security.

Why other options are incorrect:

• A. Ocean acidification has no effect on coral reefs: Incorrect, as it directly affects calcification.
• B. Ocean acidification increases coral growth: Incorrect, it reduces growth and weakens skeletons.
• D. Ocean acidification increases coral biodiversity: Incorrect, it usually reduces biodiversity due to stress and mortality.

Correct Answer: (A) Luni

Explanation:

• The Luni River is the largest river system in Rajasthan.
• It originates from the Aravalli hills near Ajmer and flows southwest into the Thar Desert, eventually disappearing in the Rann of Kutch.
• It is a seasonal river, receiving water mainly during the monsoon season.

Information Booster:

• Length: Approximately 495 km
• Tributaries: Major tributaries include Sukri, Jojari, and Bandi rivers.
• Significance:
