Physical & Regional Geography

The region described in the passage is most likely experiencing an equatorial climate. * Clear and bright mornings with sea breeze: This suggests a warm and humid environment near the ocean. * Heat building up during the day: Equatorial regions receive strong, direct sunlight throughout the year, leading to high daytime temperatures. * Afternoon thunderstorms: The rising heat in the afternoon creates convection currents, leading to the formation of towering cumulonimbus clouds that bring brief, intense rain showers with thunder and lightning. * Short-lived rain: Equatorial regions experience frequent, short bursts of rain, followed by clear skies again.

The unique "Living Root Bridges" are found in Meghalaya, a state in northeastern India. These bridges are a testament to the ingenuity and sustainable practices of the Khasi and Jaintia tribes who inhabit the region. They train the aerial roots of specific tree species, like the Ficus elastica (Indian rubber tree), to grow and intertwine over time, forming strong and resilient bridges across rivers and streams.

In India, teak is a dominant tree species in Tropical Deciduous Forests. These forests are also known as "Monsoon Forests" and are characterized by: - Rainfall: They receive moderate rainfall, typically ranging from 70 to 200 cm annually. - Seasonality: They experience a distinct dry season, leading to trees shedding their leaves during this period. - Vegetation: Tropical Deciduous forests are home to a variety of trees, including teak, sal, shisham, and sandalwood.

Champaka - Central India (Incorrect): Champaka, also known as Chamba, was located in the present-day Himachal Pradesh region. Durgara - Jammu (Correct): Durgara corresponds to the present-day Jammu region. Kuluta - Malabar (Incorrect): Kuluta, also known as Kulu, was situated in the present-day Himachal Pradesh region, bordering Kullu Valley. Malabar refers to the southwestern coastal region of India. Therefore, only pair 2 is correctly matched.

Assessment of crop productivity: IRS satellites capture data that helps assess crop health, growth stage, and potential yield.
Locating groundwater resources: Remote sensing allows for studying geological features and identifying potential zones with underground water reserves.
Mineral exploration: IRS data can reveal signatures of specific minerals on the Earth's surface, aiding in mineral exploration activities.
Telecommunications: IRS satellites are not designed for telecommunication purposes. Geostationary satellites are typically used for this function.
Traffic studies: While remote sensing can be used for some traffic studies (e.g., analyzing transportation infrastructure), it's not the primary application of IRS satellites. Therefore, only 1,2 and 3 are primary applications of IRS satellites.

Statement 1 is incorrect: The Changpa community is not found primarily in Uttarakhand. They are mainly concentrated in the Changtang region, a high-altitude plateau that stretches across parts of Ladakh (India) and the Tibet Autonomous Region (China). Statement 2 is correct: The Changpa are traditionally semi-nomadic pastoralists. They are well-known for rearing Changthangi goats, a special breed known for their fine wool, also called Pashmina. This wool is prized for its warmth, softness, and luxury. Statement 3 is correct: The Changpa community is indeed recognized as a Scheduled Tribe in India. This classification provides them with certain social and legal protections under the Indian Constitution. Hence, statements 2 and 3 are correct.

The seasonal reversal of winds is the typical characteristic of a monsoon climate. Monsoons are seasonal winds that bring predictable patterns of rainfall. In summer, warm, moist air blows inland from the ocean, bringing heavy rainfall. In winter, the winds blow offshore, bringing dry conditions. This seasonal reversal of winds is what defines a monsoon climate.

Continental drift: The movement of continents over millions of years has led to changes in the distribution of landmasses, altering habitats and creating opportunities for species to migrate, adapt, and diversify. It has influenced speciation events by creating barriers to gene flow and promoting allopatric speciation. Glacial cycles: Fluctuations in global climate associated with glacial-interglacial cycles have had profound effects on ecosystems and species distributions. Periods of glaciation have resulted in the expansion and contraction of ice sheets, leading to changes in sea levels, habitats, and the distribution of flora and fauna. These environmental changes have driven evolutionary processes such as adaptation, migration, and extinction. Therefore, both continental drift and glacial cycles have played significant roles in shaping the evolution of organisms.

Statement 1 is correct: Oak trees are a common sight in the temperate forests of the Himalayas, particularly at mid-altitudes. Statement 2 is correct: Rhododendrons are a diverse group of flowering shrubs that thrive in the cool, moist conditions of the Himalayas. They are known for their vibrant blooms and are a characteristic feature of the Himalayan landscape. Statement 3 is incorrect: Sandalwood is not typically found in the Himalayas. It prefers drier climates and is more commonly associated with tropical regions like southern India.

Statement 1 is incorrect: Coal bed methane is indeed pure methane gas extracted from coal seams. However, shale gas is not a mixture of propane and butane only. Shale gas is primarily composed of methane, similar to coal bed methane, and can be extracted from fine-grained sedimentary rocks, specifically shale formations. So, the first part of the statement is correct, but the second part is incorrect. Statement 2 is incorrect: It's not accurate to say that no shale gas sources have been found in India. While it's true that coal-bed methane sources are abundant in India, shale gas sources have also been identified, although their exploitation is at a nascent stage compared to coal-bed methane. Therefore, neither of the statements is entirely correct.
