 SECTION – B

18. Read the following passage and answer the questions that follow:

     Tropical deciduous forests are also called the monsoon forests. Tropical deciduous forests are found in areas receiving 70 to 200 cm of annual rainfall Monsoon forests grow over the Sahyadris, the north-eastern parts of the peninsula, middle and lower Ganga valley and along the foothills of the Himalayas in the Shiwaliks, the Bhabar and the Terai. Sal, teak, shisham, sandalwood, khair etc. are important trees. These trees provide useful wood and are economically very important. They shed their leaves in the beginning of summer season in the face of water shortage and are called deciduous forests. They are 30 to 45 meters tall and cover about 20% of our forest area.  

1. What is another name of Tropical Deciduous Forests?

2. How much rain fall receiving by Tropical Deciduous Forests?

3. Name some important tree are grow in Tropical Deciduous Forests?

Answers:

1.Monsoon forests

2. 70 to 200 cm of annual rainfall

3. Sal, teak, shisham, sandalwood, khair

Question 19

1.Arrange correct sequence of different layers of the atmosphere from the surface of the Earth to upwards.

Answer:

  1. Troposphere
  2. Stratosphere
  3. Mesosphere
  4. Thermosphere
  5. Exosphere

2.Which layer of atmosphere is vital for telecommunications?

Answer:

Ionosphere

Explanation:

While the question doesn’t explicitly mention the Ionosphere, it is a crucial layer for telecommunications. The Ionosphere is a part of the Thermosphere that contains electrically charged particles. These particles reflect radio waves, enabling long-distance radio communication.

 3.What do you mean by tropopause?

Answer:

The tropopause is the boundary between the Troposphere and the Stratosphere. It is characterized by a significant decrease in temperature with increasing altitude and a change in the lapse rate (rate of temperature decrease). The tropopause acts as a barrier between the weather-driven Troposphere and the more stable Stratosphere.

 SECTION – C

Question 20:

Differentiate between Systematic approach and Regional approach.

Answer:

Systematic Approach:

  • Focuses on studying individual elements of the Earth’s surface (e.g., landforms, climate, vegetation, soil) in a systematic manner.
  • Aims to understand the underlying principles and processes governing these elements.
  • Involves a global or universal perspective.
  • Example: Studying global climate patterns, tectonic plate movements, or soil formation processes worldwide.

Regional Approach:

  • Focuses on studying the unique characteristics and interactions of various elements within a specific region.
  • Aims to understand the spatial and temporal variations of phenomena within that region.
  • Emphasizes the regional context and interrelationships between different elements.
  • Example: Studying the unique climate, vegetation, and landforms of the Amazon rainforest or the Himalayas.

Question 21:

Describe the factors that cause variations in insolation.

Answer:

Insolation, or incoming solar radiation, varies across the Earth’s surface due to several factors:

  1. Angle of Incidence: The angle at which the Sun’s rays strike the Earth’s surface. At higher latitudes, the Sun’s rays are more oblique, spreading over a larger area and resulting in less intense insolation. At lower latitudes, the Sun’s rays are more direct, resulting in higher insolation.

  2. Earth’s Rotation: The Earth’s rotation causes day and night. During the day, a particular location receives direct sunlight, while at night, it receives no direct sunlight.

  3. Earth’s Revolution: The Earth’s revolution around the Sun in an elliptical orbit leads to variations in the distance between the Earth and the Sun, which affects the intensity of insolation.

  4. Tilt of the Earth’s Axis: The Earth’s axis is tilted at an angle of 23.5 degrees. This tilt causes seasonal variations in insolation. During summer in the Northern Hemisphere, the North Pole is tilted towards the Sun, resulting in longer days and more intense insolation.

  5. Atmospheric Absorption and Scattering: The Earth’s atmosphere absorbs and scatters some of the incoming solar radiation, reducing the amount of insolation reaching the surface.

Question 22:

How are Tides caused? Explain their importance.

Answer:

Tides are the periodic rise and fall of sea levels caused by the gravitational pull of the Moon and, to a lesser extent, the Sun.

  • Gravitational Pull: The Moon’s gravitational pull exerts a stronger force on the side of the Earth facing it, causing a bulge of water. A smaller bulge occurs on the opposite side of the Earth due to the Earth’s inertia.
  • Sun’s Influence: The Sun also exerts a gravitational pull on the Earth, contributing to the tides. When the Sun, Moon, and Earth are aligned (during new moon and full moon), their gravitational forces combine to produce spring tides, which have higher high tides and lower low tides. When the Sun and Moon are at right angles to each other, their gravitational forces partially cancel each other out, resulting 1 in neap tides, which have lower high tides and higher low tides.
  • Importance of Tides:
  • Navigation: Tides influence navigation by affecting water depths in harbors and channels.
  • Fishing: Tides affect the movement of fish, influencing fishing activities.
  • Tidal Power: Tidal energy can be harnessed to generate electricity.
  • Coastal Erosion and Deposition: Tides play a significant role in shaping coastlines through erosion and deposition of sediments.
  • Ecological Significance: Tides influence the distribution of marine organisms and their habitats.

Question 23:

Why there is a difference of two hours in local time between Arunachal Pradesh and Gujarat?

Answer:

The Earth rotates on its axis from west to east. As the Earth rotates, different parts of the Earth pass through sunlight at different times. This creates a difference in local time across longitudes.

  • Arunachal Pradesh is located in the easternmost part of India, while Gujarat is located in the western part of India.
  • As the Earth rotates from west to east, the Sun rises earlier in Arunachal Pradesh compared to Gujarat.
  • For every 15 degrees of longitude, there is a time difference of one hour.
  • The approximate longitudinal difference between Arunachal Pradesh and Gujarat is around 30 degrees.
  • Therefore, there is a difference of approximately two hours in local time between Arunachal Pradesh and Gujarat.

Question 24:

Who has given the concept of Continental Drift Theory? Write about the evidences which were given in the support of Continental drift

Answer:

Alfred Wegener proposed the Continental Drift Theory in 1912.

Evidences supporting Continental Drift:

  1. Fit of the Continents: The coastlines of South America and Africa appear to fit together like pieces of a jigsaw puzzle, 1 suggesting they were once connected.  

     

  2. Fossil Evidence: Identical fossils of plants and animals have been found on continents now separated by vast oceans, indicating that these landmasses were once joined.

  3. Geological Evidence: Similar rock formations and mountain ranges are found on continents that are now far apart, suggesting they were formed under similar conditions when they were connected.

  4. Paleoclimate Evidence: Glacial deposits and evidence of tropical climates have been found in areas that are now far from the poles and the equator, respectively, suggesting that the continents were once located in different positions.

Question 25:

Name the erosional and depositional features formed by the action of river and diagrammatically explain one land features of each.

Answer:

Erosional Features:

  1. V-shaped valleys: Formed by the downward cutting action of the river.
  2. Waterfalls: Formed when a river flows over a steep cliff.
  3. Gorges: Deep, narrow valleys formed by the river cutting through resistant rock.
  4. Potholes: Circular depressions formed by the swirling action of pebbles and stones in the river bed.

Depositional Features:

  1. Floodplains: Flat, fertile land formed by the deposition of sediments during floods.
  2. Deltas: Fan-shaped deposits of sediments formed at the mouth of a river.
  3. Meanders: Loop-like bends in the river channel formed due to erosion on the outer bank and deposition on the inner bank.
  4. Oxbow Lakes: U-shaped lakes formed when a meander is cut off from the main river channel.

Diagram (Example – V-shaped valley):
