3. There are different discontinuities within the Earth’s internal structure. Which are the discontinuities that have been incorrectly matched with its/their respective locations?

  1. Mohorvic discontinuity — boundary between Core and Mantle.
  2. Wiechert-Gutenberg discontinuity — boundary between Crust and Mantle.
  3. Conrad discontinuity – located at a depth of 15-20kms from the Earth’s surface.

Choose the correct code from the following.

  1. 1, 2 only.
  2. 2, 3 only.
  3. 3 only.
  4. 2 only.

 

4. Consider the statements regarding Earth’s interior and seismic waves.

  1. Primary waves totally disappear in the core region revealing that outer core is made up of liquid.
  2. Secondary waves show changes in its speed as it travels from magma chamber to lithosphere region indicating difference in density.
  3. The speed of secondary waves is highest inside the Earth’s Core region indicating highest density in the Core region.

Choose the correct statement/s from the code below.

  1. 1, 2 only.
  2. 2 only.
  3. 1, 3only.
  4. 2, 3 only.

 

5. Earth experiences seasons in a rhythmic fashion.

What are the causative factors?

  1. Rotation of the Earth on its own axis.
  2. Revolution of the Earth in its orbit around the Sun.
  3. Spherical shape of the Earth.
  4. Earth’s tilted axis.
  5. Axial parallelism.

Choose the correct code from the following.

  1. 1, 2 only.
  2. 1, 2, 3 only.
  3. 1, 2, 4, 5 only.
  4. All the above.

 

6. Winter solstice for Northern Hemisphere generally is on 22nd or 21st December every year.

Consider the statements regarding winter solstice in Northern Hemisphere.

  1. The circle of illumination excludes the North Pole region from Sunlight.
  2. From 66.5 degree South to 90 degree South, the Sun remains below the horizon the entire day.
  3. Arctic Circle is the Southernmost parallel in the Northern Hemisphere that experiences a 24 hour period of darkness on this day.

Choose the correct statements from the codes below.

  1. 1 only.
  2. 1, 3 only.
  3. 2 only.
  4. None of the above.

 

7. Paleomagnetism is the past magnetism of Earth stored in a rock.

Which among the following type of rocks provides most reliable readings of magnetism at a particular time?

  1. Igneous rocks.
  2. Sedimentary rocks.
  3. Metamorphic rocks.
  4. All the above rock types are equally reliable.

 

8. Earth’s magnetosphere is the area around the Earth where the geomagnetic field stretches out into space. Consider the following statements regarding magnetosphere.

  1. It is uneven in shape as it stretches largely towards the Sun because of Sun’s magnetic field.
  2. Solar winds can have influence on the Earth’s magnetosphere.
  3. This sphere deflects the charged particles that approach the Earth’s surface.

Choose the correct statement/s from the following codes.

  1. 1, 2 only.
  2. 2, 3 only.
  3. 1, 3 only.
  4. All the above.
