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.

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.

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.

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.
