Question 1

Consider the following statements:
1) The body waves are the last to report on seismograph.
2) These waves are more destructive than surface waves
3) P-waves vibrate parallel to the direction of the wave. This exerts pressure on the material in the direction of the propagation.
Which of the above is/are correct?

Question 2

Which of the following is not true regarding the mantle of earth?
1) The mantle extends from Moho’s discontinuity to a depth of 2,900 km
2) The crust and the uppermost part of the mantle are called aesthenosphere.
3) Aesthenosphere is considered to be the main source of magma that finds its way to the surface during volcanic eruptions.

Question 3

Consider the following about plate boundaries:
1) Subduction zones are the sites where the plates move away from each other.
2) Transform faults are the planes of separation generally perpendicular to the mid oceanic ridges.
Choose the correct statement(s):

Question 4

With reference to the thermal metamorphism, consider the following statements.
I. In Contact metamorphism the rocks come in contact with hot intruding magma and lava and the rock materials recrystallise under high temperature.
II. Quite often new materials form out of magma or lava are added to the rocks.
Choose the incorrect statement.

Question 5

Choose the correct statement(s):
1) Indirect gravitational stresses activate wave and tide induced currents and winds.
2) Without gravity and gradients there would be no mobility and hence no erosion, transportation and deposition are possible

Question 6

Consider the following statements:
1) Water vapour, a variable gas in the atmosphere, increases with altitude.
2) It may account more for dry and cold areas of desert and polar region than the warm and wet tropics.
3) It also absorbs parts of the insolation from the sun and preserves the earth’s radiated heat.
Choose the correct statement(s):

Question 7

Assertion: The lower concentration of dust particles is found in subtropical and temperate regions.
Reason: Due to dry winds in comparison to equatorial and polar regions.
Choose the correct option:

Question 8

Which of the following is true regarding troposphere?
1) Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents.
2) All changes in climate and weather take place in this layer.
3) This is the most important layer for all biological activity.

Question 9

Consider the following for spatial distribution of Insolation at the Earth’s Surface:
1) Maximum insolation is received over the Equator.
2) Generally, at the same latitude the insolation is more over the continent than over the oceans.
3) In winter, the middle and higher latitudes receive less radiation than in summer.
Which of the above is/are correct?

Question 10

Choose the incorrect statement(s):
1) A long winter night with clear skies and still air is ideal situation for inversion.
2) Over polar areas, temperature inversion is normal throughout the year.
