Question 1
Which of the following is/are not true?
1) The continental slope is the shallowest part of the ocean typically ends at a very steep slope, called the shelf break.
2) Massive sedimentary deposits received over a long time by the continental slopes, become the source of fossil fuels.
3) Canyons and trenches are observed in continental slope region.

Question 2
Consider these statements:
1) The temperature of surface water decreases from the equator towards the poles because the amount of insolation decreases poleward.
2) The oceans in the northern hemisphere receive more heat than the oceans in the southern hemisphere.
3) The enclosed seas in the high latitudes record relatively higher temperature than the open seas; whereas the enclosed seas in the low latitudes have lower temperature than the open seas.

Question 3
With reference to the prevailing wind over the ocean, consider these:
1) The winds blowing from the land towards the oceans results in the upwelling of cold water from below.
2) It results into the longitudinal variation in the temperature.
Which of the above is/are correct?
1) The winds blowing from the land towards the oceans results in the upwelling of cold water from below.
2) It results into the longitudinal variation in the temperature.
Which of the above is/are correct?
Question 4
Choose the correct statement(s):
1)Thermoclineis the boundary region, from where there is a rapid increase of temperature.
2) About 90 per cent of the total volume of water is found below the thermocline in the deep ocean.

Question 6
Consider these statements:
1) The horizontal motion of ocean water refers to the ocean currents, waves and tides.
2) When the tide is channeled between islands or into bays and estuaries, they are called tidal currents.
3) The ‘tide-generating’ force is the difference between two forces; i.e. the gravitational attraction of the moon and sun.
