“They are characterised by eruptions of cooler and more viscous lavas often resulting in explosive eruptions. Large quantities of pyroclastic material and ashes find their way to the ground along with the Lava.”
Above phase describes which of the following Volcanoes?
Correct
Correct Answer: B
Explanation
Composite Volcanoes: These volcanoes are characterised by eruptions of cooler and more viscous lavas than basalt. These volcanoes often result in explosive eruptions. Along with lava, large quantities of pyroclastic material and ashes find their way to the ground. This material accumulates in the vicinity of the vent openings leading to formation of layers, and this makes the mounts appear as composite volcanoes.

Consider the following statements regarding the distribution of the Rain:
1. Between 45 degree and 65 degree N and S of equator, the rain increases towards the east on the continents.
2. Between 35 degree and 40 degree N and S of the equator, the rain is heavier on the western coasts.
Which of the statements given above is/are correct?
Correct
Correct Answer: D
Explanation
Both the statements are incorrect. In general, as we proceed from the equator towards the poles, rainfall goes on decreasing steadily. The coastal areas of the world receive greater amounts of rainfall than the interior of the continents. The rainfall is more over the oceans than on the landmasses of the world because of being great sources of water. Between the latitudes 350 and 400 N and S of the equator, the rain is heavier on the eastern coasts and goes on decreasing towards the west. But, between 450 and 650 N and S of equator, due to the westerlies, the rainfall is first received on the western margins of the continents and it goes on decreasing towards the east. Both the statements are reversed. .

Consider the following statements:
1. An Earthquake can be predicted by detecting the P waves.
2. S waves propagate through a material by alternately compressing and expanding the medium.
3. P waves can travel through solid, liquid and gaseous medium.
Which among the above statement is/are correct?
Correct
Correct Answer: A
Explanation
Primary(P) Waves: These are primary waves and travel at the greatest velocity through the Earth. These are similar to sound waves. These are least destructive among 3 waves. They travel through gaseous, liquid and solid materials. (Statement 3 is correct) These waves are also called Longitudinal waves, Compressional waves or Pressure waves. They propagate through a material by alternately compressing and expanding the medium. Since P waves are less destructive and reach the surface first, we can predict the earthquake by detecting the P waves. (Statement 1 is correct)
Secondary S-waves: These are shear waves or shaking waves, are transverse waves that travel slower than P-waves. S-waves can travel only through solid materials. This characteristic of the S-waves is quite important. It has helped scientists to understand the structure of the interior of the earth. The direction of vibrations of S-waves is perpendicular to the wave direction in the vertical plane. (statement 2 is Incorrect) These waves are similar to the light waves.

3. Moho discontinuity lies between the upper and lower mantle.
Which of the statements given above is/are correct?
Correct
Correct Answer: C
Explanation
Crust: This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. It is brittle in nature. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly composed of basalt. Continental crust is less dense, thicker, and mainly composed of granite. Statement 1 is Incorrect while Statement 2 is correct. The mean thickness of oceanic crust is 5 km whereas that of the continental is around 30 km. The continental crust is thicker in the areas of major mountain systems. It is as much as 70 km thick in the Himalayan region. The crust is separated from the mantle by Moho discontinuity. Statement 3 is Incorrect.

With reference to Thermohaline circulation, consider the following statements:
1. It refers to the continuous replacement of seawater at depths with water from the surface.
2. It drives warmer surface waters polewards from the tropics.
3. It is faster than the wind-driven circulation of surface ocean currents.
Which of the statements given above is/are correct?
Correct
Correct Answer: A
Explanation
• Statements 1 and 2 are correct. Thermohaline circulation, also called Global Ocean Conveyor or Great Ocean Conveyor Belt, the component of general oceanic circulation controlled by horizontal differences in temperature and salinity. It continually replaces seawater at depth with water from the surface and slowly replaces surface water elsewhere with water rising from deeper depths. Although this process is relatively slow, tremendous volumes of water are moved, which transport heat, nutrients, solids, and other materials vast distances.
• Thermohaline circulation also drives warmer surface waters poleward from the subtropics, which moderates the climate of Iceland and other coastal areas of Europe.
• The general circulation of the oceans consists primarily of wind-driven ocean currents. These, however, are superimposed on the much more sluggish circulation driven by horizontal differences in temperature and salinity-namely, thermohaline circulation.
• Wind-driven circulation, which is strongest in the surface layer of the ocean, is the more vigorous of the two and is configured as large gyres that dominate an ocean region. In contrast, thermohaline circulation is much slower, with a typical speed of 1 centimetre (0.4 inch) per second, but this flow extends to the seafloor and forms circulation patterns that envelop the global ocean. Hence, statement 3 is incorrect..

At the same latitude, land surface becomes warm and cold more quickly than the water surface, because
1. Specific heat of water is much less than that of the land surface.
2. Redistribution of heat by conduction is slower in land surface than water.
Which of the statements given above is/are correct?
Correct
Correct Answer: B
Explanation
• Statement 1 is incorrect. Statement 2 is correct.
• Water is a slow conductor of heat, thus it needs to gain more energy than the sand or dry land in order for its temperature to increase. On the other hand, soil loses its heat much faster.
• Statement 1 is incorrect. The specific heat capacity (the amount of heat needed to raise the temperature of one gram of the substance by 1 degree) of water is much greater than the land because the relative density of water is much lower than that of the land surface. It means more heat is required to raise the temperature of one gram of water by 1 degree than one gram of land.
• Since land doesn’t circulate very rapidly, only the portion that is under direct sunlight absorbs solar radiation and that heat is then transported. Water, on the other hand, constantly circulates, so heat is transported by both radiative and circulative processes.

Consider the following statements regarding Mountains:
1. Fold mountains are created where two or more of Earth’s tectonic plates are pushed together.
2. Great African Rift valley and Rhine Valley (graben) and Vosges mountain (horst) in Europe are fold mountains.
3. Aravali is an example of residual mountain which was formed due to folding.
Which among the above statements is/are correct?
Correct
Correct Answer: B
Explanation
Fold mountains: These are created where two or more of Earth’s tectonic plates are pushed together. Statement 1 is correct. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges. Most fold mountains are found on the edge or former edge of continental plate boundaries Some of the fold mountains are the Himalaya, the Alps, the Rockies etc. Aravali once was a fold mountain. It is one of oldest fold mountain in the world which is now left in residual form. Statement 3 is correct.
Block Mountains: Block mountains are formed due to upward movement of the middle block between two normal faults . The up-thrown block is also called horst. Block mountains may be formed when the side blocks of two faults move downward whereas the middle block remains stable at its place. Block mountains may be formed when the middle block between two normal faults moves downward. Thus, the side blocks become horsts and block mountains. Ex- Great African Rift valley and Rhine Valley (graben) and Vosges mountain (horst) in Europe.Statement 2 is Incorrect.
