Seismic sea waves which approach the coasts at greater force arc known as – |
| A. | Tides |
| B. | Tsunami |
| C. | Current |
| D. | Cyclone |
| Answer» B. Tsunami | |
|
Explanation: A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, typically an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impadts and other disturbances above or below water all have the potential to generate a tsunami. Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide, and for this reason they are often referred to as tidal waves. |

Land and sea-breezes occur due to : |
| A. | Conduction |
| B. | Convection |
| C. | Radiation |
| D. | Tides |
| Answer» B. Convection | |
|
Explanation: During the day, the sun warming the land also warms the air. Since land heats up quicker than water does, the air over land gets warmer than the air over the water. Consequently, the warmer air, being less dense moves up. To fill its place the cooler air over the water moves in to fill its place creating what is known as a Sea Breeze. Reversely, at night the land cools down faster than the water does, and creates a Land Breeze. |

Hanging Valley is formed due to the action of – |
| A. | Glacier |
| B. | River |
| C. | Ocean |
| D. | Wind |
| Answer» A. Glacier | |
|
Explanation: A hanging valley is a tributary valley with the floor at a higher relief than the main channel into which it flows. They are most commonly associated with U-shaped valleys when a tributary glacier flows into a glacier of larger volume. The main glacier erodes a deep U-shaped valley with nearly vertical sides while the tributary glacier, with a smaller volume of ice, makes a shallower U-shaped valley. Since the surfaces of the glaciers were originally at the same elevation, the shallower valley appears to be 'hanging' above the main valley |
|

Mica is found in which one of the following pairs of rocks? |
| A. | Slate- Sandstone |
| B. | Schist-Gneiss |
| C. | Limestone-Sandstone |
| D. | Shale- Limestone |
| Answer» B. Schist-Gneiss | |
|
Explanation: The schists constitute a group of medium-grade metamorphic rocks, chiefly notable for the preponderance of lamellar minerals such as micas, chlorite, talc, hornblende, graphite, and others. Gneissic rocks are usually medium- to coarse-foliated and largely recrystallized but do not carry largequantities of micas, chlorite or other platy minerals. Mica minerals make some rocks sparkle! They are often found in igneous rocks such as granite and metamorphic rocks such as schist. Most schists are mica schists, but graphite and chlorite schists are also common. Schist is a crystalline metamorphic rock, mostly composed of more than 50% tabular and elongated minerals. |

The Mohorovicic (Moho) Discontinuity separates – |
| A. | Outer core and Mantle |
| B. | Inner and Outer core |
| C. | Sima and Nife |
| D. | Crust and Mantle |
| Answer» D. Crust and Mantle | |
|
Explanation: The Mohorovicic discontinuity, usually referred to as the Moho, is the boundary between the Earth's crust and the mantle. Named after the pioneering Croatian seismologist Andrija Mohorovicic, the Moho separates both the oceanic crust and continental crust from underlying mantle. The Moho mostly lies entirely within the lithosphere; only beneath mid-ocean ridges does it define the lithosphere - asthenosphere boundary. |
