Q Answer Why
1 (d) The inner core is the innermost, solid iron-nickel layer of the Earth.
2 (a) The Mohorovicic discontinuity separates the crust from the mantle.
3 (b) Continental collision at convergent boundaries uplifts fold mountains like the Himalaya.
4 (b) The Richter scale gives earthquake magnitude (energy); Mercalli gives intensity.
5 (b) Granite is an intrusive igneous rock; the others are sedimentary.
6 (c) Direct vapour-to-ice change is deposition (a form of sublimation in common usage).
7 (b) The ozone layer lies in the stratosphere.
8 (b) In the troposphere temperature falls with height (normal lapse rate).
9 (b) Trade winds blow from the subtropical highs towards the equatorial low.
10 (b) Tsunamis are usually caused by submarine earthquakes (and sometimes landslides).
11 (c) Cumulonimbus clouds bring thunderstorms, lightning and heavy rain.
12 (a) Temperature inversion means temperature rises with height in a layer.
13 (b) The Dead Sea has among the highest salinity of any water body.
14 (b) Corals thrive in warm, shallow, clear, saline tropical waters.
15 (c) The Pacific is the largest and deepest ocean.
16 (b) Spring tides occur at new and full moon when Sun, Moon and Earth align.
17 (c) Solar energy is renewable; coal, oil and gas are fossil fuels.
18 (b) India's major coalfields lie in the Damodar valley (Jharkhand-West Bengal).
19 (b) Andhra Pradesh (Nellore belt) is the leading crude-mica producer; Jharkhand (Koderma) and Rajasthan are the other main producers. Verify the latest.
20 (a) Jet streams flow in the upper troposphere near the tropopause.
21 (a) Carbon dioxide is the largest contributor to anthropogenic warming by volume.
22 (a) Marble is metamorphosed limestone; the others are igneous or sedimentary.
23 (b) "Monsoon" derives from Arabic "mausim", meaning season.
24 (b) Lake Baikal in Siberia is the world's deepest freshwater lake.
25 (b) A barchan is a crescent-shaped, mobile sand dune.
