Parallels shrink as they move towards the poles, so the 0° parallel, the Equator, is the longest of all. Parallels of latitude are circles drawn parallel to the Equator.

The Umaria coalfield lies in the Umaria district of Madhya Pradesh, not in Jharkhand. Most of India's coal is Gondwana coal, found in the valleys of the Damodar, Son, Mahanadi, Godavari and Wardha rivers.

The Tropic of Cancer (23.5°N) passes through eight Indian states, and Manipur is not one of them; it lies just to the north.

Salt crystal growth breaks rock by pressure alone, without changing its minerals, so it is a type of physical (mechanical) weathering.

Arabica, Robusta and Liberica are the main species of the coffee plant, Coffea, grown around the world. Arabica (Coffea arabica) gives a milder, more aromatic coffee and grows best on cool hill slopes at higher altitudes.

All three features, richness in lime, iron, magnesia and alumina, a deep clayey and impermeable texture, and a spread over Maharashtra, Madhya Pradesh and Gujarat, describe the black or regur soil.

The lithosphere is the rigid outer shell of the Earth, made of the crust and the uppermost, solid part of the mantle.

Parallels of latitude are circles drawn parallel to the equator, and they grow shorter as one moves towards the poles, until a pole is a point with no length at all.

The correct answer is B, the Ten Degree Channel, which lies roughly along the parallel of ten degrees north and separates the Andaman group in the north from the Nicobar group in the south; Little Andaman lies to its north and Car Nicobar to its south.

It flows south along the west coast of North America, carrying cold water from higher latitudes towards the equator. As a rule, currents moving from the poles towards the equator are cold, and those moving from the equator towards the poles are warm.

India's territorial waters, where it has full sovereignty, extend 12 nautical miles (about 22.2 km) from the baseline of its coast.

Soil scientists list parent material, topography (relief), climate, biological activity and time as the factors that form soil; where people live is not one of them.

This is the order of the layers of the atmosphere from the ground upwards, with the exosphere above them all.

The exact, absolute position of any point on Earth is fixed only where its line of latitude crosses its line of longitude.

A crater is the bowl-shaped depression at the top of a volcano, around the opening through which lava, gas and ash come out.

A pull factor is something attractive at the destination that draws people towards it, and better pay is the classic example.

The atmosphere is heated mainly from below, by the long-wave heat the Earth's surface gives off, not directly by sunlight.

In this last stage both the birth rate and the death rate are low, so the population grows very slowly or stays almost steady.

The exosphere, the outermost layer of the atmosphere, is made up mostly of the two lightest gases, hydrogen and helium.

Groundwater is fed by rain that soaks into the ground, so how far a place lies from the coast does not by itself decide how much groundwater it has.
