Milpa is the name given to shifting cultivation in Mexico and in the neighbouring parts of Central America, where maize, beans and squash are grown together on a patch cleared from the forest.

Strong heating at the equator makes the air expand and rise, so surface pressure is low and horizontal winds are weak; sailing ships were often becalmed there.

Hiralal Chaudhuri is called the father of the Blue Revolution, the sharp rise in India's fish production.

Basic lava is poor in silica, very hot and thin, so it travels a long way from the vent before it solidifies.

The Himalayas, about 2,400 km long, are divided from west to east into regions marked by river valleys, and the Nepal Himalayas lie between the Kali in the west and the Teesta in the east.

Air flows from where pressure is high to where it is low, and that moving air is what we call wind; the greater the difference in pressure, the stronger the wind.

The Deccan plateau is the large triangular block of the Peninsular plateau south of the Narmada, bounded by the Satpura and Vindhya ranges in the north, the Western Ghats in the west and the Eastern Ghats in the east, with an average height of about 600 metres.
