• Cotopaxi: is the highest volcano in the world. It is situat¬ed in Ecuador.
• Dust Devil: is a dusty whirlwind normally a few feet in diameter and about 100 feet tall, sometimes also wider and higher. 
• Earth mass: The mass of the earth is about 81 times that of the moon. 
• Earth’s core: is mainly composed of iron and nickel. Lithosphere is the innermost layer of the earth. 
• El Nino: is the weather phenomenon brewing in the tropical Pacific Ocean. It is the largest climate event of the 20th century setting off more global disasters than ever before. El Nino is warming of the waters off Equatorial South America which causes climate abnor¬malities around the world. The impact can be flooding drought in California, Brazil, Africa and Australia, severe storms in the Central Pacific and a decline in hurricanes hitting the south-eastern United States. 
• Exfoliation: This type of weathering is common both in the cold as well as in the hot cli¬mate regions. 
• Great Circle: A circle on the earth’s surface whose plane passes through its centre, and bisects it into two hemispheres. Two opposing meridians together form a Great Circle. The shortest distance between any two points on the earth’s surface is the arc of the Great Circle which passes through them. 0° latitude forms a Great Circle. (The latitude or longi¬tude 75°W should be combined with 75°E to obtain the Great Circle). 
• Horse Latitudes: Sub-trop¬ical belts of high atmospheric pressure over the oceans situat¬ed in both hemispheres. These are called Belts of Calm between regions of the Trade Winds and Westerlies of higher latitudes. 
• Hydroponics: means culti¬vation of the plants without use of soil. 
• Hyetology: is the study of rainfall. 
• Kandla: is a sea port situat¬ed at the head of the Gulf of Kuch in Gujarat State.
• Lapse Rate: is the rate of change in temperature with increase of altitude. 
• Laterite soils: Laterite soils are formed by the weathering of laterite rocks. These can be dis¬tinguished from other soils by their acidity. 
• Loams (loamy soil): Amix¬ture of sand, clay and silt is known as loamy soil. Loams are formed where the soils have equal proportion of sand, silt and clay. 
• Local winds and their areas: Khamsin—Egypt; Zonda—Argentina; Santa Ana—California; Simoon—Iran. 
• Mansarover Lake: is in Tibet. Near it, the rivers having their source are the Brahamputra, the Sutlej and the Indus. 
• Maoris (Tribes): are the original inhabitants of New Zealand.
• Nutrification: is the process of conversion by action of bacteria, of nitrates in the soil.
• Pangong Tso: is one of the world’s highest and brackish lakes in Jammu & Kashmir.
• Proxima Centauri: is a star nearest to the earth.
• Roaring Forties: are west¬erly winds.
• Selvas: The rain forest of Amazon basin is called Selvas. These are rainy tropical forests.
• Spring Tides: are caused when the sun and the moon are in a straight line. The tide on its maximum height is known as Spring Tide.
• Tsunamis: are huge sea waves caused by earthquakes.
• Willy Willy: is a tropical cyclone of the north-west Australia.
