Scientists who investigate weather phenomenon are called meteorologists. To study a particular feature, may require an observation from a larger area. By combining great number of observations and analysing them by computers it is possible to get information about a large weather system. Satellites..

It is fifth most abundant element in Earth's crust. It is found existing as whole mountain ranges of limestone, marble and chalk, in vast sedimentary rocks of CaCO 3 . Other important minerals containing calcium are gypsum (CaSO 4 .2H 2 O), anhydrite (CaSO 4 ), fluorite (CaF 2 ..

Geological Resources - Large number of industries is established in the course of development of human society - based on vast geological resources. Most geological resources are the basis of industrial development and improvement of human life styles. Entire mankind depends on geological sources s..

Composition of Air - For thousands of years, air was considered to be a mixture of many gases. The true composition of air was not known for a long time. Air is a mixture of various gases. The main gases present in air are nitrogen (78.1% by volume) and oxygen (20.9% by volume). These two gases tog..

Introduction - Biogeography reveals that living organisms (plants and animals) are found practically everywhere on this earth. The living components interact among themselves as well as with their physical environment like soil, air and water. The branch of biology, which deals with the r..

Concept of a Point Object - A real object can rotate as it moves. For example, a cricket ball may be spinning while it is moving, as a whole, in a trajectory. Also, a body may vibrate as it moves, for example, a falling water droplet. These complications can be avoided by considering the ..
