the climate resources and physical features of an area

. They are useful in showing areas of diseased and healthy vegetation. Healthy plants appear red. Young plants show bright red while those ready for harvesting appear dark red. Plants affected by drought and disease can be identified by the different color of their images compared with th..

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 ..

Polar orbits are used to watch the earth. They are the planes perpendicular to equatorial plane. Satellites in polar orbit are low enough to collect the information about earth in detail. Low earth orbit is the easiest and cheapest to reach, lying just above the atmosphere a few hundred miles up...

"Remote Sensing" - can be defined as obtaining information about an object by observing it from a distance and without coming to actual contact with it. Infact when we see an object and understand what it is, our eye is sensing that object remotely. This is a broad definition. But we generally use ..

Summary - Current through a given area of a conductor is the net charge passing per unit time through the area. To maintain a steady current, we must have a closed circuit in which an external agency moves electric charge from lower to higher potential energy. The work done per ..

Impact of Misuse of Natural Resources - Natural resources characteristically exhibit two features. They are: 1) Physical limitations 2) Limitations of regeneration / production. Natural physical resources like geophysical, hydro-geological..

Summary - Environment refers to the natural elements that make up the earth and surround living organisms The abiotic or physical aspects of the environment refer to elements like air, soil, water etc. The biological or biotic components of environment are the plants and animals Natural h..

Everything that we use or consume - food, clothes, vehicles, tools, petrol, furniture, medicines, books, toys, and the infrastructure of electricity, roads bridges, and buildings are obtained from resources on this earth. The only thing one gets from outside is the sun's energy and even ..

Forests are the most important resource of our globe. Naturally formed forests are found in such parts of globe - where the factors of plant growth have been ideal for several centuries. For this reason, they are mostly found in regions of high rainfall and regions of high altitude. The u..
