It is caused by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of different types of land and water, it absorbs the sun's heat at different rates. During the day, the air above the land heats up more quickly than the air over water. The warm air over the land expands and rises, and the heavier, cooler air rushes in to take its plac.
Millions of years ago, the remains of plants and animals decayed and built up in thick layers. This decayed matter from plants and animals is called organic material it was once alive.

Pressure and heat changed some of this organic material into coal, some into oil petroleum , and some in.
Mount Everest is the highest mountain in the world. Its elevation of 29, feet 8, meters was detonated using GPS satellite equipment on May 5, The National Geographic Society has confirmed the new elevation.
Climate change is likely to threaten all life forms on earth including plants and animals. The degree of sensitivity will, however, vary from one species to the other. Changes in temperature and perceptive patterns will affect several weather sensitive sectors like agriculture, forestry, water resources and coasts. The impact of these changes will also be felt on human systems affecting human heal.
An agricultural region is defined as an area having homogeneity in relief, soil type, climatic conditions, farming practices, crops produced and crop association.
India is endowed with diverse agro-climatic conditions capable of producing almost all kinds of agricultural produce in one or the other region. Several scholars have attempted to delineate the agricultural regions of India, the promi. On a scale from Right to Left, right being absolute anthropocentric and the left being the realm of eco-terrorists, I would say that I fall somewhere just to the left of middle.
I am a businessman and I believe that profit is number one. I am a citizen of this planet and I strongly believe that drastic measures must be taken to protect it. To most people the preceding statements seem contradictory. Land, a non-renewable resource, is central to all primary production systems.
Over the years, the country's landmass has suffered from different types of degradations. Degradation of land is caused by biotic and abiotic pressures. An ever-increasing population places enormous demands on land resources. This is particularly acute in India, which has only 2. A landslide is the rapid sliding of large masses of bed rocks or regoliths.
Whenever mountain slopes are steep there is a possibility of large disastrous landslide. Landslides are triggered by earthquakes or sudden rock failures. They can also result when the base of a slope is over steepened by excavation or river erosion.
Severe earthquakes in mountainous regions are a major cause of landslid. Drought can occur in any area regardless of the amount of rainfall the area may receive or irrespective of its scientific and social advancement, it can occur in small pockets or over a large area.
Drought can occur at any time and cause scarcity of water for drinking, irrigation, industry and urban needs. Drought causes deficiency in soil moisture and makes the land unproductive. The human impact on natural environment is one of the most pressing issues of contemporary times and a subject of discussion.
In geographical literature, the ways in which human beings have changed and are changing the face of the earth and the human role in the natural processes and systems have drawn the attention not only of natural scientists but also of social scientists as well as of plan. In India grasslands are found in wet soils, in salt belt and in the hilly region. There are 60 species of perennial grasses, which make up the fragile ecosystem that supports our cattle.
Pastures and grasslands are spread over an area of about Other grazing lands are found under tree crops and groves, on wastelands and fallow lands which cover 3. The removal of soil by running water and wind is known as soil erosion. The soil-forming process and the erosional process of running water and wind are continuous. Generally, there is a balance between these two processes. The rate of removal of fine particles from the surface is the same as the rate of addition of particles to the soil layer.
Sometimes such a balance is disturbed by natural o. The Himalayan and the Alpine mountain building process is now better explained with the help of the Theory of Plate Tectonics. This theory has replaced the former geosynclinals theory of mountain building.
The marine environment of seas and oceans is large, occupying 70 per cent of the earth's surface. The volume of surface area of marine environment lighted by the sun is small in comparison to the total volume of water involved. This and the dilute solution of nutrients limit production. It is deep, in places nearly more than 6 kilometers. All the seas are interconnected by currents, dominated b. As a lake fills with silt it changes gradually from a deep to a shallow lake or pond, then to a marsh, and beyond this, in some cases, to a dry-land forest.
When a crop field is deserted or a forest is severely burned over, it is just like a plot of bare ground and a series of plant communities grow up there and replace one another- first annual weeds, then perennial weeds and grasses, then shrubs.
In organisms all metabolic processes necessary for life start at a certain minimum temperature and increase with rise in temperature until they reach the maximum level at a temperature called optimum temperature. Further rise in temperature beyond optimum brings about decrease in metabolic rate, until it ceases at a temperature called maximum temperature thus, the favorable temperature range fo.
The individual organisms of species population, in order to grow and multiply, must be supplied with certain essential materials. Of the hundred four i. These are called essential elements. Several other elements are needed in small q.
The aquatic environment is subject to water movements rang-ing from small vertical circulations to strong currents. The streams have a unidirectional movement and in seas the movement is rever-sible.
Environmental Science is a substantive and active field through which systematic research is performed. It is an amalgamation of several disciplines and because of it being interdisciplinary it becomes possible to solve the intricate issues of the environment.
It also helped develop certain environmental laws through which various environmental investigation protocols were established. Environmental Science has also helped establish a trend of public awareness towards the threats of climate change caused by environmental problems. We are now going to write an essay on one of the topics mentioned above so that you can understand how to research and put your piece together. Just so you know, our next guide focuses on: Food security basically assures the continuation of access to food, regardless of race or class, at all times for the sake of a healthy life.
The number of people that die from starvation, dietary deficiencies or malnutrition throughout the world sits at a staggering 18 million. Population growth needs to be kept in check if food security is to be achieved. Other factors tying into food security include the availability of water, active farming, equal distribution and reasonable consumption of food. It is very important that small scale farmers are properly incentivized so that the culture of farming continues to thrive.
The international community also needs to come together to ease trade related restrictions. Long term food security can be achieved through protecting and conserving wild crop variants in wildlife sanctuaries and national parks. Environmental scientists are currently working on a second green revolution so that food security is assured for the future.
Some people think that this cannot be changed, while others believe actions can be taken to bring about a change. It is often said that governments spend too much money on projects to protect wildlife, while there are other problems that are more important? Some people think the best way to solve global environmental problems is to increase the cost of fuel. Some people think an international car-free day is an effective way to reduce air pollution.
Others think there are more effective ways do to this. While some people consider global warming to be the most pressing environmental problem which we have at the moment, others believe that deforestation has a more devastating impact on our world. The government should reduce the amount of money spent on local environmental problems and instead increase funding into urgent and more threatening issues such as global warming.
