Energy is the total power derived from natural resouces -- the sun, oceans, fossil fuels, wind, etc, and can be converted into electrical energy for the consumption of our needs and benefits.

The sources of energy are --

electrical energy, heat/ thermal energy, chemical energy, mechanical energy, nuclear energy, energy in the form of electromagnetic radiation - light.

The two major resources  of energy are -- 

1. Reneweable  resources -- The resources that can easily renewed( replaced), does not cause any pollution, are inexhaustible and cannot be affected by human activities are --  Air, water and solar energy, and the resouces undergoing research and development are -- solar, biomass, wind, biogas, tidal, geothermal.

2. Non - reneweable resources -- The resources, that cannot be easily renewed, causes pollution, easily exhaustible and mainly affected by human activities  are --  Mineral, Oil, Natural Gas, petroleum, Coal, water power.

There are four main components of Disaster Management Programme:

1) Minimizing or preventing any future emergency: This can happen in two ways.i.e, either you can reduce the chance of an emergency happening in future or you can reduce the damage of an unexpected or unavoidable emergency. For example: Buying an insurance for your home.

2) Preparation: It includes the plans or preparation made for rescue operations in case of an emergency or disaster. For example: Evacuation, Food and water availability.

3) Response: It's nothing but executing the plan you have prepared in case an emergency occurs. For example: seeking a safe place to hide during an earthquake.

4) Recovery: Recovery includes the actions taken to bring everything back to normal after a disaster or emergency. For example: claiming your insurance after your home caught fire.

The biosphere is the narrow zone of the earth comprising  of both living (biotic) and non- living( abiotic) orgamisms provoding them with energy and nutrients, and  where  the soil, water and air combine to survive life.  The biosphere extends from  the deepest root systems of the trees, the deep ocean trenches, the lush rainforests  to the high mountains. As such, it plays a critical role in the maintenance of ecosystems -- the existence of species and their reciprocal interactions, and is also critical for climate regulation as well.

Biodiversuty thrives within ecosystems, and the biosphere is a reliable source of food on Earth.

In early 1870, the United Nations estabished a project -- Man and Biological Programme (MAB) so to promote a sustainable development, a working, balanced relationship between people and the natural world.

The biological reserves are -- 

1. Yagambi, the fertile Congo River Basin, supports activities -- agriculture, hunting and mining, and is home to 32,000 species of wildlife and tree plantations.

2.  Yayu, Ethiopia, has been developred for agriculture, cultivation of plantations -- fruits, honey and timber, and is the main producer of  Coffea Arabica -- the coffee shrub.

In subsistence farming, the farmer used to grow the crops for their consumption basically the don't hire members from outside whereas the commercial farming the farmer cultivate crops on a large scale for commercial purposes

Resources are extremely precious for the mankin. We should respect and preserve our resources but we indiscriminately use our resources it would create an acute problem for not only our green planet but also to flora and fauna.The outcomes would be depletion of ozone layer, leaching of soil, emission of toxic gases,soil degradation,water crisis,global warming,loss of biome and many adverse effects.

The term folding in geography can be defined as the upper layer fold on the crust due to internal pressure upward to the top. Folding can be inwards or outwards,as it is permanent in nature, the great Himalaya is the best example of folding.

Longitudinal valleys between the lesser Himalayas and shiwaliks are known as ' duns' in the West and' duars' in the east

1. presence of high water level

2. absence of hard, rocky grounds

3. soil needs to be loosly bound, porous

4. low lying aeas instead of steep slopes 

Mineral oilcan have positive effects on dry skin Mineral oil is used to treat constipation

Warm and humid climate is best for jute cultivation. It needs temperature of 27°-35°C. Water logging and constant rain is very harmful for jute cultivation. Alluvial soil type is best for jute cultivation along with Sandy loam and clay loams. West Bengal, Assam and Bihar are the top most jute growing states. Country's 95-97% jute belongs from here.
