Do's' and don'ts' during earthquake are: Location Don'ts' At home Stand still near the corners of the house and sit under the table or any wooden furniture. Cut off the power supply at the time of an earthquake. Do not run here and there and create chaos. Do not stand below heavy objects such as wall clocks, decoration pieces, photo frames etc. In a vehicle or outside the house Park the car in an open area and sit inside it.

Find an open area away from tall building, trees or electric poles.

Do not stand near tall buildings, trees or electric pole. The construction of dams creates a huge water reservoir in which a large portion of land is submerged.

Thus, these dams cause excess water pressure in the micro-cracks and fissures in the ground near or under the reservoir. Due to this excess pressure, the water seeps into the ground and lubricates the rocks.

In the worst scenario, when the water pressure is very high, the water reaches the fault planes and lubricates them. This lubrication reduces friction between the tectonic plates, thereby causing the slipping of plates over one another.

Hence, in this way dams construction can trigger an earthquake. Page No Question 2: Give scientific reasons.

It is safer to find shelter under things like a bed, table at the time of earthquake. In Monsoons, don't take shelter near hillside. Any one theme of the following: IV. Forest Society and Colonialism: a Relationship between forests and livelihoods.

This allows the authorities to issue warnings and plan evacuation.

Artificial reservoirs should be built with sluice gates and sand bags should be used to block the flow of water.

Low grounds or viaducts can be created to carry water in a certain direction or underground. Trees should be planted in the catchment areas to stop soil erosion. DROUGHTS A drought is a period of below-average precipitation in a given region, resulting in prolonged shortages in its water supply, whether atmospheric, surface water or ground water.

It can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local economy.

These surface waters may dry out if the flow from their sources upstream is affected. Global Warming Even though some people do not accept that the average temperature of the earth has risen, it is on record that human actions have contributed to more greenhouse gasses in the atmosphere. As a result, there are warmer temperatures, often resulting in more dryness and bush fires often causing drought conditions.

EFFECTS OF DROUGHTS Diminished crop growth or yield productions and carrying capacity for livestock Dust bowls, themselves a sign of erosion, which further erode the landscape Dust storms, when drought hits an area suffering from desertification and erosion Famine due to lack of water for irrigation Habitat damage, affecting both terrestrial and aquatic wildlife Hunger, drought provides too little water to support food crops.

Desalination — of sea water for irrigation or consumption.

For instance, analysis of water usage in Yemen has revealed that their water table underground water level is put at grave risk by over-use to fertilize their Khat crop. Land use — Carefully planned crop rotation can help to minimize erosion and allow farmers to plant less water-dependent crops in drier years.

Earthquake: Protection Against Earthquake

Outdoor water-use restriction — Regulating the use of sprinklers, hoses or buckets on outdoor plants, filling pools, and other water-intensive home maintenance tasks. Rainwater harvesting — Collection and storage of rainwater from roofs or other suitable catchments. Recycled water — Former wastewater sewage that has been treated and purified for reuse.

Such disasters are caused by microorganisms that cause epidemics. These have spread due to man-made conditions.Related content. Each represents a different form of politics, and a specific combination of forces.
