Answer the following questions:------
1. What are the conditions during a cyclone?
2. What should the administrative agencies of a town or village do after cyclone?
3. Name the items that one should keep in an emergency kit during an earthquake.
4. What are avalanches? Name the areas in India that are affected by avalanches.
5. How are floods caused?
Answers
Answer:
1)There are six main requirements for tropical cyclogenesis: sufficiently warm sea surface temperatures, atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to sustain a low pressure center, a preexisting low level focus or disturbance, and low vertical wind
3)•Water - one gallon of water per person per day
for at least three days, for drinking and sanitation.
•Food - at least a three-day supply of non-perishable food.
•Battery-powered or hand crank radio and a NOAA Weather Radio with tone alert.
•Flashlight.
•First aid kit.
•Extra batteries.
4)Avalanches Prone Areas in India
the snowy regions of Jammu and Kashmir, Himachal Pradesh and Western Uttar Pradesh.
5)Flooding occurs most commonly from heavy rainfall when natural watercourses do not have the capacity to carry excess water. However, floods are not always caused by heavy rainfall. In coastal areas, water inundation can be caused by a storm surge as a result of a tropical cyclone, a tsunami or a high tide coinciding with higher than normal river levels. If a dam fails, triggered for example by an earthquake, the downstream area will flood, even in dry weather conditions.
Other factors which can contribute to flooding include:
volume, spatial distribution, intensity and duration of rainfall over a catchment
the capacity of the watercourse or stream network to carry runoff
catchment and weather conditions before rainfall
ground cover
topography
tidal influences.
2) I DON'T KNOW
Answer:
1. The condition during a cyclone are:-
i. strong winds can a uproot trees, electricity lines etc.
ii. heavy rainfall can cause flood.
iii. tidal waves can cause serious damage to life and property.
2. the Indian meteorological department is responsible for the tracking ,forecasting and warming about the cyclone it has established several centres in the country and has advanced technology to forest and warned about cyclones.
3. the item that one should keep in an emergency kit during an earthquake are:-
* such as bottled drinking water,non perishable food, first aid kit torch light and battery operated radio with extra batteries.
4. avalanches are the sliding of snow cover from the slopes of mountain due to gravity.
some regions of Himalayas, particularly the Western Himalayas.
* jammu and kashmir : higher reaches of Kashmir,gurez valley Kargil and Ladakh.
* himachal pradesh: chamba,kuller Spiti and kinnaur.
* Western Uttar Pradesh parts of tohri garhwal and Chamoli district.
5.flood are caused in many different ways:-
1. overflowing of a river
2. snowmelt
3. storm surges
4. short is intense flash floods.
