Second grade geography. Cheat dad's geography teacher. Quietly ask heaven, float away with the lid. QAQ

1, there are more than 20 kinds of meteorological disasters, mainly including the following:

(1) rainstorm: mountain torrents, river flooding and urban water accumulation;

(2) Rain and waterlogging: waterlogging;

(3) Drought: drought in agriculture, forestry and grassland, and water shortage in industry, cities and rural areas; Meteorological disaster

(4) Dry-hot wind: dry-hot wind and foehn wind;

(5) High temperature heat wave: extreme heat and high temperature, human diseases, burns, and crop ripening;

(6) Tropical cyclones: gale, rainstorm and flood;

(7) Cold damage: crops, livestock and fruit trees are harmed by strong cooling and low temperature;

(8) Freezing injury: frost, crop and livestock freezing injury, water pipes and oil pipes freezing injury;

(9) Freezing rain: wires, branches and roads are frozen;

(10) Freezing: rivers, lakes and seas freeze, and roads freeze after rain and snow;

(1 1) Snow damage: snowstorm, snow;

(12) Hail disaster: destroying crops and houses;

(13) Wind disaster: falling trees, reversing houses, reversing cars and reversing boats;

(14) Tornado: local destructive disaster;

(15) Lightning: lightning casualties;

(16) Continuous rain (lewd rain): it is not conducive to crop growth and development, grain mildew, etc.

(17) dense fog: human diseases and traffic jams;

(18) low-altitude windshear: aviation accident;

Just find 4-5 common words.

Geological disasters refer to disasters that occur in the earth's lithosphere, including earthquakes, volcanoes, mudslides, collapses and landslides.

2. There are mainly rainstorm, drought, smog, typhoon, waterlogging, freezing rain and blizzard.

3. There are mainly earthquakes, landslides, mudslides and collapses.

4. I don't know if it counts: collapse, dam break, acid rain, red tide, pollution.

5, the general principle is: "safety first, prevention first, prevention is more important than robbery, be prepared."

The flood control plan includes three parts: preparation before flood season, work during flood season and work after flood season. Pre-flood preparations include: training flood control personnel; Check flood control engineering facilities to eliminate hidden dangers; Formulate flood control plans; Prepare enough flood control materials; Establish and improve flood forecasting and early warning system. The work in flood season includes: keeping abreast of meteorological and hydrological conditions, forecasting water conditions and issuing alarms when necessary; Patrol flood control projects, use various measures of flood control system, control and dispatch floods according to water conditions, engineering conditions and flood control dispatching scheme, and immediately rush to protect them in case of danger; Emergency measures (such as flood diversion and evacuation of residents in flood diversion areas, etc.) in case of over-standard flood. ) Take it after asking the superior for approval to reduce losses. After the flood season, check the flood control works and flood control work, and sum up experiences and lessons; Strengthen the emergency rescue project; If emergency measures such as flood diversion are taken, the aftermath should be done well.

6. This one is quite long. You can choose it.

A. If you are indoors, you should hide under solid furniture nearby, such as desks, solid beds and rural heatable kang, or you can hide in corners or small-span bathrooms, kitchens and other places with many pipes and good integrity. Be careful not to hide under the window of the external wall, in the elevator room, and not to jump off the building. These are very dangerous.

B. If you are in the classroom, you should hold your head under the guidance of the teacher, close your eyes and crouch under the desk quickly. As soon as the earthquake stops, evacuate quickly and orderly, and don't crowd when evacuating.

C. If you are in a theater, a stadium or a restaurant, you should quickly lie under your seat with your head in your hands. You can also hide under the stage or orchestra pit; The audience at the gate can quickly run out of the gate or the stadium.

D If you are outdoors, try to stay away from narrow streets, tall buildings, tall chimneys, transformers, glass curtain wall buildings, viaducts and places where dangerous goods and inflammables are stored. After the earthquake stops, don't run back to the collapsed building easily to prevent aftershocks from hurting people.

E. If you are in a department store, you should hide near pillars or large commodities, but try to avoid glass cabinets. When you are upstairs, you should seize the opportunity to gradually move to the bottom.

F. If you are in the workshop of a factory, you should crouch near large machine tools and equipment, but pay attention to leaving dangerous places such as power supply, gas source and fire source.

G. If you are in a moving car, tram or train, you should grasp the handrails to avoid falling and bumping, and at the same time, you should pay attention to personal injury caused by falling luggage. People facing the luggage direction can lean on the chair in front with their arms to protect their heads and faces; People with their backs to luggage can protect the back of their heads with their hands, raise their knees to protect their stomachs and tighten their bodies. After the earthquake, get off the bus quickly and move to the open area.

H no matter where you hide, try to protect your head with a quilt, pillow, schoolbag or other soft objects, which is equivalent to putting on a soft helmet for yourself.

7. Debris flow prevention and control measures: divide the dangerous area and potential dangerous area of debris flow or divide the sensitivity of debris flow disaster; Strengthen the hydrometeorological forecast, especially the local rainstorm forecast in small areas. Local residents should always pay attention to disaster warning and forecasting, choose escape routes and avoid being caught off guard.

Emergency points: If you find signs of debris flow, you should immediately observe the terrain and run to the slopes or highlands on both sides of the valley. When you run away, you should abandon everything that affects your running speed. Don't hide under the steep hillside with rolling stones and a lot of deposits. Don't stay in low-lying places, and don't climb trees to escape.

Landslide prevention: "early detection, prevention first;" Find out the situation and comprehensively manage it; Strive for a radical cure, leaving no future trouble "principle, combined with the factors of slope instability and the internal and external conditions of landslide formation, from the following main aspects to control landslides:

A, increase the slope gradient.

B, eliminate and reduce the harm of surface water and groundwater, plan drainage facilities according to the site conditions, improve the surface drainage system around the slope, and discharge rainwater in time.

C, clean up the stone earthwork accumulated within the close range of the top of the slope, reduce the pressure on the top of the slope, and prevent the collapse and landslide caused by excessive bearing pressure on the top of the slope.

8. I really can't find this.
