Q: What are the advantages and disadvantages of building dams?
Q: Explain with examples the difference between primary and secondary effects of natural disasters.
Answers
Answer:
Here's your answer .
Explanation:
- Fracking involves drilling wells in shale deposits, then pumping in water and other additives at high pressure to break the rock and release trapped oil. In some regions fracking can trigger earthquakes by causing faults in the rock to slip.
- The two basic steps in preventing forest fires are reducing risk and reducing hazard. ... Hazard is reduced by compartmentalizing a forest with firebreaks (alleyways in which all vegetation is removed) and reducing the buildup of fuel (litter, branches, fallen trees, etc.) by controlled burning.
- With the assistance of hydroelectricity or hydroelectric power, electricity is generated at a steady rate.
- For the use of another time, water is preserved.
- For irrigation purposes, water sports or even other types of pleasurable activities, the lake or reservoir built behind the dam may also be used.
- Primary Effects occur as a result of the process itself. For example water damage during a flood or collapse of buildings during an earthquake, landslide, or hurricane. Secondary Effects occur only because a primary effect has caused them.

Answer:
- What is fracking? How can it induce a natural disaster?
》 Fracking involves drilling wells in shale deposits, then pumping in water and other additives at high pressure to break the rock and release trapped oil.
The fluid that is injected at depth is sometimes hydraulically connected to faults.
2. What is the controlled burning method? How does it reduce the risk of forest fires?
》Controlled burning, also known as prescribed burning, involves setting planned fires to maintain the health of a forest.
clearing up the working place from any flammables 10 to 25 feet around; avoiding the use of heating and spark-producing equipment near dried-up vegetation.
3.What are the advantages and disadvantages of building dams?
》 Advantages of dams-
- With the assistance of hydroelectricity or hydroelectric power, electricity is generated at a steady rate.
- With the assistance of hydroelectricity or hydroelectric power, electricity is generated at a steady rate.For the use of another time, water is preserved.

4. Explain with examples the difference between primary and secondary effects of natural disasters.
》 Primary effects-
- Primary Effects occur as a result of the process itself.
- Primary Effects occur as a result of the process itself. For example water damage during a flood or collapse of buildings during an earthquake, landslide, or hurricane.
Secondary effects-
- Secondary Effects occur only because a primary effect has caused them.
- Secondary Effects occur only because a primary effect has caused them.the onset of a tsunami wave, or a landslide. ... The Tohoku earthquake of 2011 is a key example.
