The answer is subduction zone, this describes the action of
having one slide and another plate beneath and merge into the mantle of the
earth. This usually happens when collision occurs such as having tectonic plates
collide of each planet.
Answer:
Rank of the stars from shortest to longest distances:
Barnard's Star (M4)
61 Cygnia A (K5)
Alpha Centauri A (G2)
Sirius (A1)
Spica (B1)
Explanation:
The habitable zone, also known as the circumstellar habitable zone, is the range of distances from a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.
The location of a star’s habitable zone is dependent upon its luminosity, which is the amount of light emitted by an object in a unit of time, because a star’s luminosity increases with time; and also the star's mass.
The inverse square law of light brightness can be used to determine the extent of the habitable zones for different luminosity stars with the formula:
star boundary = Sun boundary × squareroot[(star luminosity)/(Sun luminosity].
To reduce vulnerability, organisations such as the United States Geological Survey (USGS), governments and charities need to do the following.
Reduce the impact of hazard
Monitoring tectonic activity using equipment may help predict and identify major events. In addition to this, setting up evacuation zones and hazard mapping are helpful techniques to reduce the impact of a hazard.
Build capacity to cope with the hazard
Educating people about what to do, and having regular earthquake drills, are helpful in building capacity to cope. In addition, having well equipped emergency service teams who are well trained also increases a country’s ability to cope. Buildings can also be designed in a way to better survive earthquakes. From skyscrapers in San Francisco, USA, to new community centres in Kali Jawi, Indonesia, buildings can be made earthquake proof.
Tackle the root cause of the vulnerability
Governments and organisations can help reduce the vulnerability by actively trying to reduce inequality and poverty in countries. Everyone, regardless of wealth, should have the same status and right to protection.
