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.
Lava and other materials that are launched from a volcano into the air are referred to as tephra. The correct option among all the options given in the question is option "A".Tephra is actually the material that is ejected by an active
volcano irrespective of the type of the material, fragment size or emplacement
mechanism. The airborne substances of the volcanoes are known by the name
pyroclasts. The pyroclasts remain as tephra unless they become hot enough to
fuse together.
The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.
Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.
Answer:The term cryosphere is used to describe the frozen part of the hydrosphere, such as glaciers and ice caps.
