Mention two measures for protection from Tsunami.

AskMedha’s AI teacher
Model answer · preventive measures, Tsunami
- 1.One measure for protection from Tsunami is that mangrove forests should be conserved in coastal areas. These mangrove bushes along the coast help to reduce the speed of the Tsunami waves and thus lessen the destruction caused when the waves strike the coast.1 mark
- 2.Another measure for protection from Tsunami is that the coastal population should be made aware of Tsunami so that they know how to act when it strikes. Along with this, early warning systems for disaster management should be made effective so that people and fishermen can be warned and moved to safer places in time.1 mark
- Write 'mangrove forests should be conserved' and 'reduce the speed of tsunami waves' in the first point.
- Write 'coastal populations should be made aware' and 'early warning systems for disaster management should be made effective' in the second point.
- Keep each measure in its own paragraph, one measure per point.

AskMedha’s AI teacher
Model answer · building shape, earthquake prevention
- 1.The shape of buildings in earthquake-prone areas should be rectangular and symmetrical, and these buildings should be of light structure so that they can withstand earthquake shocks.1 mark
- 2.The building plan should be simple and symmetrical, and the building should be of light structure, so that it is built on earthquake resistant techniques to minimise the destruction caused by the earthquake.1 mark
- Write the words "rectangular" and "symmetrical" for the shape of the building.
- Mention "light structure" and "simple" plan to cover both points.
- Do not add other preventive measures like forecast or administrative work, as the question asks only about the shape of buildings.

What should be the shape of buildings in the earthquake prone area ?
Medha Ma’am
AskMedha’s AI teacher
Model answer · building shape, earthquake safety
- 1.The shape of buildings in earthquake-prone areas should be rectangular. This shape helps the building to withstand the shocks of the earthquake waves better than other shapes.1 mark
- 2.The building plan should be simple and symmetrical so that it can withstand the earthquake shocks. A simple and symmetrical plan reduces the chances of damage and collapse during the vibrations of an earthquake.1 mark
- Write the word 'rectangular' clearly for the shape of the building.
- State that the plan should be both 'simple' and 'symmetrical' to withstand earthquake shocks.
- Do not add extra details like forecast, seismograph or disaster management as the question asks only about building shape.

What do you mean by focus and epicentre of earthquake ?
How the model answer begins
1. Focus is the place beneath the surface of the earth where the vibration of the earthquake originates. It is the point of origin where seismic waves are generated.
