The correct answer is: a) Earthquakes.
Mizoram is a state in northeastern India. It is located in the Indo-Myanmar Ranges, which are a part of the Himalayan mountain system. The state is seismically active, and has experienced several earthquakes in recent years. The most recent major earthquake in Mizoram was in 2016, with a magnitude of 6.8. The earthquake caused significant damage to infrastructure and buildings in the state.
Earthquakes are caused by the movement of tectonic plates. The plates are constantly moving, but they are not always moving at the same rate. When the plates move at different rates, they can grind against each other, causing the plates to stick together. This build-up of pressure can eventually cause the plates to break apart, releasing the energy that has been building up. This release of energy causes the earthquake.
The effects of an earthquake can be devastating. Earthquakes can cause buildings to collapse, roads to crack, and bridges to fall. They can also cause landslides and tsunamis. Earthquakes can also cause injuries and deaths.
There are a number of things that can be done to reduce the risk of earthquake damage. One is to build buildings that are designed to withstand earthquakes. Another is to develop early warning systems that can give people time to evacuate before an earthquake strikes. Finally, it is important to have a plan in place in case an earthquake does strike.
The other options are incorrect because they are not caused by the movement of tectonic plates. Tornadoes are caused by thunderstorms, forest fires are caused by dry weather and human activity, and droughts are caused by a lack of rainfall.
