Test: Natural Calamities - 1 - Class 5 MCQ

• An earthquake happens when the Earth's crust shakes due to movements deep inside the Earth.
• These movements can be caused by the shifting of large sections of the Earth called tectonic plates.
• Earthquakes can damage buildings and sometimes cause other natural disasters like tsunamis or landslides.

• A hurricane is a strong storm that forms over warm ocean water.
• It has very fast winds, heavy rain, and can cause floods in coastal areas.

• Floods happen when heavy rain causes rivers or lakes to overflow.
• This can lead to water covering land where it normally does not, damaging homes and roads.

• A landslide occurs when a large amount of rocks and soil suddenly moves down a hill or slope.
• Landslides can be caused by heavy rains or earthquakes.

• Tsunamis are large waves caused by underwater disturbances such as earthquakes, landslides, or volcanic eruptions.
• They can cause significant damage to coastal areas, and can be particularly dangerous because they can travel long distances from the source of the disturbance.

• Tornadoes are funnel-shaped clouds that form over land and are usually accompanied by strong winds and heavy rain.
• They can be extremely dangerous and can cause significant damage to buildings and infrastructure.

The correct answer should simply be Volcanic eruption (D), which encompasses the release of ash, gas, and molten material during such an event.

• Icebergs are large masses of ice that break off from glaciers and float in the sea.
• They can be dangerous for ships and other vessels that are traveling in the area, and can also have an impact on the climate and ecosystem of the surrounding area.

• A natural calamity is a disaster that is caused by natural phenomena such as floods, earthquakes, cyclones, and landslides.
• These disasters cannot be controlled or prevented by humans.

While fires can be caused by natural events such as lightning strikes, they are typically not considered natural calamities because they are often caused by human actions such as carelessness or arson.

• Floods are a type of natural calamity that is caused by an overflow of water.
• This can occur due to heavy rainfall, melting snow, or the overflow of rivers and lakes.

• Earthquakes are caused by the movement of the earth's tectonic plates.
• When these plates move, they can cause the ground to shake, resulting in damage to buildings and other structures.

• Cyclones are a type of natural calamity that is caused by high-speed winds.
• These winds can cause damage to buildings and other structures, and can also result in flooding due to heavy rainfall.

• Volcanic eruptions are a type of natural calamity that are caused by the release of molten rock, ash, and gas from a volcano.
• These eruptions can cause damage to buildings and other structures, as well as result in landslides and tsunamis.

• A landslide is a type of natural calamity that is caused by the sudden movement of a large mass of rock or earth down a slope.
• This can be triggered by heavy rainfall or seismic activity.
