Answer: By locating words hidden horizontally, vertically, or diagonally in the given word grid, we find names of natural disasters such as Earthquake, Flood, Tornado, etc.
In simple words: Natural calamities are hidden inside the letter grid, which we can find by reading across or down.

Exam Tip: Always check rows left-to-right and columns top-to-bottom systematically when solving word search puzzles.

Que2. Identify the natural calamity and write two lines on it:
Answer:
1. First Image: Forest Wildfire
- It is an uncontrolled fire that burns in wildland areas, destroying forests, wildlife, and homes.
- It spreads very quickly due to dry weather and strong winds.
2. Second Image: Tornado
- A tornado is a violently rotating column of air that touches the ground, often shaped like a dark funnel.
- It can uproot trees, destroy buildings, and cause severe damage in its path.
In simple words: The first picture shows a forest fire and the second picture shows a tornado. Both are dangerous natural disasters.

Exam Tip: Identify visual cues like flames in forests for wildfires and swirling funnel clouds for tornadoes.

Que3. Identify the statement whether it is true or false. If it is false make it true.
1. In earthquake fire comes out from the interior of the earth. False
Answer: False. In a volcanic eruption, molten lava and fire come out from the interior of the earth, whereas an earthquake is the shaking of the ground caused by movements under the earth's crust.
In simple words: Fire and lava come out during volcanoes, not earthquakes.

Exam Tip: Distinguish between the effects of volcanoes (lava/fire) and earthquakes (shaking/tremors).

2. If there is no rain, crops can fail and there can be a drought. True
Answer: True. Lack of rainfall over a long period leads to water scarcity, drying up of soil, failure of crops, and drought conditions.
In simple words: Without rain, plants cannot grow and water dries up, causing a drought.

Exam Tip: Remember that drought is directly linked to prolonged absence of rain.

In simple words: Famines are caused by a severe lack of food, not heat.

Exam Tip: Famine means extreme scarcity of food leading to starvation.

4. Tsunami affects the fishermen most. True
Answer: True. Since a tsunami is a series of massive ocean waves caused by underwater earthquakes, it directly strikes coastal areas and heavily affects fishermen, their boats, and their livelihoods.
In simple words: Tsunamis happen in the ocean and destroy coastal areas where fishermen live and work.

Exam Tip: Connect tsunamis with oceans and coastal populations.

Que4. Complete the table:
