Step 1: Understanding Tsunami.
A tsunami is typically caused by underwater earthquakes, volcanic eruptions, or underwater landslides. These events cause sudden tremors or movements inside the sea, which generate massive waves.
Step 2: Analyze each option.
- (A) Strong winds: Strong winds can cause storms or hurricanes but are not directly related to tsunamis.
- (B) Excessive rain: While heavy rainfall can lead to floods, it is not related to the formation of a tsunami.
- (C) High temperature: High temperatures are not a cause of tsunamis, though they can influence weather patterns.
- (D) Tremors inside the sea: This is correct. Underwater seismic activity such as earthquakes or volcanic eruptions causes tsunamis.
Step 3: Conclusion.
The correct answer is (D) Tremors inside the sea, as it directly leads to the formation of tsunamis.
Final Answer:
The correct answer is (D) Tremors inside the sea.
