An earthquake is a sudden shaking of the ground. It can happen anywhere at any time. Let’s learn about why earthquakes happen and how we can stay safe during one!
- It is when the earth shakes or moves suddenly.
- Earthquakes happen because of movements in the earth’s plates under the ground.
- They can happen in many places around the world, especially near fault lines (cracks in the earth’s surface).
- Drop to the ground, cover your head, and hold onto something strong during an earthquake.
- Have an emergency kit ready with food, water, and first-aid supplies. Know where to go for safety.
- Earthquake Alerts Some places give warnings before an earthquake, but it’s important to always be prepared.

3. Which of these is NOT a type of earthquake boundary?
a) Convergent boundary
b) Divergent boundary
c) Transform fault
d) Tornado fault
Answer: d) Tornado fault
Explanation: Tornado fault is not a type of earthquake boundary. The three types are convergent, divergent, and transform boundaries.

Answer: b) To protect yourself during the shaking
Explanation: “Drop, cover, and hold on” is a safety method used to protect yourself from falling objects during an earthquake.
5. What is the purpose of securing heavy items in your home before an earthquake?
a) To prevent your furniture from moving
b) To avoid injuries from falling objects
c) To make your house look neat
d) To stop the items from making noise

7. What is the instrument used by scientists to measure earthquake intensity?
a) Thermometer
b) Barometer
c) Seismograph
d) Microscope
Answer: c) Seismograph
Explanation: A seismograph is used by scientists to measure and record the intensity of earthquakes.
8. What can happen after an earthquake that you should be prepared for?
a) Hurricanes
b) Tornadoes
c) Aftershocks
d) Floods
Answer: c) Aftershocks

Why do buildings fall in earthquakes?
Buildings fall during earthquakes due to ground shaking that causes structural damage. Poor construction, weak materials, and lack of reinforcement increase the risk of collapse.
What causes earthquakes?
Earthquakes are caused by the sudden release of energy in the Earth’s crust. Tectonic plate movements, fault lines, and volcanic activity generate these powerful ground shakes.
Why do earthquakes happen?
Earthquakes happen when stress builds up along fault lines. When the stress is released, it causes ground shaking, resulting in an earthquake that can cause damage.
