Answer 1

1. Plastic - Insulator

Plastics are excellent insulators and they efficiently trap heat. Hence they are used as handles for pans.

They don't have free electrons moving around. So, They don't conduct Heat or Electricity.

2. Earthquake - Sudden shaking of Earth

Sudden shaking of Earth's Lithosphere releases Energy that creates Seismic waves.

Smaller Earthquakes are caused by Volcanic Activity, Landslide, Mine blasts and nuclear experiments.

Larger Earthquakes occur naturally.

3. Tsunami - Earthquake under Sea

Earthquake under Sea pushes up powerful waves that trigger Tsunami. Bigger Earthquakes move large volume of water disturbing water pressure and creating Huge Waves above.

4. Copper - Lightning Conductor - Transfer of Charge to Earth

Lightning conductors protect tall buildings by diverting the current from non-conducting parts of the structure to a path of least resistance to the Earth through cables.
