Answer 1

Answer:

Good afternoon ❤️

Explanation:

1. During thunderstorm, when a charged cloud passes over an uncharged cloud, uncharged cloud acquires opposite charge by induction and the two clouds attract. When they combine with each other, they produce a large amount of heat, light and sound also known as lightning.
2. Lightning strikes dissolve unusable nitrogen in water and form a natural fertilizer which is absorbed by the roots of plants. Thus, lightning helps for nitrogen fixation. 2. Lightning also produces important gas called ozone which protects our planet from the harmful UV rays.
3. An earthquake is caused by a sudden slip on a fault. ... When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate.
4. Stay away from trees, poles and any metallic objects. Squat on the ground with your head between your knees. If you are inside your house or a building, then avoid using any electrical appliances or using running water (since water is a good conductor of electricity).

4. ANSWER

• If you are outside, stay away from buildings, trees, and power lines. Stay close to the ground.
• If you are at home, sit under a strong table or bed. Stay away from objects that may fall in case the tremors increase.
• Stay off the roads. If you're outside, move away from buildings which can collapse. Stay in an open area where there are no trees, buildings or power lines. If you're driving when an earthquake strikes, pull over to a large open area that's not under trees or power lines.
• If you are inside your house or a building, then avoid using any electrical appliances or using running water (since water is a good conductor of electricity).
