During an earthquake, what is the most destructive type of seismic wave that caused a rolling motion?
1. P waves
2. S waves
3. Surface waves
4. Transverse waves
Answer:
Surface Waves
Explanation:
Surface waves cause more damage because they produce more ground movement and travel slowly, which makes it take longer to pass.
During an earthquake, the most destructive type of seismic wave that caused a rolling motion is known as a Surface wave. Thus, the correct option for this question is C.
What is an Earthquake?An earthquake may be defined as a sudden trembling of the surface of the earth. It causes great destruction, as a result of movements within the earth's crust or volcanic action. The circumstance of an earthquake is fatal to living organisms.
According to the context of this question, surface waves are those waves that significantly cause more threats to the surface of the earth. they effectively construct more ground trembling and movement. These waves travel gradually and this makes it take longer to pass.
Therefore, during an earthquake, the most destructive type of seismic wave that caused a rolling motion is known as a Surface wave. Thus, the correct option for this question is C.

pleaseee helppppp
Answer: B. plant population would suffer because the soil would have fewer available nutrients.
Explanation:
Earthworms are called a farmer's best friend as they make the soil more fertile. When earthworms purify the soil it makes it easier for the plants to grow as the soil is mineral rich. Decrease in the population of earthworms would make it difficult for the plants to grow because of the less fertile soil.
