Answer:
Surface waves have a longer duration and higher amplitude than body waves.
Explanation:
The stark difference between an earthquake body and surface waves is such that they have longer duration and a higher amplitude compared to body waves.
There are two categories of seismic waves that usually accompanies an earthquake:
- body waves are faster and perpetuate in the subsurface. They reach the seismic station first and are discovered faster.
- surface waves arrives later and they cause the damage produced by most earthquake waves. They perpetuate on the surface.
- surface waves are the love and Rayleigh waves
- body waves are the primary and secondary waves.
The correct option is a. natural lake that is dry for long periods of time.
<h3>What is playa?</h3>
Playas are flat-bottomed depressions that are sometimes surrounded by water which it slowly seeps into the groundwater system or vaporizes into the atmosphere. As a result, salt, sand, and mud are deposited along the depression's bottom and around its edges.
Some key feature of playa are-
- Playas are also known as pans, flats, or dry lakes.
- They are typically found in inner desert watersheds and close to coasts in arid and semi-arid regions.
- The flattest recorded landforms are playas. Typically, their gradients are less than 0.2 meters per kilometer.
- Many kilometers of surface may be submerged when only a few centimeters of water are added.
- The nearly flawless flatness that is so distinctive of these dry region landforms is developed and maintained by the process of flooding.
- The middle, level basins of arid plains are called playas. They need drainage from the inside to a place where evaporation far outweighs intake.
- A playa lake arises when the area is inundated, concentrating salts and fine-grained debris.
- Playa terminology is somewhat confusing due to the abundance of regional names.
