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.

Volcanoes czn change the earths surface, because over time, the lava from the volcanoes builds up, and creates and destroys land over time. We can look a for example Hawii, USA. This state is made up of small islands that were created by volcanoes, that are constantly changing the land.
I hope this helps!
