Venus will help us understand what happens when the greenhouse effect is really extreme but it's not a really good example of what will happen to Earth because of human activities. Life on Earth would completely die due to the extreme temperatures way before reaching even half of the concentrations of carbon dioxide on Venus. Mars doesn’t really have any greenhouse effects. Mars does have some atmospheric carbon dioxide but almost no atmosphere but the atmosphere it does have is so thin that it cannot keep energy from the Sun. That’s why there are extreme temperature contrasts between day and night and sun or shade. However, most scientists say that Mars used to be warmer in and even had oceans, which means that the atmosphere was also very different. About 3600 million years ago, something happened and the planet evolved towards its current state. studying the planet could tell us what could have caused such a huge change
The name for such a hole is "caldera" which is a word of Spanish origin meaning "a pot" or a "cooking pot" (thing of cauldron!) - and this word is used because it resembles the shape of this hole.
Often the Calderas are filled with water forming lakes and often there is an island in the middle of the water.
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.

Our sun, is only a medium size star!
Answer:The difference between urban growth and urbanization is that urban growth reflects a general increase in either the land area or the population size of an urban area. Urbanization is about the relative proportion of people residing in urban areas in a given area (such as a region, country or continent).
