Evaporated water goes into the clouds, comes down as rain, and evaporates again
Answer:
The correct answer is - rainwater or groundwater form carbonic acid that dissolves sections of bedrock.
Explanation:
A sinkhole is a natural hole or cave-like structure formed on the surface of the due to the chemical weathering of sections of bedrock made of carbonate rocks like limestone, dolomite, as well as salt beds or rocks.
Rainwater or groundwater comes in contact with CO2, a weak acid known as carbonic acid is formed, That can dissolves or weathers the lime stone or the carbonate rock of sections of the bedrocks and makes huge cracks or hollow out vast networks of caves.
This is a scientific model because weather is testable and observable, we can see weather patterns using satellites, and well, its testable.
What is a fossil?
Fossils are fossilised (petrified) remains of animals/plants. A fossil though, is only a fossil, when it is from a different geological era.
How does that relate to evolution?
Evolution and fossils are very related. When we scan the DNA of different fossils, we find that the DNA can be similar to living species we have today, which helps us trace back their origins.
Tracing back a species origins is not something we do just to see how that species changed along time. When we manage to make an evolutionary chart of a species, we know how they changed, what they changed, and maybe not more, but very importantly, when the previous species were extinguished. If we know when they were extinguished, we can find out what caused that extinction:
- A lack of adaptation.
- Lack of resources.
- Temperature changes.
- Increase of predators.
- Deadly migrations.
- Other natural disasters.
So, in other words, by studying one species, we can study our own planet.
