Primary succession occurs when there are no remains of the previous ecosystem.
Secondary succession occurs when there are still remains of the ecosystem, so secondary succession kind of has a head start.
Uses natural pressure
Has groundwater stuck between impermeable layers
are the statements which describe the attributes of an Artesian well.
<u>Explanation</u>:
- Artesian well, well from which water is pumped under natural pressure without pumping. It is dug or dug wherever a soft dip, porous rock layer obtains water along its ridge at a point higher than the rate of the ground surface at the well site
- .First, artesian groundwater is the same as any other groundwater type; the only distinction is how it reaches the surface.
- An artesian well is simply a well that doesn't involve a pump to get water to the surface it happens when there is sufficient pressure in the aquifer. This gives rise to positive pressure.
He collected evidence for his theory for 8 years.
<h3>What theory did Darwin put forward after his voyage in HMS beagle?</h3>
From 1831 to 1836, Charles Darwin traveled the world in the HMS Beagle as a naturalist. His findings and experiences aided him in formulating the theory of evolution by natural selection.
Darwin was fortunate to travel to the Galapagos Islands on the Beagle, where he saw a variety of creatures and birds that had developed in a solitary setting. His discoveries inspired him to develop his well-known natural selection theory. Darwin's hypothesis states that differences within species happen at random and that an organism's capacity to adapt to its environment determines whether it will survive or become extinct.
Important observations regarding the geology of the islands and coasts that Darwin visited are also noteworthy. He put forth a notion regarding how atolls are formed. Small islands made of coral reefs called atolls surround lagoons. Most of them may be found in the Pacific. Bikini Atoll, which is northwest of Hawaii, is one example.
