The correct answer is - Magma generated from a hot spot burned through the overlying plate to create volcanoes.
The Hawaiian Islands are all formed as a result of volcanic activity of a hot spot. The hot spot is stationary, but the islands are in the shape of a chain, not all in the same place. Also, the rocks on the islands that do not have active volcanoes are older, than the ones that do have volcanic activity. This suggests that the Pacific plate is moving. According the direction in which the islands are arranged, the Pacific plate seems to move toward northwest. As it moves, it moves over the hot spot. Since the hot spot is stationary, as the Pacific plate moves, eventually the volcanic activity will stop on the island that has moved further away from the hot spot. The magma from the hot spot will penetrate through the crust that came to be over it. That will result in new volcanic island emerging from the sea over the hot spot. The process goes on for millions of years, and it can result in hundreds of islands of volcanic origin.
Answer: Anaerobic respiration or Fermentation
Explanation:
When we are engaged in intense physical activity such as running or riding a bike, the muscles need energy to function and they get this from aerobic respiration.
They will quickly run out of the oxygen required to sufficiently use aerobic respiration however and will turn to anaerobic respiration which can produce energy in the absence of oxygen.
As the body uses anaerobic respiration however, lactic acid is produced and builds up in the muscles. It is this lactic acid that leads to the muscles feeling sore.
Answer:
Heat absorption increases as the albedo decreases. B
Explanation:
Answer:
The European diseases affected the people of the Western Hemisphere greatly. Outbreaks of various diseases brought by the Europeans to the Americas such as smallpox, influenza, malaria, diphtheria, etc. It killed many of the Native Americans and disrupted their societies. Due to the diseases having been in Europe for a longer time, the people got more immune to them, however, this was the first time the Native Americans were exposed to it.
Due to them not being immune, the mortality rate for a Native American catching a disease was extremely high, much higher than they would have been if it was already introduced. The Native Americans also had very limited health care therefore were not able to be treated as well as the Europeans. Because of this, the diseases affected them for much longer periods of time.
