Answer:
Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves.
Explanation:
Sea-floor spreading occurs when the sea floor spreads apart along divergent boundaries and forms the mid-ocean ridge. Magma is pushed up through cracks in the crust along the mid-ocean ridge. As the magma is thrust up and hardens it forms new crust and the ocean floor on both sides of the mid-ocean ridge move outward.
The Tropical Grassland is the most common type of Ecosystem in Africa.
Answer: (D) In the short term, the wild cheetah population will be incapable of surviving a natural disaster in the African grasslands.
Explanation:
It is said that the previous estimates of the population of cheetahs needed for them to survive a natural disaster were understated and yet on top of that, the current population barely meets those understated numbers. Their numbers are therefore not enough to survive a natural disaster as it is.
To top that all of, the population cannot increase in the short term because African grasslands cannot support a larger population. This means that should a natural disaster strike Cheetahs in the short term, their numbers would be unable to take it and they would not survive.
