A hot spot is an area in the mantle of the earth where heat increases during the convection phase. This heat makes it easier for rock to melt. The melted lava, known as magma, drives volcanoes into cracks in the crust. There was a mistake. It does happen instead in abnormally hot centers called mantle feathers.

A. Earth's magnetic field reverses over time; the changes show that seafloor spreading has taken place over time.
Explanation:
The pattern of the magnetic minerals in seafloor ridges are aligned in a repeating pattern because the earth's magnetic field reverses overtime.
This provides evidence because the changes shows that the sea floor spreading has taken place over time.
- The concept of sea floor spreading was first suggested by Harry Hess in the early 1960's.
- Using sophisticated tools, he was able to discover stripe patterns of magnetic minerals in rocks.
- The earth can be likened to a giant bar magnet
- The geomagnetic field originates from the core where the movement of molten metals induces magnetism.
- In a fresh cooling magma, the metallic minerals are able to align their domains with the prevailing magnetic field.
- At some point the magnetic field is normal with a very strong intensity. At other times the intensity is low and it reverses.
- The minerals keeps track of the changes.
- This leads to striped pattern that has been used to suggest sea floor spreading.

Answer:
E. Malaria
Explanation:
Schizogony refers to the process of asexual reproduction through the process of multiple fission. The malaria parasite, <em>Plasmodium</em> species, enters the human body through the bite of female anopheles mosquitoes.
These mosquitoes carry haploid sporozoites in their saliva which are released into the bloodstream of human. The haploid sporozoites enter the liver cells where they multiply and increase their number through the process of multiple fission.
The process of schizogony in sporozoites of malaria parasite produces merozoites which are then released from the liver cells.
