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.

No, the chemical equations for both processes are evidence that matter and energy or neither created nor destroyed
The result would be an increased atmospheric concentration, which alters the distribution or abundance of species. Leached phosphorus can then lead to algal blooms and that clogs the aquatic ecosystem.
Answer:
C
Explanation:
Consumers can't convert glucose, they don't take in carbon dioxide, and they can't produce Glucose, therefore it has to be C
