Answer:
Duration of the magnetic polarity event
Rate at which the plates are moving away from the mid-ocean ridge
Explanation:
The marine magnetic anomaly usually refers to the variation that occurs in terms of the magnetic field strength of the earth. This takes place because of the presence of minerals within the rocks of seafloor that contains high magnetic property.
These magnetic anomalies occurring in the marine rocks cover only about 1% of the total strength of the geomagnetic field. It shows either positive or negative anomaly.
Some of the factors that influence the width of this marine magnetic anomalies on the rocks of ocean-floor includes:
- The amount of time it takes during the magnetic polarity event
- The rate at which the tectonic plates move at a divergent plate boundary from the mid-oceanic ridge.
Answer: A primary consumer that obtains its energy from the consumption of plants
.
Explanation: This is the only option that makes sense. A monarch is not a producer since it is not a plant. A monarch is not a decomposer of course. Why is it a primary consumer? because monarchs eat from a plant and then are eaten by a secondary consumer.
Suppose a sand-colored rat lives in the desert. Its cameoflague against the sand helps it survive, but if the desert were covered in ash, its numbers would decrease because it doesn't have cameoflague anymore and can be easily spotted by predators.
