Answer:
D. magnetic polarity reversals
Explanation:
The marine magnetic anomalies are the result of two things; the seafloor spreading at the mid-ocean ridges and the magnetic polarity reversals.
The mid-ocean ridges are the places where the new crust forms. This places also have big influence on the magnetic anomalies, with the reason being that the magnetism has higher influence in this parts.
Also, the magnetic polarity reversals play a big role. The Earth has not always had the same magnetic polarity, and multiple times throughout its past the North and South Poles have been switching places when it comes to the magnetism.
The igneous rocks on the ocean floor have proof in them about this, as the metallic components are reacting to the magnetism and face toward the stronger magnetic field.
The plate boundaries that forms the territory of the Atlantic Ocean is known as the Mid-Atlantic Ridge.
<h3>What is the Mid-Atlantic Ridge?</h3>
This refers to the underwater mountain system formed by plate tectonics as a result of a divergent plate boundary that runs across the coast of Antarctica.
Therefore, the plate boundaries that forms the territory of the Atlantic Ocean is known as the Mid-Atlantic Ridge.

Oak forests are what is found
Answer:
A) fizzes when acid is dropped on it
Explanation:
Calcite will react acid in a reaction called effervesce producing small Co2 bubbles similar to the ones when you open a can of soda
Answer: Before the polar ice caps melt, the ice will have no effect on the earth's moment of inertia because it's distance from the axis of rotation is close to zero.
When the ice melts, the moment of inertia will increase because the mass of ice is spreading out around the whole earth.
