Answer:
I believe its C
Explanation:
C because when you'll have control over the variables (salt and water) You can measure how much salt or water is actually needed to determine the freezing temp.
Convection in the mantle and pressure of magma on the edge of the plate
Explanation:
Convection currents occur in the mantle because the upper mantle (asthenosphere) is generally cooler than the lower mantle. The convections apply upward pressure on the lower edges on the lithosphere as the melted rocks upwell from below. The lithosphere deflects the convections and as the convections churn clockwise of anticlockwise, they drag the lithosphere with it via friction. This is what is stipulated to cause tectonic plate movements.

The best answer to go with is b
The ocean crust is known to show a sequence of magnetic polarity given that it shows us that there is the formation of a new sea floor at the mid ranges of the ocean. This is where they are seen to separate from themselves on the sides of the ridge.
<h3>What is seafloor spreading?</h3>
This is the term that is used to refer to the spreading that occurs at the mid ocean ridges. These are the areas where the new oceanic crusts get to be formed.
Hence we can say that The ocean crust is known to show a sequence of magnetic polarity given that it shows us that there is the formation of a new sea floor at the mid ranges of the ocean. This is where they are seen to separate from themselves on the sides of the ridge.
