according to hesss theory, what might happen if the magma under a mid - ocean ridge cools? the magnetic stripes might reverse direction. the deep - ocean trench might become deeper. the crust at the ridge might form more quickly. the plates on either side of the ridge might stop moving.

Answer

Brief Explanations:

Hess's theory involves sea - floor spreading. Magma at mid - ocean ridges rises and cools to form new crust, pushing the plates apart. When magma cools, it solidifies and stops providing the driving force for plate movement. Magnetic stripes are related to Earth's magnetic field reversals, not directly to magma cooling. Deep - ocean trenches are formed by subduction and not directly affected by magma cooling at mid - ocean ridges. Faster crust formation occurs with more magma activity, not cooling.

Answer:

The plates on either side of the ridge might stop moving.
