Answer:</h2>
New crust forms <u>D. at ocean ridges</u>
.
<h2>
Explanation:</h2>
At mid-ocean ridges, there is separating of plate tectonics allowing the formation of new crust from the cool solid magma. The process leads to the formation of the new seafloor and it is called the new seafloor spreading.
Since the earth is not expanding to make way for spreading seafloor, at the subduction zone, the tectonics sink back into lithosphere or earth's interior. The new crust formation at ocean ridges can be a slow or fast process. Some ridges spread at 2 inches (5 centimeters) per year while others spread at 6 inches (15 Centimeter) per year.
