Question

The process of seafloor spreading predicts that: (Select all that apply.)

A. Seafloor moves like a conveyor belt from spreading centers toward subduction zones.
B. The oldest seafloor will be found at subduction zones.
C. There is high heat flow from Earth's interior into the crust at spreading centers.
D. Continents shift locations because they are embedded in moving plates.

Answer 1

Seafloor spreading predicts that the seafloor moves like a conveyor belt, with the oldest seafloor found at subduction zones. Additionally, there is high heat flow from Earth's interior into the crust at spreading centers.

Step-by-step explanation:

The process of seafloor spreading predicts that:

1. Seafloor moves like a conveyor belt from spreading centers toward subduction zones. New crust is added at the spreading centers, and as it moves away, it makes room for more crust to be formed. This movement is often compared to a conveyor belt.
2. The oldest seafloor will be found at subduction zones. The subduction process causes old oceanic crust to be forced beneath another plate, where it eventually melts and gets recycled into the mantle. As a result, the oldest seafloor can be found at subduction zones.
3. There is high heat flow from Earth's interior into the crust at spreading centers. Spreading centers are areas where new crust is formed, and this process involves the upwelling of molten rock from the mantle, which releases a significant amount of heat into the crust.
