put the steps of seafloor spreading in order from first to last. a crack forms. magma hardens. magma pushes upward. rock moves outward.
Answer
Answer:
- A crack forms.
- Magma pushes upward.
- Magma hardens.
- Rock moves outward.
Explanation:
Step1: Initial stage
First, a crack forms in the ocean - floor crust due to tectonic forces.
Step2: Magma movement
Then, magma from the mantle pushes upward through the crack.
Step3: Magma solidification
The magma cools and hardens as it reaches the ocean - floor environment.
Step4: Rock displacement
Finally, the newly formed rock moves outward away from the mid - ocean ridge as more magma continues to push up.
