Who ever told you that the answer is yes, is steering you straight to hell! The answer is magma not saltwater!

Seafloor spreading occurs because?
Because as the sea-floor spreads apart, magma is forced upward and flows from the cracks. It becomes solid as it cools and forms new sea-floor. As new sea-floor moves away from the mid-ocean ridge, it cools, contracts, and becomes denser.
What does hot magma forced upward at mid-ocean ridges produce?
Seafloor spreading
How did Harry Hess discover seafloor spreading?
Harry hess' hypothesis was hot/less dense material rises up the Earth's crust toward the mid-ocean ridges. When the seafloor breaks apart, magma is forced upward and through the cracks. It cools, and becomes a new seafloor. When it moves away from the mid-ocean ridge, it becomes denser and sinks. This helps form ridges.
What is a Lacolith?
When magma flows between rock layers and spreads upward, it sometimes pushes the overlying rock layers into a dome. The base of the intrusion is parallel to the rock layer beneath it.
What is the difference between spreading and subduction?
spreading: rock rises upward then spreads outward.subduction: rock moves inward then subducts downward under lighter rock.

Were does magma often move upward though in the crust?
Through cracks.

What could cause a rash that begins at the belly button and spreads upward to the neck?
One possibility is a yeast infection.
What happens to a coral reef if the sea level rises or if the sea floor spreads?
It continues to grow upward

Which geological feature forms over time when Earth's crust cracks and the piece moves upward?
This is one way that mountains form.
What is the theory that occurs when magma is pushed upward and flows through the openings in the ocean floor?
this usually happens when the sea floor spreads open.
What are the first symptoms of GSB?
The initial sensation of weakness or paralysis in the toes spreads upward within days to a few weeks to the arms and the central part of the body.
What is the difference between spreading and subduction?
spreading: rock rises upward then spreads outward.subduction: rock moves inward then subducts downward under lighter rock.
