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?
Hot magma forced upward at mid-ocean ridges produces new oceanic crust as it solidifies upon contact with seawater. This process is known as seafloor spreading and helps to create new oceanic crust, causing the plates to move apart and leading to the formation of mid-ocean ridges.
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.
Is it true that as the new seafloor moves away from the ridge and becomes hotter it moves upward and forms still higher ridges?
Yes, it is true. As the new seafloor forms at mid-ocean ridges and moves away, it cools and becomes denser. The denser seafloor sinks lower, creating space for more magma to rise at the ridge, forming still higher ridges.
What is a Lacolith?
A lacolith is a type of igneous intrusion where magma pushes up the overlying rock layers without actually breaking through the surface. This creates a dome-like structure with a flat base and a rounded top. Lacoliths are typically found in mountainous regions and are associated with the formation of volcanic or plutonic rocks.
How did harry hess hypothesis explain seafloor movement?
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 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

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.
Which geological feature forms over time when Earth's crust cracks and the piece moves upward?
This is one way that mountains form.
Were does magma often move upward though in the crust?
Magma often moves upward through the Earth's crust along cracks and fractures in the rock, known as magma conduits. These conduits can be created by tectonic activity, such as the movement of tectonic plates, which can provide pathways for magma to reach the surface and form volcanic eruptions.
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.
Is the tornado alley in North America?
It reaches from southern America like around Texas and Oklahoma then it spreads upward toward the middle like kansas then northern upper states.

Is it true that as the new seafloor moves away from the ridge and becomes hotter it moves upward and forms still higher ridges?
Yes, it is true. As the new seafloor forms at mid-ocean ridges and moves away, it cools and becomes denser. The denser seafloor sinks lower, creating space for more magma to rise at the ridge, forming still higher ridges.
