What else can I help you with?
Magnetic stripes on the seafloor are caused in part by?
symmetrical spreading of the ocean floor at mid-ocean ridges, where molten material rises to create new seafloor. As this material cools and solidifies, it records the Earth's magnetic field at the time, creating magnetic stripes on the seafloor. This phenomenon provides evidence for seafloor spreading and plate tectonics.
First related the symmetrical magnetic patterns in seafloor basalts to seafloor spreading at a mid-ocean ridge?
Lawrence W. Morley, Frederick John Vine, and Drummond Hoyle Matthews were the first to tie magnetic stripe anomalies to seafloor spreading. The magnetic anomalies was the first evidence that supported the theory of seafloor spreading.
What is seafloor spreading called?
Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges. This process occurs through the upwelling of magma from the mantle to create new crust as tectonic plates move apart.
What is the name of the continuous mountain range formed from seafloor spreading?
The mid-ocean ridge is the continuous mountain range formed from seafloor spreading. It is located underwater and stretches across the Earth's oceans, where tectonic plates are moving apart and magma rises to create new oceanic crust.
What is the modern seafloor spreading rate range?
Typical rates of spreading average around 5 centimeter (2 inches) per year.
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
How to Diagram the process of seafloor spreading?
A diagram that shows how seafloor spreading works.
Seafloor spreading begins when?
Seafloor spreading is triggered by a rift in a continental land mass.
Which force is responsible for seafloor spreading?
Gravity in the oceanic crust is responsible for seafloor spreading.
Which observation was not instrumenntal in formulating the hypothesis of seafloor spreading?
The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.
What does seafloor spreading have to do with the theory of continental drift?
Seafloor Spreading helped move the Continents to their current location.
What process forms new seafloor?
New seafloor is formed through a process called seafloor spreading, which occurs at mid-ocean ridges. Magma rises from the mantle and solidifies to create new crust as tectonic plates move apart. This continuous process results in the creation of new seafloor and plays a key role in plate tectonics.
What boundary creates seafloor spreading?
A divergent boundary creates seafloor spreading. At these boundaries, tectonic plates move apart, allowing magma to rise from below the Earth's surface and create new crust at the mid-ocean ridges.
What is the system of cracks that form where the seafloor is spreading apart called?
The system of cracks that form where the seafloor is spreading apart is called a mid-ocean ridge. These cracks are also known as rift zones and are where magma rises to create new oceanic crust.
Magnetic stripes on the seafloor are caused in part by?
symmetrical spreading of the ocean floor at mid-ocean ridges, where molten material rises to create new seafloor. As this material cools and solidifies, it records the Earth's magnetic field at the time, creating magnetic stripes on the seafloor.

What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
