What is an underwater mountain chain formed where new crust is created by seafloor spreading called?
The process of sea-floor spreading created the lithosphere under the Atlantic Ocean. As North America and South America moved away from Europe and Africa, the resulting crack was filled by mantle material, which cooled and formed new lithosphere. The process continues today. Molten mantle materials continually rise to fill the cracks formed as the plates move slowly apart from each other. This process creates an underwater mountain chain, known as a mid-ocean ridge, along the zone of newly forming lithosphere.
What else can I help you with?
True or False Mid-ocean ridges are actually underwater mountain ranges?
It is true that mid-ocean ridges are underwater mountain ranges. These ridges are long, seismically active submarine ridges associated with seafloor spreading.
What physical feature is created when the seafloor spreads?
A mid-ocean ridge is formed along a line created by sea floor spreading. It usually consists of parallel mountain ranges separated by a valley. Sea floor spreading is the result of plate tectonics, where two crustal plates are moving apart. The ridge is formed along lines of the weakest points between the two plates.
How do the ages of the rocks on the seafloor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
What formation is created in the rift of a spreading sea floor?
A mid-ocean ridge is created in the rift of a spreading sea floor. It is a continuous underwater mountain range formed by the separation of tectonic plates. Magma rises to the surface, creating new crust which pushes the existing plates apart.
What process forms the mid Atlantic ridge?
The Mid-Atlantic Ridge is formed by seafloor spreading, where new oceanic crust is created as tectonic plates move apart. Magma rises from the mantle to fill the gap, creating new crust at the divergent plate boundary. Over time, this process forms a continuous underwater mountain range along the center of the Atlantic Ocean.

It is true that mid-ocean ridges are underwater mountain ranges. These ridges are long, seismically active submarine ridges associated with seafloor spreading.
What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading

The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
Process that forms new seafloor?
The process that forms new seafloor is called seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is created through volcanic activity. As magma rises and solidifies, it adds to the seafloor, pushing older crust away from the ridge and creating a continuous process of crust formation.

How does seafoor age and magnetic clues support seafloor spreading?
Seafloor is youngest near the mid-ocean ridges and gets progressively older as you move away from the ridge. Magnetic stripes on the seafloor provide evidence of seafloor spreading, as they show alternating patterns of normal and reversed magnetic polarity that match the Earth's magnetic reversals over time. This supports the theory of seafloor spreading as new oceanic crust is created at the mid-ocean ridge and spreads outward.
Does seafloor spreading cause the earth's crust to expand?
Yes, seafloor spreading is a process where new oceanic crust is formed at mid-ocean ridges, causing the Earth's crust to expand. This occurs as magma rises to the surface, solidifies, and pushes older crust away from the ridge, creating new seafloor.
What is the difference of seafloor spreading and continental drift?
In continental drift it says that they were drifted apart by the spin of the earth and in seafloor spreading the earths crust is drifted apart by the ridges in the mid-ocean.
An underwater mountain chain that formed by sea-floor spreading is called a?
Underwater mountain chains that form where two tectonic plates are pulling apart are called mid ocean ridges. The largest is the Mid Atlantic Ridge.
What is called a sea wave that is created when the seafloor slips after an underwater earthquake?
Its called a Tsunami, Japan just had one and was devastated!
