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.
Why is the mid-ocean ridge the longest mountain range?
The mid-ocean ridge is the longest mountain range because it stretches for over 65,000 kilometers around the world's ocean basins. It is formed by the movement of tectonic plates spreading apart, creating new oceanic crust and pushing the older crust away from the ridge. The continuous process of seafloor spreading along the mid-ocean ridge contributes to its significant length.
How is seafloor spreading different than continental drift?
Seafloor spreading is the process where new oceanic crust is formed at mid-ocean ridges and then moves apart, while continental drift refers to the movement of continents on the Earth's surface. Seafloor spreading is one mechanism that helps drive the movement of continents as part of plate tectonics.
How is magnetism used to support the theory about seafloor spreading?
Magnetism is used to support the theory of seafloor spreading through the study of magnetic stripes on the seafloor. These stripes are aligned with the Earth's magnetic field and provide evidence for the process of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, the magnetic minerals in the rocks align with the Earth's magnetic field, creating a record of magnetic reversals over time that support the theory of seafloor spreading.
How does the age of rocks in the seafloor provide evidence of seafloor spreading?
The age of rocks gets progressively younger as you move away from the mid-ocean ridges, where seafloor spreading occurs. This supports the theory of seafloor spreading, as new crust is being formed at the ridges and then moves away from them over time. This process leaves a record of older rocks further from the ridges and younger rocks closer to them.
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.

Description of seafloor spreading?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
Does seafloor spreading hold the plates in place?
No, seafloor spreading does not hold the plates in place. Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed and spreads apart. It is driven by the movement of tectonic plates, which are actually responsible for holding the seafloor in place.

The mid-ocean ridge is the longest mountain range because it stretches for over 65,000 kilometers around the world's ocean basins.

What is it called when two ocean plates move apart and new crust is formed?
Seafloor spreading
A place where seafloor spreading occurs.?
2. Mid Ocean Ridges are the place where new crust is formed. 1. oceanic plates or oceanic crust
Ocean crust is formed were in the ocean?
Ocean crust is formed at seafloor spreading centers. One example of this is the Mid-Atlantic ridge.
Why are the magnetic strips in the pacific ocean wider than the ones in the Atlantic ocean?
The Pacific seafloor formed at a faster spreading rate than the Atlantic seafloor.
What is ocean-floor spreading?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
What earth features do the three slits represent in seafloor spreading model?
The three slits in the seafloor spreading model typically represent mid-ocean ridges where new oceanic crust is formed. These slits show where magma rises up from the mantle, solidifies, and creates new crust as the tectonic plates move apart. This process allows for the continuous expansion of the oceanic crust.
How is seafloor spreading different than continental drift?
Seafloor spreading is the process where new oceanic crust is formed at mid-ocean ridges and then moves apart, while continental drift refers to the movement of continents on the Earth's surface. Seafloor spreading is one mechanism that helps drive the movement of continents as part of plate tectonics.
