Which geologic process forms new crust on the ocean floor?
Seafloor spreading is the geologic process that forms new crust on the ocean floor. This occurs at mid-ocean ridges, where tectonic plates move apart and magma rises to the surface, solidifying to form new oceanic crust.
What is a spreading center on the ocean floor?
sea floor-spreading..;)
Why did arthur Holmes think the sea floor was spreading?

What tools were used to prove seafloor spreading?
Tools such as sonar mapping, geologic sampling, and paleomagnetism studies were used to provide evidence for seafloor spreading. Sonar mapping allowed for the creation of detailed maps of the ocean floor, revealing features such as mid-ocean ridges and deep-sea trenches. Geologic sampling involved collecting rock samples from the ocean floor to study their age and composition. Paleomagnetism studies focused on analyzing the alignment of magnetic minerals in rocks, providing evidence of past changes in Earth's magnetic field that support the idea of seafloor spreading.
Where sea floor spreading occurs?
Sea floor spreading occurs at the mid ocean ridges.
Mid-ocean ridges which contribute to the process of sea-floor spreading as a result of?
Mid-ocean ridges contribute to sea-floor spreading through tectonic activity where tectonic plates diverge. As these plates pull apart, magma from the mantle rises to fill the gap, creating new oceanic crust. This process continuously pushes older crust away from the ridge, resulting in the gradual expansion of the ocean floor. Additionally, the formation of new crust at mid-ocean ridges is accompanied by volcanic activity, further contributing to the dynamics of sea-floor spreading.
How do you use sea-floor spreading in a sentence?
The Super Continent was broken apart, in part by sea-floor spreading.Scientists discovered that sea-floor spreading continues to move the continents.Sea-floor spreading can be measured using specialized equipment.
What is the primary site for sea floor spreading?
Sea floor spreading occurs at mid-ocean ridges
Is floor spreading an earthquake?
No.
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.
Which process causes the earth's crust to be continuously formes by volcanic activity?
Seafloor spreading
