Mid ocean ridges which contribute to the process of sea-floor spreding form as a result of?
Mid-ocean ridges form as a result of tectonic plate divergence, where two oceanic plates move apart. This movement allows magma from the mantle to rise and solidify at the ocean floor, creating new oceanic crust. As the plates continue to separate, new material is added, leading to the process of sea-floor spreading. This process is crucial for the renewal of the Earth's crust and plays a significant role in plate tectonics.

Mid ocean ridges which contribute to the process of seafloor spreading form as a result of?
Mid-ocean ridges form as a result of tectonic plate divergence, where two oceanic plates pull apart due to convection currents in the Earth's mantle. As the plates separate, magma rises from the mantle to fill the gap, creating new oceanic crust. This process not only leads to the formation of the ridge itself but also contributes to seafloor spreading, as new crust is continuously generated and older crust is pushed away from the ridge.
What is the pattern of seafloor age in the ocean basins?
The pattern of seafloor age in ocean basins generally shows that the youngest seafloor is located at mid-ocean ridges, where new oceanic crust is formed through volcanic activity. As you move away from these ridges, the age of the seafloor increases, with older crust found near the continental margins. This pattern is a result of the process of seafloor spreading, which continuously pushes older crust away from the ridges. Consequently, the age of the seafloor increases symmetrically on either side of the mid-ocean ridges.
What is seafloor spreading and what forms as a result of seafloor spreading?
Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges as tectonic plates diverge and magma rises to the surface. This results in the creation of new ocean floor, leading to the expansion of ocean basins. As seafloor spreading occurs, features such as mid-ocean ridges, rift valleys, and volcanic islands can also form as a consequence. Additionally, this process contributes to the cycle of plate tectonics, influencing geological activity and the distribution of continents.
How does magma help seafloor spreading?
Magma plays a crucial role in seafloor spreading as it rises from the mantle at mid-ocean ridges, where tectonic plates are diverging. When magma reaches the ocean floor, it cools and solidifies, forming new oceanic crust. This process not only creates new seafloor but also pushes older crust away from the ridge, facilitating the movement of tectonic plates. As a result, seafloor spreading continuously reshapes the ocean floor and contributes to geological activity.
What phenomenon occurs as a result of seafloor spreading?
In 1960, seafloor spreading was hypothesized by Harry Hess of Princeton University. Seafloor spreading occurs at divergent boundaries and it is said to be the mechanism that operates along the oceanic ridge system to generate new seafloor. Thus, the result of seafloor spreading is the creation of new sea floor through the uplift of magma: magma raises from asthenosphere, new oceanic lithosphere moves from ridge, and it thickens, cools (becomes denser), and subsides.
How many centimeters does the seafloor move a year?
The movement of the seafloor can vary depending on the location, but on average it moves at a rate of a few centimeters per year. This movement is a result of plate tectonics and the process of seafloor spreading.

When solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
Yes, during seafloor spreading, when solid mantle rock rises due to plate tectonic forces, it experiences reduced pressure which leads to decompression melting. This process produces magma that eventually erupts onto the seafloor, creating new oceanic crust.
What happens to sediment when water slows down?
When water slows down, it loses its ability to transport sediment. As a result, the sediment will settle out of the water and accumulate on the riverbed or seafloor. This process is known as sedimentation.

Magma plays a crucial role in seafloor spreading as it rises from the mantle at mid-ocean ridges, where tectonic plates are diverging. When magma reaches the ocean floor, it cools and solidifies, forming new oceanic crust.

What is the zones places where the seafloor is forced under continents to drift?
These zones are known as subduction zones where tectonic plates collide, forcing one plate to be pushed beneath the other. This process leads to the formation of deep ocean trenches and can result in earthquakes, volcanic activity, and the creation of mountain ranges.
Why is the seafloor young?
The seafloor is continuously being created at mid-ocean ridges through seafloor spreading, where tectonic plates move apart and magma rises from the mantle to create new oceanic crust. As a result, the oldest seafloor is only about 200 million years old, much younger than continental crust which can be billions of years old.
What are sparks and how do they contribute to the process of combustion?
Sparks are small, hot particles that result from friction or ignition. They contribute to the process of combustion by providing the initial heat needed to ignite a fuel source, such as gas or wood. This ignition starts a chain reaction that releases energy in the form of heat and light, sustaining the combustion process.
