What kinds of ocean currents might cause seafloor spreading?
Oceanic currents themselves do not directly cause seafloor spreading. Seafloor spreading is primarily driven by tectonic forces, specifically the movement of tectonic plates away from each other at mid-ocean ridges. This movement leads to the upwelling of magma from the mantle, creating new oceanic crust at the spreading center. Ocean currents can affect the distribution of heat and nutrients in the ocean, but they do not play a direct role in the process of seafloor spreading.
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 a constructive force caused by the convection in the mantle?
A constructive force caused by convection in the mantle is seafloor spreading. As hot mantle material rises and spreads out at mid-ocean ridges, it creates new oceanic crust, which pushes the older crust aside. This process helps in the formation of new oceanic crust and contributes to the widening of the seafloor.
How does the process of seafloor spreading occur with two tectonic plates moving away from each other?
Seafloor spreading happens when two tectonic plates move apart. Magma rises up from the mantle through the gap, creating new oceanic crust. As the plates continue to move apart, the new crust pushes the older crust away, causing the seafloor to spread.
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.
Which force is responsible for seafloor spreading?
Gravity in the oceanic crust is responsible for seafloor spreading.
Where is the place where seafloor spreading occur?
Mid-oceanic ridges
What is this is the process of creating new oceanic crust?
Sea floor spreading
Is seafloor spreading a process that forms a new oceanic crusts?
Yes, it is.
Is new oceanic crust formed at mid-ocean ridges?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
How do you explain the process of the seafloor spreading?
The seafloor spreading definition is the geologic process that occurs at the boundary between 2 plates where molten material within the earth pushes its way up, causing the plates to move away from each other. At these divergent boundaries molten material cools and hardens, creating new oceanic crust or seafloor
A place where seafloor spreading occurs.?
2. Mid Ocean Ridges are the place where new crust is formed. 1. oceanic plates or oceanic crust
Is ocean crust formed at a mid ocean ridge?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
In earths crust What type of rock is found under the oceans?
Oceanic crust, new oceanic crust is produced by seafloor spreading.
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.
What do the letters rorpsfgnloadeeasi spell in geology?
The anagram is "seafloor spreading" (creation of new oceanic crust).
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.
