What else can I help you with?
How does the ocean floor keep getting wider but the earth stays the same size?
Because the Earth's tectonic plates are constantly moving
Does two plates moving apart cause sea floor spreading?
Yes, two tectonic plates moving apart can cause sea floor spreading. As the plates separate, magma rises up to fill the gap, solidifying to form new oceanic crust. This process contributes to the expansion of the ocean basins.
A mid-ocean ridge forms along what plates?
A mid-ocean ridge forms along divergent plate boundaries, where tectonic plates are moving apart. These boundaries occur where magma rises to the surface, creating new oceanic crust and extending the ocean floor.
How sea floor spreading provide evidence for tectonic plates?
by the plate tectonic and the ocean bridges
What are Mendocino Molokai and Galapagos are names of fracture zones in the floor?
Mendocino, Molokai, and Galapagos are names of fracture zones in the ocean floor, where tectonic plates are moving away from each other. These fracture zones are characterized by a series of faults and ridges that form due to the movement of the Earth's tectonic plates. They play a significant role in shaping the geology and topography of the ocean floor.
Why is it unlikely that some of the tectonic plates will stop moving?
The lithosphere and sea floor spreading are both factors in the movement of tectonic plate movement. As there is no foreseeable reason for the currents to stop, there is also no foreseeable reason for all tectonic plate movement to stop.
What moves the ocean floor?
the tectonic plates under the earths surface
Does new land get made when the plates are moving towards each other or apart?
New Land Is Created By Magma Or Lava Spilling Out Onto The Sea Floor, But This Is Counteracted By The Movement Of Tectonic Plates , As This New Land Is Formed Some Old Land In The Form Of A Plate Is Forced Under Another Plate. So New Land Is Not Formed Via Plates :)
Sea-floor spreading occurs in places where two plates are doing what?
Sea-floor spreading occurs in places where two tectonic plates are moving away from each other. Magma rises to the surface, creating new crust as the plates separate. This process is a key mechanism driving the movement of Earth's lithosphere.
What provides the most evidence for the theory of plates tectonic?
The spreading of the sea floor.
Where does sea floor spreading occur?
Sea floor spreading occurs along mid-ocean ridges, underwater mountain ranges where two tectonic plates are moving apart. Magma rises from the mantle to create new oceanic crust as the plates diverge, pushing the older crust away from the ridge. This process helps drive the movement of tectonic plates and is a key component of the theory of plate tectonics.
How does the movement of tectonic plates and continents relate?
When the plates drift apart through sea floor spreading, so do the continents
