What is your understanding on the Seafloor spreading?
All continents are drifting.
Ages of rocks near a ridge are older than the ones far from it
Fossils of plants and animals are found in almost all continents.
Hot and less dense material from below the Earth's crust rises towards the surface at the mid-oceanic ridge
Which of the following BEST describe the seafloor spreading process?
Hot, less dense material rises towards the mid-ocean ridge. It then flows out of the fractured rocks, cools down and becomes the new seafloor. This new seafloor pushes the old seafloor away from the ridge and eventually undergoes
subduction.
Hot magma fueled by mantle convection bubbles up to fill these fractures and spills onto the crust. This bubbled-up magma is cooled by frigid seawater to form igneous rock.
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move towards each other, heat from the mantle’s convection currents makes the crust more plastic and denser.
Magma comes out of the ridge, cools to rock, and hardens. Old rock is pushed away as a new rock is formed at the ridge.
The old seafloor farthest from the ridge is destroyed in the subduction zone.
What can you say about the rate of movement of materials coming out from the mid-oceanic ridge and the materials sinking in
the subduction zone?
The rising of the materials from the ridge is slower than in the subduction zone.
The movement of the materials in both ridge and subduction zone is the same.
The rising of the materials from the ridge is faster than in the subduction zone.
There is no much movement of materials happening in both the ridge and subduction zone

The Earth's magnetic field is fluctuating.
