What happens along a divergent boundary between two oceanic plates?
A rift valley, volcano, earthquake, trench.
Where is active seafloor spreading occurring today?
At any divergent plate margin: The Mid-Atlantic Ridge The boundary between the African Plate and Arabian Plate (the Red Sea) Great Rift Valley West Antarctic Rift East Pacific Rise Pacific-Antarctic Ridge Galapagos Rise Gakkel Ridge
Give two pieces of evidence for seafloor spreading?
Geographic similarities between continental margins on both sides of the Atlantic Ocean and similarity of strata and fossils found on those margins.
Describe how seafloor spreading occurs along the Juan de Fuca ridge?
scientist discovered that when axial erupted, boiling hot water shot up out of the volcano followed by a great amount of super hot lava much of this filled part of the gap between pacific plate and the juan de fuca plate creating a new seafloor
What is the boundary between the troposphere and stratosphere?
The boundary between the troposphere and the stratosphere is called the tropopause.
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
Place where seafloor spreading occurs?
Seafloor spreading occurs at the boundary between two tectonic plates. As the plates divide, magma comes up through the crack and cools to form new sea floor. The farther away the floor is from the boundary, the older it is.

What Is the mechanism responsible for producing the new seafloor between two diverging plates?
Sea Floor spreading
What is the mechanism responisble for producing the new oceanic crust between 2 diverging plates?
Seafloor Spreading.
At what type of boundary did the 1960 Chilean earthquake occur?
At a convergent boundary between oceanic and continental crust where subduction is occurring.
When India and Australia move in different directions what type of plate boundary will form between them?
A divergent boundry will form beetween them.
Explain the relationship between trenches and seafloor spreading?
1. New sea-floor is created by the upwelling of magma at mid-ocean spreading centers; old ocean floor is destroyed by subduction at deep sea trenches. 2. The area is a subduction zone. Magma from underground comes up and destroys that crust. That crust is then recycled and the magma cools and hardens. That creates new land, that creates the trenches. Seafloor spreading is in the ocean and happens with convection currents. That is the relationship between. 3. As new seafloor is formed at mid-ocean ridges, the old seafloor is pushed down into trenches at subduction zones.
What could wegener not satisfactorily explain about continental drift?
No
Boundary between two plates that are moving apart?
Convergent: plates move into one another.Divergent: plates move apart.Transform: plates move sideways in relation to each other.
What is the relationship between platetectonics and seafloor spreading?
Plate tectonics is the theory that earth is made of plates that move slowly. Sea floor spreading is related to this because the split created in the sea floor is created by the plates moving apart.
