.At spreading boundaries, plates move away from each
other and gaps form between the plates. Convection
currents cause magma to rise from the mantle through
these gaps. Huge valleys can form. This type of plate
movement is responsible for seafloor spreading. The
Mid-Atlantic Ridge formed at plate boundaries that
were moving apart.At fracture boundaries, plates slide past each other.
This break in Earth's crust is called a fault. The
movement of the plates past each other can cause
strong earthquakes.The area where two plates push against each other is
called a colliding boundary. When plates collide, one
plate might slide beneath the other. When plates carry
continents into each other, towering mountains form.
Other times, deep ocean trenches, earthquakes, and
volcanoes can result.

What kind of plate boundary separates the arctic plate and the Pacific Plate?
Divergent Plate Boundary. (Seafloor Spreading).
What occurs at plate boundaries that are associated with seafloor spreading?
When seafloor spreading happens, a rift forms at the bottom of a ocean and separates to form new rock. This is an example of a divergent plate boundary
At a divergent boundary land is gained or lost?
At a divergent boundary, land is gained. Ocean ridges are prominent at divergent plate boundaries. Ocean ridges are areas of seafloor spreading. Seafloor spreading occurs as upwelling magma rises to the surface. This upwelling magma hardens and forms new seafloor.
What is the other name for a spreading plate boundary?
Divergent boundaries is the other name for a spreading plate boundary.
Are the North American Plate and the Eurasian Plate moving apart at a very slow rate?
Yes. The seafloor is spreading out from the Mid-Atlantic Ridge. The North American Plate is moving slowly SW from the boundary.
Where does seafloor spreading happen?
along plate boundaries
What is the mystery phrase of plate tectonics?
seafloor spreading
At which type of plate boundary is the youngest seafloor located?
At the mid-ocean ridges, a divergent plate boundary.
Does the theory of plate tectonics contain both seafloor spreading and continental drift?
Yes. The theory of plate tectonics is very broad, and it covers seafloor spreading, continental drift, plate boundaries and so on.
What is the mystery phrase on the plate tectonics worksheet?
seafloor spreading
Which type of boundaries is seafloor created by?
Seafloor is created at divergent plate boundaries called the mid-ocean ridges.
What is the fastest spreading divergent plate boundary?
The mid-ocean ridge system is the longest continuous divergent plate boundary on Earth.
