Tectonic plates move because of this.
Mantle convection currents (and slab pull force)
The movement of plates at a divergent boundary
They move away from each other
A land feature that is produced at a convergent boundary is
A volcanic mountain range, an arc of volcanic islands...

Transform
What is Pangea?
A single gigantic continent that existed 250 million years ago.
What are the tectonic plates composed of?
Continental and/or oceanic crust plus a small part of the upper mantle.
What happens in the boundaries where mid-ocean ridges form?
Mid-ocean ridges form on boundaries where plates are spreading apart.
Transform faults, such as the San Andreas Fault system in California, occur where?
Transform faults occur on boundaries where plates are sliding past each other.
What process is building the Himalayas, the tallest mountains on Earth?
Two continental plates colliding is the process that built the Himalayas.
Type of boundary where lithosphere is constantly being made up.
The oceanic crust is constantly being created where plates are separating at divergent boundaries.
Name in order the inner layers of the Earth (4 or more).
Crust, Mantle (or Upper mantle, Lower mantle), Outer core, Inner core.
Plates do not move smoothly. The rocks on either side become jammed together and incredibly large forces build up as the plates either side continue to move. When the plates finally become 'unstuck', which natural hazards occur?
Earthquakes are formed when rocks move in this way (not volcanoes).
What part of the Earth is broken into 'plates'?
The lithosphere.
At which type of plate boundary do you get only earthquakes?
Transform boundary (Plates slide sideways past each other so there is no melting of rocks or gaps through which molten magma can squeeze up from below).
At which type of plate boundary is one plate pushed down into the mantle?
Convergent or destructive boundary (The plate that is pushed down into the mantle is the one that is destroyed)
What will you find in places where an oceanic plate subducts under a continental one?
A coastal (volcanic) mountain range
