Transform boundaries...
can cause an earthquake when they slide past each other.
move away from each other.
Never move.
cause mountains due to the plates colliding/moving towards each other.

prefix that means away
A plate boundary where two plates move away from each other
A plate boundary where two plates move away from each other
prefix that means away
13

17
What is a volcanic neck?
The largest type of intrusive igneous rock mass
It is formed when magma hardens in cracks, parallel to rocks
It is formed when magma hardens in cracks across rock layers
It is formed when magma hardens in a volcano’s pipe
18
How is a Composite volcano formed?
When lava cant flow because it is so viscous and builds up around the vent
From Cinders and ash that typically come from one eruption.
Low viscosity lava flows that build up over time
Alternating layers of lava and ash are erupted and form over many years.

edge of a tectonic plate
boundary of a tectonic plate
in only one place on earth
24
What is a convergent plate boundary?
Two plates collide into each other
It means the plates stay still
It destroyes volcanoes
It makes oceans
