Divergent Boundaries
what is a divergent boundary?
where two plates move apart or diverge
what is a convergent boundary?
where two plates come together, causing a collision where one plate is subducted
what is a transform boundary?
where plates slide past one another moving in opposite directions
What do P and S waves help scientist know about inner earth?
P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth.
Rock that is formed by heat and pressure.
Metamorphic
what happens at divergent plate boundaries?
rock rises from the mantle then hardens which adds new solid rock to the edges of both plates
what is subduction?
when one plate slides under another
what happens to the crust at a transform boundary?
crust is neither created or destoryed
Why are earthquakes and volcanoes created in the ring of fire?
The Ring of Fire is a region around much of the rim of the Pacific Ocean where many volcanic eruptions and earthquakes occur due to plate movement.
When rock is spewed out of a volcano, hardens and cools.
Igneous
what happens to crust at the divergent plate boundary?
crust can be created
what happens when two continental plates collide?
They create mountains. The amazing Himalaya Mountains are the result of this type of convergent plate boundary.
what is a real life example of a transform boundary?
the san andreas fault
What type of wave is the most destructive? Why?
Surface waves
The move in all directions
Sediment
What fault is created at a divergent boundary and what is the stress?
Normal fault
Tension
What is created when a oceanic and continental plate collide?
Trench is formed on the oceanic side. Continental crust is created and oceanic crust is destroyed.
where can you find transform boundaries?
canada / alaska / new zealand / california
When plates slide past each other they create ______ fault with ________ stress
Strike slip
Shearing
Compacting and Cementing
What geological feature is created by a Divergent Plate Boundary?
Rift Valleys / mid - ocean ridge
what geological feature can be created by a Convergent plate boundary?
mountain chain / sea floor trench
what is one geological feature that is created by a transform boundary?
earthquakes
Hanging wall slides up at this boundary and creates ______ stress.
Convergent Boundary
Compression
Sediment can be melted in this process
Subduction
