1. What is the difference between the lithosphere and the asthenosphere that makes up the mantle?
The lithosphere is made of a mixture of gasses while the asthenoshpere is made of solid material
The lithosphere is made of solid rock that forms the crust while the asthenosphere is more flexible hot rock that moves slowly just under the crust.
What plate boundary do you see
Transform
Convergent
At deep ocean trenches, seafloor is pushed back down into the earth where it will be “recycled” again someday as new earth. This process is called:
Subduction
Convection
What type of boundary do you see?
Transform
Divergent
_____________________________ currents within the mantle cause the earth’s plates to move and shift as molten material rises and falls due to density and gravity.
Conduction
Convection
Earth’s magnetic field is caused by movement of metals within the outer core of the planet and causes a compass to always point north.
True
False
The rising and falling of the rock and magma on the inside of the earth can cause ________________________ on the surface of the earth.
Volcanoes & Earthquakes
Mountain Formations
Faults to Form
All the above
What type of land formations do divergent boundaries make?
Oceanic ridges
Mountains
Volcano arc
Sea floor spreading
What plate boundary do you see?
Convergent
Divergent
When to continental boundaries converge they form _____________________________ on land.
Trenches
Mountains
What famous transform boundary is located in California?
San Andreas Fault
The Rock Fault
When pressure builds within the earth, it can suddenly break causing a ________________________________ to form.
break
fault
volcano
What layer is plastic-like and allows the crust to flow over it?
