_______ are the breaks in the Earth’s crust.
What are faults
_______ ________ occur when two plates slip past each other, moving in opposite directions resulting in frequent earthquakes, and tsunamis
What is Transform boundaries
Earth’s inner core is made up of __________ .
what is solid metal

___________ is the heat transfer by direct contact of particles of matter.
What is conduction
When two continental plates collide, they often form _________.
What are mountains
__________ _________ occur when two plates move apart, or diverge; usually occur at the mid-ocean ridge resulting in ridges, trenches, seafloor spreading, and valleys

What is Plate tectonics
In our experiment which jar had to go on top for the two colors not to mix, and why?
hot jar on top because it is less dense
__________ is the transfer of energy through empty space, having no direct contact between the heat source and object.
what is radiation
