Plate Tectonics
The rising and sinking of magma in the asthenosphere that causes tectonic plate movements is known as ________.
What are convection currents
This geologic feature is formed due to the collision of continental-continental plate interactions at convergent boundaries
What are mountains
The plate boundary in which earthquakes most often occur
What is a transform plate boundary
The plate boundary most associated with the formation of volcanoes that occurs when oceanic plates sink below continental plates
What are subduction zones at convergent boundaries
the idea that continents were once a giant landmass and have moved away from each other over time to their current locations
What is continental drift?
At this plate boundary tectonics plates pull away from each other.
What is divergent plate boundaries
This geological feature forms at subduction zones where oceanic crust is recycled as it is pushed under a continental plate
What is a trench?
Seismic waves that push and pull on plates due to compression forces
What are P-waves
The molten rock below Earth's surface
What is magma
The type of boundary in which the Marianas Trench can be found
What is a convergent plate boundary
At this type of plate boundary tectonic plates move towards each other.
What is a convergent plate boundary?
This geological feature can be found at divergent boundaries of oceanic plates where seafloor spreading also occurs
What is a mid-ocean ridge?
The type of seismic waves that moves slowly and moves plates up and down due to shear forces
What are S-waves
This component can determine the viscosity of lava
What is silica
the creation and movement of oceanic crust at mid-ocean ridges
What is seafloor spreading?
At this plate boundary tectonic plates move past each other, side by side.
What is a transform plate boundary?
This is the geological feature that forms at divergent boundaries of continental plates
What is a rift valley
The type of fault most associated with earthquake activity
What is a strike-slip fault
What is a shield volcano?
The fault type that occurs when tension pushes and pulls plates
What is a normal fault
This explains that the Earth's crust is made of different plates that glide over the asthenosphere
What is the Theory of Plate Tectonics
The location in which areas of the Earth's crust within a tectonic plate can be thin and allow volcanic islands to form
What are hot spots
the reason why buildings should be made of stronger, more flexible materials
What is to reduce earthquake damage?
The area of tectonic plate movement in which most of the world's volcanoes can be found
What is the Pacific Ring of Fire
What is density
