What are the three main types of plate boundaries?
Divergent, convergent, and transform boundaries.
True or False: Convergent boundaries occur when two tectonic plates move away from each other.
False.
Fill in the blank: At divergent boundaries, tectonic plates _____ each other.
move away from
Which type of boundary is characterized by plates sliding past one another?
Transform boundary.
What geological feature is commonly formed at convergent boundaries?
Mountain ranges or deep ocean trenches.
What are convergent boundaries?
Convergent boundaries are regions where two tectonic plates move towards each other.
What happens at convergent boundaries?
At convergent boundaries, one plate may be forced beneath another in a process called subduction.
What geological features are commonly formed at convergent boundaries?
Convergent boundaries can create mountain ranges, deep ocean trenches, and volcanic arcs.
What are the types of convergent boundaries?
There are three types of convergent boundaries: oceanic-continental, oceanic-oceanic, and continental-continental.
What are transform fault boundaries?
Transform fault boundaries are places where tectonic plates slide past each other.
What are the layers of the Earth?
The layers of the Earth include the crust, mantle, outer core, and inner core.
What is plate tectonics?
Plate tectonics is the theory that explains the movement of the Earth’s plates.
What geological events are associated with plate tectonics?
Volcanoes, earthquakes, and mountain ranges are associated with plate tectonics.
What is oceanic crust?
Oceanic crust is the part of the Earth’s crust that underlies the ocean.
What is seafloor spreading?
Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges.
What is the Continental Drift Theory?
The Continental Drift Theory suggests that continents have moved over geological time.
What is the Plate Tectonics Theory?
The Plate Tectonics Theory describes the large-scale movement of the Earth’s lithosphere.
What is a crustal plate?
A crustal plate is a rigid segment of the Earth’s lithosphere that moves over the asthenosphere.
Which layer of the Earth do miners dig into?
Miners dig into the Earth’s crust, which is the outermost layer.
