What is the primary theory that explains plate motion?
The theory of plate tectonics.
True or False: The Earth’s lithosphere is divided into tectonic plates.
True.
Fill in the blank: The movement of tectonic plates is driven by ______ forces.
mantle.
What are the three main types of plate boundaries?
Divergent, convergent, and transform boundaries.
Multiple Choice: Which boundary is characterized by plates moving apart?
Divergent boundary.
What geological feature is typically formed at convergent boundaries?
Mountain ranges or deep ocean trenches.
True or False: Transform boundaries are known for creating new crust.
False.
Fill in the blank: The _______ is the layer of the Earth where tectonic plates float.
asthenosphere.
What is the primary mechanism that drives plate tectonics?
Convection currents in the mantle.
Multiple Choice: Which of the following is NOT a type of plate boundary?
Static boundary.
What is subduction?
The process where one tectonic plate moves under another plate.
True or False: Earthquakes can occur at all types of plate boundaries.
True.
Fill in the blank: The _______ fault is an example of a transform boundary.
San Andreas.
What is the significance of the Mid-Atlantic Ridge?
It is a divergent boundary where new oceanic crust is formed.
Multiple Choice: Which plate is responsible for the formation of the Himalayas?
Indian Plate colliding with the Eurasian Plate.
What role do hotspots play in plate motion?
They create volcanic islands as tectonic plates move over them.
True or False: Plate tectonics is a relatively new theory in geology.
True.
Fill in the blank: _______ is the process through which tectonic plates move and interact.
Plate tectonics.
What is a rift valley?
A lowland formed by the divergence of tectonic plates.
Multiple Choice: Which of the following is an example of a convergent boundary?
The Andes Mountains.
What is the role of plate motion in the rock cycle?
It facilitates the recycling of rocks through subduction and uplift.
True or False: Most earthquakes occur along plate boundaries.
True.
Fill in the blank: The _______ plate is the largest tectonic plate.
Pacific.
What is the relationship between plate motion and volcanic activity?
Volcanic activity often occurs at plate boundaries where plates interact.
