Tectonic Basic
100: The Earth's outer layer is divided into large, _______-like pieces called plates.
puzzle
100: Convergent boundaries are when plates move __________ each other.
toward
100: Convergent boundaries can form these landforms.
mountain ranges
100: Fossil records show that all seven continents were once this.
Connected
100: The San Andreas Fault is found in this U.S. state and is known for frequent earthquakes.
California
200: Tectonic plates float on top of this hot, soft rock layer beneath Earth’s surface.
mantle
200: Divergent boundaries happen when plates move __________.
Apart
200: Subduction zones can lead to these natural disasters.
earthquakes and volcanoes
200: Similar rock formations on different continents show evidence of this.
plate movement or continental drift?
200: The Pacific Plate mostly lies under this large body of water.
he Pacific Ocean
300: Plates are made up of both continents and this other major feature.
ocean floors
300: Transform boundaries are when plates __________ past each other.
Slide
300: Divergent boundaries create these cracks in Earth's crust.
Rifts
300: Modern tools use this to track ongoing plate movement.
GPS
300: The “Ring of Fire” around the Pacific Ocean is known for having many of these.
volcanoes and earthquakes?
400: our planet is constantly doing this.
changing or moving
400: When plates push together, one may slide under the other. This is called __________.
Subduction
400: The Mid-Atlantic Ridge is an example of this type of boundary.
Divergent boundary
400: Plate tectonics drives this continuous process that recycles Earth's crust.
What is the name for this process?
The Rock Cycle
400: Movement along the San Andreas Fault mostly causes this type of boundary motion.
transform or sliding motion
500: The energy that moves tectonic plates comes from heat deep inside the Earth, also known as ____________ currents.
Convection Currents
500: At divergent boundaries, new rock material rises from Earth’s __________.
Mantle
500 : When oceanic crust meets continental crust at a convergent boundary, the denser plate does this.
sink or subduct beneath the other
500: Plates move about this many centimeters per year.
2-5cm
500: This plate is the fastest-moving plate on Earth and is responsible for many Pacific earthquakes.
