What is a tectonic plate?
A cloud formation
A rigid section of Earth’s lithosphere that moves over the mantle
A liquid part of the outer core
A type of rock formed in water
What is subduction?
When two plates move apart
When magma rises to form a volcano
When one plate sinks beneath another
When plates slide past each other
What is a plate boundary?
The edge of a continent
The area where two tectonic plates meet
A fault in the middle of a plate
A break in the atmosphere
What is the mantle?
The outermost layer of the Earth
The core of the Earth
The layer beneath the crust where convection occurs
A type of volcano
What is a convection current?
The movement of water in the ocean
The circular movement of molten rock in the mantle that causes plate movement
Wind patterns in the atmosphere
The motion of tectonic plates sliding past each other
At a transform boundary, two plates:
Move toward each other
Move away from each other
Slide past each other
Stay completely still
Which feature forms at a divergent boundary?
Ocean trench
Rift valley or mid-ocean ridge
Mountain range
Earthquake zone only
What usually occurs at convergent boundaries where subduction happens?
Rift valleys
Earthquakes and volcanoes
New crust formation
No geologic activity
Which evidence supports the theory of plate tectonics?
The color of ocean water
Similar fossils found on different continents
The location of forests
The rotation of the moon
Why do earthquakes often occur at plate boundaries?
The plates are smooth
Pressure builds as plates interact
The crust melts completely
Wind pushes the plates
What happens to the plate that subducts into the mantle?
It floats back to the surface
It disappears immediately
It melts and becomes part of the mantle
It forms a new island
What is most likely to happen to Earth's surface over millions of years due to plate motion?
It will stay the same
Continents will shift, and new landforms will form
Water will stop moving
All volcanoes will erupt at once
Where is new crust created?
Subduction zones
Transform boundaries
Mid-ocean ridges
Hot springs
What technology is used to measure plate motion directly?
Thermometers
GPS satellites
Telescopes
Seismographs only
Which of the following landforms is most likely to form at a convergent boundary between two continental plates?
Mid-ocean ridge
Volcanic island
Mountain range
Ocean basin
Explain the process of plate tectonics and its impact on Earth's surface.
