WorksheetsG8 Geography - U2WK3 - Tectonic Plates & Earthquakes
Total questions: 15
Worksheet time: 8mins
What is the lithosphere?
The liquid layer of the outer core
The entire Earth's mantle
A tectonic plate made of the crust and upper part of the mantle
The theory of how continents move
The theory that suggests continents were once joined in a single landmass and have since drifted apart is called:
Mantle Convection Theory
Continental Drift
Plate Tectonics
The Lithosphere Theory
What is the primary cause of tectonic plate movement?
The rotation of the Earth
The gravitational pull of the moon
Convection currents in the mantle
The magnetic field of the outer core
I am a boundary where two tectonic plates move away from each other. What am I?
Convergent Boundary
Divergent Boundary
Transform Boundary
Subduction Boundary
I am a boundary where two tectonic plates slide past each other horizontally. What am I?
Convergent Boundary
Divergent Boundary
Transform Boundary
Sliding Boundary
What is an earthquake?
The opening in the Earth's crust where lava erupts
The sudden shaking of the Earth's crust
A giant ocean wave caused by underwater landslides
The process of one plate sinking beneath another
Where do most earthquakes occur?
In the middle of tectonic plates
At fault lines where tectonic plates meet
Only on the ocean floor
Randomly across the Earth's surface
What causes earthquakes to happen?
Heavy rainfall loosening the ground
Pressure building up as plates get stuck then suddenly releasing
The Moon's gravitational pull on the Earth
Volcanic eruptions shaking the ground
What are seismic waves?
Waves in the ocean caused by earthquakes
The energy that travels out from an earthquake's focus point
The sound waves made by crashing tectonic plates
Radio waves used to detect earthquakes
What does the magnitude of an earthquake measure?
How long the earthquake lasts
The depth of the earthquake below the surface
The amount of energy released by the earthquake
How many people felt the earthquake
If one earthquake has a magnitude of 6.0 and another has a magnitude of 5.0, how much stronger is the first earthquake?
2 times stronger
5 times stronger
10 times stronger
100 times stronger
Why are shallow earthquakes (0-70km deep) usually more destructive?
They last longer than deep earthquakes
The shaking is stronger at the Earth's surface
They always have higher magnitudes
They only happen in populated areas
What instrument is used to record earthquakes?
Thermometer
Seismograph
Barometer
Anemometer
Which of these is a PRIMARY impact of an earthquake (happens immediately)?
Diseases spreading due to poor sanitation
People becoming homeless
Buildings collapsing
Economic problems lasting for years
Which of these is a SECONDARY impact of an earthquake (happens later)?
Ground shaking
Roads cracking
Negative economic impact
Bridges falling down
