Which list correctly shows the four major layers of the Earth?
Crust, magma, mantle, core
Lithosphere, mantle, outer core, inner core
Lithosphere, asthenosphere, mantle, core
Crust, mantle, iron core, magma core
Which layer of the Earth do scientists study most directly?
Inner core
Outer core
Mantle
Lithosphere
Why do scientists rely on indirect evidence to study the Earth’s core?
The core is too small
The core is underwater
The core is too hot and deep
The core changes shape
The lithosphere is commonly referred to as the Earth’s:
Core
Mantle
Crust
Asthenosphere
Which types of rocks make up the lithosphere?
Igneous, sedimentary, metamorphic
Basalt, granite, iron
Magma, lava, ash
Plastic rock, iron, nickel
What is the Mohorovicic discontinuity (Moho)?
The boundary between the inner and outer core
The boundary between the mantle and outer core
The boundary between the crust and mantle
A type of fault line
Why does mantle rock behave like a fluid?
It is completely liquid
It is made of iron
High pressure and temperature cause plasticity
It contains water
What type of motion occurs in the mantle that helps move tectonic plates?
Radiation
Conduction
Convection currents
Plate sliding
Which statement best describes the outer core?
Solid iron due to pressure
Liquid iron due to heat
Plastic rock
Solid rock
Why is the inner core solid even though it is extremely hot?
It is cooler than the outer core
It is made of rock
Pressure forces atoms tightly together
It contains frozen magma
Tectonic plates move on top of which layer?
Lithosphere
Inner core
Asthenosphere
Outer core
What happens when a dense oceanic plate subducts?
It floats upward
It melts instantly
It sinks and pulls the rest of the plate
It stops moving
At which type of boundary do plates move toward each other?
Divergent
Transform
Convergent
Rift
Which landforms commonly form at convergent plate boundaries?
Mid-ocean ridges
Volcanoes, mountains, and trenches
Fault lines only
Plains
New crust is formed at which type of plate boundary?
Convergent
Transform
Subduction
Divergent
The Mid-Ocean Ridge formed primarily due to:
Plates sliding past each other
Plates pulling apart and magma cooling
Plates colliding
Earthquakes
Which type of plate boundary is most associated with earthquakes?
Divergent
Convergent
Transform
Rift
Where does an earthquake originate?
Epicenter
Fault line
Focus
Mantle
What is the epicenter of an earthquake?
The point deep inside the Earth
The location of the fault
The surface point directly above the focus
The strongest seismic wave
Why does the Ring of Fire have so many volcanoes and earthquakes?
It is near the equator
The crust is thinner there
Many tectonic plates are subducting
The mantle is cooler
