1
Match each type of heat transfer method with its description.
Convection
physical contact between solid objects not in thermal equilibrium
relates to density differences within fluids
does not require a medium or physical contact to transfer heat
2
Match Cause to Effect: Cause: Earth is covered by a crust that runs miles deep.
Magma at the core-mantle boundary rises and convection currents are formed.
Pressure builds up, eventually leading to an earthquake.
The mantle is insulated from the atmosphere and retains tremendous heat.
3
Match Cause to Effect: Cause: Radiogenic heat rises to heat molten magma
Magma at the core-mantle boundary rises and convection currents are formed.
Pressure builds up, eventually leading to an earthquake.
The mantle is insulated from the atmosphere and retains tremendous heat.
4
Match each type of heat transfer method with its description.
Radiation
physical contact between solid objects not in thermal equilibrium
does not require a medium or physical contact to transfer heat
relates to density differences within fluids
5
Where is the natural light display called aurora borealis located?
A
C
B
D
6
Match Cause to Effect: Cause: Tectonic plates at transform boundaries experience friction
The mantle is insulated from the atmosphere and retains tremendous heat.
Magma at the core-mantle boundary rises and convection currents are formed.
Pressure builds up, eventually leading to an earthquake.
7
Tectonic plates. The red arrows show converging, diverging, & transforming. Identify point closest to a subduction zone.
C
B
A
D
8
Magma is ________ rock
inflammable
weathered
molten
9
Which 3 geographic features are associated with a divergent boundary?
hydrothermal vents
rifts
continental mountains
ridges
10
What happens when oceanic crust collides with continental crust at a plate boundary?
Fresh oceanic crust is formed along the boundary line.
Some oceanic crust is consumed into the mantle.
The continental crust moves closer to the mantle.
The oceanic crust floats above the continental crust.
11
Earthquakes sometimes occur when
Transform boundary causes large amounts of friction between tectonic plates
A volcanic island moves away from hot spot and goes extinct
Divergent boundary abruptly reverses role to be a convergent boundary
Solid rock layer in lithosphere no longer influenced by fluid asthenosphere
12
Some underwater earthquakes shake ocean floor & cause large sea waves that destroy and threaten lives. This is called
tidal wave
landslide
avalanche
tsunami
13
Match each type of heat transfer method with its description.
Conduction
does not require a medium or physical contact to transfer heat
relates to density differences within fluids
physical contact between solid objects not in thermal equilibrium
14
Convection currents are formed in Earth’s ________, which contains magma
crust
core
mantle
15
Magma ____________ due to the heat from Earth’s interior.
cools and solidifies
dissolves and difuses
expands and contracts
16
Why are regions where convection currents diverge more suitable for building geothermal power stations?
Divergent boundaries allow heat to rise faster.
Divergent boundaries are unaffected by magma convection currents.
Divergent boundaries create mountains on which to install the stations.
Energy from magma at divergent boundaries is cleaner.
