The way that scientists learned about inside of the planet was by
deep sea ocean exploration
plate boundary rock analysis
tracking seismic waves
fossil records
The wave that travels fastest is the (a) .
Secondary waves can travel through liquid.
True
False
Label the layers of the Earth.
Heat flow in the (a) happens through (b) .
Our magnetism on Earth is the result of
convection currents in the outer core
convection currents in the mantle
conduction currents in the inner core
conduction currents in the mantle
Convection current is
Match the following
crust
the outermost layer of the Earth
lithosphere
brittle part of the crust & mantle
mantle
the layer between the crust and the outer core
outer core
the liquid layer surrounding the inner core
inner core
the solid innermost layer of the Earth
Evidence of continental drift included
idential rocks on different continents
ancient coral reefs in colder climates
different fossils from on different continents
Same mountain ranges found across the ocean
Alfred Wegener hypothsized that the continents were once together. He called this supercontinent (a) and this led to the idea of the theory of (b) .
Match the following.
mid-ocean ridges
long chain of mountains
deep sea threnches
at edge of continents
abyssal plains
flat areas along volcanic mountain
Label each type of plate boundary.
Seafloor spreading
is coral reef found at the ocean floor
is the pattern of similar fossils on the ocean floor
is new ocean crust being made and moves the plates
is old ocean floor subducting under new sea floor
Match the different types of stress.
Confining
rocks buried by above materials
Compression
rocks pushed together
Shear
forces moved in opposite direction
Tension
rocks pulled apart
Bending
Stress that occurs when a material is subjected to a bending force
The ways that rocks will change under stress are: rocks breaking is called (a) , rocks that return to original shape is called (b) , and rocks that do not return to orignal shape is (c) .
Match the three types of faults.
Strike-slip fault
movement is side ways/horizontal
Reverse fault
footwall drops down
Normal fault
hanging wall drops down
Elastic Rebound Theory explains why an earthquake happens: At the fault line the plates are stuck, energy builds until released/unstuck as an earthquake.
True
False
Earthquakes can happen in the following areas of plates.
transform
divergent
convergent
intraplate
Why is it hard to predict an earthquake?
It is unknown the locations that they can happen.
There is no prior evidence that it could happen.
Prior earthquake history is unimportant.
Location is easier to know but when the energy will be released is difficult to determine.
Volcanoes are located at
convergent plate boundarie
divergent plate boundaries
in the middle of a plate
strike slip plate boundaries
A volcano that has the ability to erupt at any time is (a) . A volcano that has not erupted in a long time but can is (b) . And a volcano that has not erupted in a long time and scientists believe that it will not erupt is (c) .
The (a) is the location within the Earth where an earthquake happens. The (b) is the location on the surface of the earthquake
A short time difference between the P and S waves on the seismograph means that
earthquake is close to the seismograph location
earthquake is close to the epicenter
earthquake is far to the seismograph location
earthquake is far to the epicenter
This area is known as the _ because it is an area of many volcanoes and earthquakes.
pacific ring
volcano zone
ring of volcanoes
ring of fire
