Scientists recently discovered that rocks collected from the Franklin Mountains in West Texas and rocks collected from mountains in eastern Antarctica were exactly the same age. Further research showed that the rocks were chemically and geologically the same and came from the same magma source. This discovery provides evidence of —
plate tectonics
coastal erosion
global warming
ocean currents
What type of boundary would form here?
transform
convergent
divergent
subduction
On which tectonic plate do you live?
Eurasian Plate
North American Plate
South American Plate
Pacific Plate
Which of the following provides evidence that the continents were once in a position different than they are today?
similar fossil remains in South America and Africa
bears are only found in North America
major rivers form deltas
earthquakes are common on the San Andreas fault
Geothermal energy comes from--
the atmosphere
space
fossil fuels
heat inside the Earth
The type of plate boundary where two plates come together is a .....
Convergent Boundary
Divergent Boundary
Transform Boundary
Plate Boundary
A divergent boundary occurs when plates ....
Pull apart
Come together
Slide past each other
Which of the following causes Earth's tectonic plates to move?
Energy from the Sun
Magnetic Pole Reversal
Convection currents in the mantle
Faults in Mountain Ranges
How is it possible for new crust to be formed without increasing the surface area of the Earth?
Crust is destroyed at the same time it is created
New crust is underwater where it sinks
New crust breaks more easily than old crush
New crust isn't really being formed, that is just fake news!
The lithosphere is divided into pieces called ____________, which glide across the asthenosphere.
faults
tectonic plates
earth's surfaces
crust
Where do the majority of earthquakes happen?

Which of following earthquake preparedness should be observed before an earthquake hits?
Prepare a handy emergency supply kit with first aid kit, canned food and can opener, water, clothing, blanket, battery-operated radio, flashlights and extra batteries.
If possible quickly open the door for exit.
Check yourself and others for injuries, water and electrical lines for damages, for spills of chemical, toxic and flammable materials and control fires which may spread.
Keep updated on disaster prevention instructions from battery-operated radios.
