Answers

1
Why is the inside of the earth still hot?
from the decay of radioactive elements
because the outer layers will not let heat escape
from huge quantities of oil and natural gas
from a nuclear process like that found in stars
2
What is the name of the outermost solid layer of the Earth?
Hydrosphere
Lithosphere
None of the above
Asthenosphere
3
All of the following are acceptable explanation for the formation of shallow seas except
Material erodes & deposits at the edge of continents
All of the above are acceptable explanations
Continents subside with additional weight
Continental crust floats higher in the asthenosphere
4
What do these things have in common: Paleomagnetism, seafloor spreading, Pangaea, hotspots
They are involved with plate tectonics
They were discovered by the Challenger
They are all used to study earthquakes
They are used to predict earthquakes & warn people of danger
5
If two oceanic plates collide at relatively fast speed with older rock, what will happen?
A large trench and earthquakes will a occur
Large earthquakes will occur
Continental mountains will form
A trench will form
6
On which side of the San Andreas fault is crust destroyed/recycled?
East side
Both sides
Neither side
West side
7
Which scientist showed that similar fossils could be found on different continents?
Richard Oldman
Lord Kelvin
Alfred Wegner
Edward Seuss
8
Which of the following statement does not correctly describe subduction zones
They are marked by the presence of deep-sea trenches
They are site where crustal plates are diverging
Are zones where old seafloor descends into the crust &mantle
They are belts of deep-focus earthquakes
9
The magnetic striping of the seafloor is considered evidence of seafloor spreading and
spreading centers in the trenches
subduction at rift valleys
periodic reversals in polarity of Earth's magnetic field
changes in Earth's axis of rotation
10
Land-based evidence of plate tectonics can be seen in:
all of the above
the alignment of mountain ranges
evidence of ancient glaciations
distribution of similar fossils on now far apart continents
11
What force moves the earth's plates
Mass flow hypothesis
Radiation
Conduction
Convection
12
When a substance is resting in buoyant equilibrium, moving neither up nor down
It displaces a volume of water which weighs slightly more
It displaces a volume of water equal in weight to its weight
It displaces a volume of water which weighs slightly less
It weighs less than the water surrounding it
13
Which of these is the most abundant on or in Earth?
Liquid water
Mantle Material
Granite rock
Basalt
14
Which list represents the main components of Earth's crust
Oxygen, silicon, uranium
Oxygen, silicon, aluminum
Oxygen, uranium, thorium
iron, aluminum, carbon
15
Which type of boundary is shown
transform boundary
continental-oceanic divergent boundary
continental-continental divergent boundary
continental-continental convergent boundary
