mesosphere, lithosphere, asthenosphere
asthenosphere, lithosphere, mesosphere
lithosphere, asthenosphere, mesosphere
2
Earth's outer skin made of solid rock is called the _______
asthenosphere
crust
outer core
mantle
3
Which layer of Earth’s interior is liquid?
outer core
mantle
inner core
crust
4
The layer of the Mantle that would include the transition zone between the lower mantle and the outer core.
asthenosphere
crust
mesosphere
lithosphere
5
What process would a sedimentary rock have to encounter to become metamorphic?
compaction
heat and/or pressure
erosion
cooling of lava
6
The two processes that scientists used to determine the composition of the Earth
seismic wave measurements
digging into the mantle
temperature of the crust
rock samples
7
The hypothesis that continents were once together in a large land mass and then moved apart is called
Pangaea
Alfred Wegener
plate tectonics
continental drift
8
Subduction takes place at
the asthenosphere
deep-ocean trenches
mid ocean ridge
under mountain ranges
9
The deeper down inside the Earth,
the lower the pressure
the greater the heat & pressure
the less dense it is
the cooler it gets
10
This causes Earth's plates to move:
convection heat in the mantle
the inner core
Pangaea
continental drift
11
The thinnest layer of the Earth is:
core
crust
mantle
12
What is the correct order (starting from the surface) of Earth's layers?
mantle, outer core, inner core crust
crust, outer core, inner core, mantle
outer core, inner core, crust, mantle
crust, mantle, outer core, inner core
13
A transform boundary occurs where two plates
move toward each other
move away from each other
slide past each other
14
Long chains of mountains rising up from the ocean floor at a divergent boundary create
mid-ocean ridges
big earthquakes
convergent boundaries
subduction zone
15
Which type of rock forms from compaction of sediment?
igneous
metamorphic
sedimentary
16
Which information does a scientist need to most accurately determine the age of a rock?
amount of radioactive elements present in the rock
% of each minerals in each rock
thickness of younger rock layers that cover the rock
amount of weathering present on surface of the rock
17
These are rigid pieces of the lithosphere that float above the asthenosphere
continental drift
Alfred Wegener
fossil evidence
tectonic plates
18
The Theory that continents were once joined together and slowly broke apart was developed by
Alfred Wegener
Christopher Columbus
Marie Curie
Henry Hudson
19
A canyon on the ocean floor that bends downward is called
Mountain range
mid-ocean ridge
sea-floor spreading
deep-ocean trench
20
A divergent boundary occurs where two plates
move away from each other
move towards each other
slide past each other
21
The process of one tectonic plate sinking beneath another tectonic plate is called
subduction
mountain range
mid ocean ridge
a volcano
22
Same fossils & matching rocks on different continents. Continents “fit” are all evidence of:
Pangaea
Alfred Wegener
plate tectonics
gravitational pull
23
