none of these features are formed at a oceanic-continental convergent boundary
What type of boundary is in this image?
convergent plate boundary

What is the correct order (starting from the surface) of Earth’s layers?
crust, outer core, inner core, mantle
mantle, outer core, inner core, crust
crust, mantle, outer core, inner core
outer core, inner core, crust, mantle
In sea-floor spreading, molten material rises from the mantle and erupts
along the edges of all the continents.
along mid-ocean ridges.
in deep-ocean trenches.
at the north and south poles.
The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle is known as _______
convection.
continental drift.
subduction.
conduction.
Most geologists think that the movement of Earth’s plates is caused by _______
convection.
continental drift.
subduction.
conduction.
The geological theory of _______ states that pieces of Earth’s lithosphere are in constant, slow motion.
subduction
plate tectonics
deep-ocean trenches
sea-floor spreading
Scientists think that convection currents flow in Earth’s
continents.
mantle.
lithosphere.
inner core.
Below is a picture of sea-floor spreading. How are the ocean crusts moving?
Converging
Diverging
Sliding
No movement
The San Andreas Fault in California is known as an active earthquake area. What type of
boundary is it?
Converging
Diverging
Transform
Sea Floor Spreading
Given this is near a divergent plate boundary, where would the oldest rock be found?
L
M
N
O
What two mechanisms do scientists think help convection currents in mantle move plates?
Ridge push and Slab pull
Normal and Reversed magnetism
Action and Reaction tectonic forces
Gravitational and Rotational pull
The asthenosphere makes up the?
Upper portion of the mantle
The lower portion of the crust
Upper portion of the outer core
Inner portion of the outer core
Which of the following is NOT caused by plate movement?
Earthquakes in California
Mt. Fuji Volcano in Japan
Grand Canyon in Arizona
Great Rift Valley in Africa
Subduction occurs when two plates separate from each other.
True
False
What is this boundary?
Convergent, Where two tectonic plates come together
Divergent, Where two tectonic plates move apart
Transform, Where two tectonic plates slide past each other
None of the above
What is true about density? (More than 1 answer)
It is the amount of matter in a specific volume
When most things are heated they become less dense
Less dense objects rise
When most thing are cooled they become more dense
More dense object sink
How is gravity important to Earth?
Generally more dense objects have more mass which causes them to have a greater attraction of gravity. This means the more dense objects attracted the more dense objects. This caused the inner layers of Earth to be most dense. The gravitational attraction is still pulling matter to the center of the Earth.
That is the most outrageously incorrect statement I have ever heard about how the layers of the Earth formed and how it is affecting Earth today.
What is the theory of plate tectonics? (More than 1 answer)
Earth is made up giant sections of the lithosphere (crust+upper mantle) that floats on top of the asthenosphere and these are considered tectonic plates
Tectonic plates meet at places called boundaries that create cracks in the surface of the Earth
Tectonic plates are slowly moving because of the convection in the liquid mantle
The Earth's crust is one rigid layer that doesn't move
All of the landforms on Earth were formed when the crust cooled and trapped a large portion of the Earth's matter inside of the Earth
What is true about the Earth's plates?
The are made of solid rock that can never be seen.
They are made of solid rock that can be seen if not covered by soil, rock, or water.
Theory that Earth's crust is divided into plates & the plates move around on the mantle
Seafloor spreading
Plate tectonics
Continental drift
Earthquakes
Shaking of the ground caused by sudden movement of large blocks of rocks along a fault
Earthquake
Volcano
Tsunami
Surface waves
What do geologists notice about the rocks along the sea floor?
They get older as they get farther away from mid ocean ridges
They get thicker closer to continents
Density is impossible to measure
Youngest parts of the crust are along the continents
Why is the upper mantle liquid, but the lower mantle is solid?
Upper mantle is hotter
Lower mantle is under higher pressure
Upper mantle is under higher pressure
Lower mantle is hotter
