1
Underneath oceans mountain ranges are created. This plate is:
Divergent
Transform
Convergent
2
When
ocean
and
continental
plates collide, which plate subducts beneath the other?
Continental, it's less dense
Neither
Oceanic, it's less dense
Oceanic, it's more dense
3
Which item does the
diagram show
to support the theory of Continental Drift?
migration patterns
sea floor spreading evidence
glacialevidence (plucking)
fossil evidence
4
Seafloor spreading occurs when two plates
Slide past each other creating earthquakes
Collide into each other
One plate subducts beneath another less dense one
Diverge from each other creating ridges
5
Land Feature: Divergent =
Mariana Trench
Himalayan Mtns
Mid Atlantic Ridge
Africa's Rift Valley
6
Sudden movement of plates is caused by
The Force.
Balanced Forces.
Unbalanced Forces.
Sus.
7
What 3 items are why Alfred Wegener's Continental Drift Theory accepted by the science community?
Hess & Holmes work had not happened yet.
People felt that there wasn't enough evidence.
People were closed minded and like diet coke.
He could not explain how the plates moved.
8
Land Feature: ?
Volcanic Mountains
Faults
Island Arcs
Folded Mountains
9
In a convection current, heat tends to:
Fall
Float
Rise
Sink
10
Which process builds up or makes more crust?
Seafloor spreading
Folded Mountain
Trenches
Subductions
11
Most of earth's volcanos are formed from
Meteorites that strike the earth.
glacial melting.
meeting of plates.
sediment build up.
12
The Oceanic Pacific plate is know as ...
Ring of Fire only
Atlantic Ocean
Transform boundary
Weddding ring
13
The name "Ring of Fire" is due to ...
Location & Depth of Earthquakes
Location of Volcanoes
Kaijuus
Movement of plates
14
Most obvious evidence for continental drift includes how similar the coast line is of these two continents:
Australia and Antarctica
S. America and Africa
N. America and S. America
Africa and N. America
15
Land features such as island arcs, trenches, volacanos, mountains, valleys, and cause earthquakes & tsunamis occur....
Africa only.
along plate boundaries.
Ring of Fire only.
anywhere on earth, it's random!

19
Plates pass by each other. What kind of plate boundary is it?
Divergent
Stationary
Transform
Convergent
20
Oceanic Plates Colliding =

Trench
Volcanic Islands
Sunduction
21
Which two processes destroys/recycles crust?
Big Mouths

Subduction
Seafloor Spreading
22
Which evidence does not support the Theory of Pangea?
Continents fits together like puzzle.
Human Bones
Fossils
Signs of plucking
23
Seafloor spreading occurs when two plates
slip pass each other creating earthquakes.
are moving away from each other creating mountain ridges.
one plate subducts beneath another less dense one.
collide into each other.
24
Rocks found along divergent boundaries are
youngest away
from the plate boundary
False - rocks are younger closer to the boundary
True - rocks are younger as you move away from the boundary
25
Rocks found along divergent boundaries are
oldest away
from the plate boundary
False - rocks are younger as you move away from the boundary
