Answers
1
Wegener proposed that the continents were once joined to form a supercontinent called...
Pangaea
Rondwana
Palanto
Rhodesia
2
Converging continental crusts (equal density) create what land form?
rift valley
mid-ocean ridge
mountain range
deep-ocean trench
3
Why is new oceanic crust less dense than older oceanic crust?
It is closer to a mid-ocean ridge.
It is cold.
It is hot.
It is moving toward a deep-ocean trench.
4
Which is not evidence of Continental drift?
Weather
Climate
Land forms
Fossils
5
Study the image: The boundary between the Pacific and Australian Plate is an example of...
Does not touch
Convergent (Subduction)
Transform
Divergent
6
T/F:Continental drift states that all continents were once joined as a single super continent.
False
True
7
Identify the Plate Boundary
No boundary

8
T/F: Oceanic crust nearer to mid-ocean ridges is younger than crust farther away.
True
False
9
Identify the Plate Boundary

10
T/F Places near plate boundaries have a higher risk of earthquakes
False
True
11
What is the land form that occurs at divergent boundaries of continental plates?
mountains
rift valley
mid-ocean ridge
deep-sea trench
12
Where does subduction occur?
On continents
Down the middle of mountain ranges.
At deep-ocean trenches
Along the middle of some ocean floors.
13
Study the image: The boundary between the African and Antarctic Plate is an example of...
Convergent (Subduction)
Transform
Divergent
Convergent (Collisional)
14
Gravity pulling more dense oceanic crust under less dense continental crust is what process?
Continental drift
Sea-floor spreading
Subduction
Plate tectonics
15
Any trace of an ancient organism that has been preserved in rock is called a?
artifact
mineral
landform
fossil
16
Plate Tectonic theory states that:
The Earth is expanding
The Earth's Continental crust ploughs along the ocean floor
Dinner plates will be outlawed in 2051
Broken parts of the lithosphere move in constant slow motion
17
T/F: If subduction occurs faster than oceanic crust can be created the ocean will expand.
false
true

Alfred Wegener first proposed that...
The Earth is expanding
Peanut butter and jelly should go together
The seafloor is spreading
The continents drift away from each other
19

20
What evidence did Wegener use to support the Theory of Continental Drift?
Similar animals lived on separated islands
The continents fit together like a jigsaw
