All are true of Wegener except:

He came home from Greenland, a hero for his theories

Heating, sinking and cooling and rising is describing

the movement in the mantle causing plates to move

All were evidence of Pangaea EXCEPT:

the Atlantic and Pacific Ocean line up

What is true both when both oceanic and continental crusts collide?

oceanic plates are denser, older, and colder and sink below

Answers

1
All are true of Wegener except:
Scientists rejected his theory of Pangaea
People believed his theory after he was dead
Wegener wrote several books about continents drifting
He came home from Greenland, a hero for his theories
2
Which is true as you go deeper in the earth's layers?
there is more oxgen
the density increases
the density decreases
the temperature decreases
3
Which plate boundary is represented in the picture?
Divergent
Convergent
Transform
None of the above
4
Heating, sinking and cooling and rising is describing
movement in the rock cycle forming igneous rocks
climate zones
the movement in the mantle causing plates to move
air pressure
5
The layer of earth that is made up of the upper mantle and the crust is the
asthenosphere
lithosphere
hydrosphere
mesosphere
6
Earthquakes occur at these plate boundaries
Convergent
Divergent
Transform
All of the above
7
The earth layer where CONVECTION CURRENTS are found.
Inner Core
Mantle
Crust
Outer Core
8
All were evidence of Pangaea EXCEPT:
separate continents fit together like a puzzle
Same reptile fossils found on S. America and Africa coasts
the Atlantic and Pacific Ocean line up
mountains on separate coasts were of the same rock/age
9
Which type of PLATE BOUNDARY occurs at the MID-OCEAN RIDGE?
Convergent
Transform
Divergent
Pangaea
10
All are evidence for Pangaea EXCEPT
fossils of plants and animals
climate clues
textbooks
glacial deposits
11
The plastic like layer, which the plates move on is called the:
hydrosphere
lithosphere
asthenosphere
lithosphere
12
What is the thinnest layer of the Earth?
outer core
crust
mantle
inner core
13
What is the driving force of moving plates?
continental drift
plate tectonics
pangaea
convection currents
14
This layer is made of a dense LIQUID
Crust
Lithosphere
Core
Mantle
15
What is true both when both oceanic and continental crusts collide?
oceanic plates are denser, older, and colder and sink below
these plates divide up creating a divergent boundary
oceanic plates are less dense, continental plates sink
the two plates of equal density force a mountain
16
Continental Drift Theory is classified as a THEORY because:
A theory is a guess or hunch about something
A theory is permanent despite any new information
It attempts to EXPLAIN the patterns, observations etc
It describes a pattern without attempting to explain it
17
Where 2 plates are separating it is called a
Convergent boundary
Earthquake zone
Mid-Ocean Ridge
Divergent boundary
18
The layers of the Earth, from the INSIDE to the OUTSIDE are...
core...crust...mantle
mantle...core...crust
crust...mantle...core
core...mantle...crust
19
This theory states that the continents have moved slowly to their current locations
Plate Tectonics
Continental Drift
Shifting Zones
Pangaea
20
What forms when two CONTINENTAL plates meet or come together?
rift valley
mountain
mid-ocean ridge
mantle
21
Where would the newer crust be due to sea floor spreading?
further away from the mid-ocean ridge
no new crust will happen during sea floor spreading
on the continental crust
Closer to the mid-ocean ridge
22
Who is credited with the theory of seafloor spreading?
Christopher Columbus
Charles Darwin
Alfred Wegener
Harry Hess
23
All are true EXCEPT:
We have drilled to the core
Converging plates can create mountains
We have not been to or drilled deeper than the crust
There is a rift valley you can walk on in Iceland
24
A fault is the location where plates are
Making earthquakes
Mountains are forced up between two continental plates
moving
staying still
25
Pangaea in Latin means:
"only land"
"large land"
"complete land"
"all land"
