Which of the following choices did Wegner give as evidence for continental drift?
Fit of continents, rock sequence, glacial evidence
Identical fossil species on different continents (both plant and animal), Antarctic climate changes
Sea-floor spreading, mid-ocean ridge, and trenches
everything but Sea-floor spreading, mid-ocean ridge, and trenches
If scientists discovered a new planet very much like Earth, where would you predict that planet would have the greatest concentration of volcanoes?
On its tectonic plates
In its oceans
On the edges of its continents in higher elevations
In the middle of its continents
Based on the diagram, which letter indicates a place where new plate material is forming?
(A) At the boundary of the continent and
ocean basin.
(B) In the middle of the ocean basin.
(C) At the boundary where the two plates are pulling apart
No new plate material is forming anywhere shown in the diagram
As you increase distance from the mid-ocean ridge, which of the following occurs?
The age of the ocean floor increases
The age of the ocean floor decreases
The age of the ocean floor is the same throughout the Atlantic Ocean
What is TRUE about the layer directly below earth's plates? (Think of silly putty activity)
It is mostly solid rock
It is mostly liquid rock
It is mostly solid and liquid rock
It is mostly slightly softened rock
Two of Earth’s plates pressed together for many millions of years. What happened if they pressed together in a place where oceanic plate material meets continental plate material?
The continental plate material was pushed downward
The oceanic plate material was pushed downward
The plates were not able to move while they were pressing together and no plate material was pushed upward
The edges of the plates were not pushed upward but they were broken into small pieces
After completing the sand and wax activity, which of the below is the best explanation of how volcanoes are created
Volcanoes are created by molten rock pushing through less dense rock material and solidifying on the surface of the Earth
Volcanoes are created by hot magma exploding out of a crater
Volcanoes are created by two plates colliding and making a mountain and then filling up with magma
What plate motion is happening at point A?
A convergent boundary where two plates collide
A divergent boundary where two plates pull apart
A transform boundary where two plates slide past each other
Not enough information is given to be able to identify the plate motion
What plate motion is happening at point B?
A convergent boundary where two plates collide
A divergent boundary where two plates pull apart
A transform boundary where two plates slide past each other
Not enough information is given to be able to identify the plate motion
Plate A and Plate B are both made of continental plate material where they touch. What will happen as the plates press together?
The edges of both plates will be pushed upward as the plates continue to move toward each other
The edges of both plates will be pushed downward as the plates continue to move toward each other
One plate will stop moving, and one plate will push upward as it continues to move toward the other plate
Both plates will stop moving
Which of the following statements is TRUE
New plate material is being added to the edges of plates, and no plate material is being removed
Plate material is being removed from the edges of plates, and no new plate material is being added
New plate material is being added to the edges of plates, and the same amount of plate material is being broken into pieces and destroyed
New plate material is being added to the edges of plates, and the same amount of plate material is being crumpled upward or recycled back into the earth’s interior
The solid rock of the cliff in this photograph is part of a continent. What is the relationship between the continent and Earth’s plates?
The continent is part of a plate
The continent is next to but is not part of a plate
The continent is on top of a layer of water that is above a plate
The continent is directly on top of a plate but is not part of the plate
Which is a better model of the Earth, a world map or a globe?
A world map is a better model of the Earth than a globe
A globe is a better model of the Earth than a world map
Whether a world map or a globe is better depends on how they will be used
What of the following is true about the size of Earth’s plates?
Some plates are as big as an ocean
Some plates are as big as the entire Earth
No plate is bigger than a football field
What of the following is true about Earth’s plates?
Earth’s plates are separated by oceans
Earth’s plates are piled on top of one another within the Earth
Earth’s plates fit closely together with the edges of the plates touching each other
Earth’s plates are surrounded by melted rock and do not touch each other
Which of the following is TRUE about the movement of earth’s plates?
They do not move because they sit on a layer of solid rock
They move along with the layer of slightly softened rock below them
They move by floating on a layer of completely melted rock below them
They do not move until the solid rock layer beneath them temporarily melts and moves
Which of the following is TRUE about when mountains have developed on Earth?
All mountains on Earth today were present when Earth formed
Mountains developed for a while after Earth first formed, but no new mountains are developing today
Mountains have been developing continuously since Earth formed, and mountains are still developing today
Mountains have only occasionally developed since Earth formed
Why does hot material rise?
Because hot air rises
Because it is less dense
Because it is more dense
Where do most earthquakes occur?
In California
On plate boundaries
In movies
