Answers

1
What is the best evidence that the continents once fit together?
gravity from the moon moved the plates
the land all seems to fit together at the coasts
climates align with where the plates match up
Mountain Ridges showed where the plates moved together
2
Since Scientists can't travel into the earth to watch how things work. What do they do?
They create models to try to predict plate movement.
They create models to make direct observations of plates.
They just guess... its way too hard to really know.
They create a hypothesis on how it might work.
3
Which layer of Earth do the plates slide around on due to convection currents.
Outer Core
Mantle
Inner Core
Crust
4
A law...
is more of a sure thing than a theory.
can become a theory if researched long enough
describes patterns in the universe .
explains how patterns in the universe work.
5
Which is the best description of why an earthquake happens?
Rocks in the crust move.
Pressure and Heat cause rocks to move inside the earth.
Earthquakes are caused by volcanoes.
Seafloor Spreading causes earthquakes
6
Which of the following best describes the Earth's Core.
it is so hot that it vibrates as a solid
Scientists think convection currents make the core a solid
it creates a liquid iron that is super dense and heavy
the intense pressure causes the center to vibrate as a solid
7
Why is the center of the earth so dense?
Temperature melts more mass into a smaller volume
The diameter is smaller and there is less mass.
Pressure squeezes more mass into a smaller volume
The volume of the core is very large and holds a lot of mass
8
Is the chart below evidence for or against continental drift?
Against
For
neither
both
9
Use the diagram to determine what the outer core of earth is made of, the inner core is solid.
Dense Liquid
Solid Rock
Gas
Dense Solid
10
Where are the earth's plates located?
Mantle
Inner Core
Outer Core
Crust
11
There are many models of plate tectonics. Why?
There is only one true model of plate tectonics.
Some models are outdated. New things have been discovered.
The theory of Plate Tectonics keeps changing.
It is hard to know all of the variables inside the earth.
12
Rift Valley's are formed where two plates pull apart. What type of boundary is that?
Divergent
Slip-Slip
Transform
Convergent
13
What is NOT continental drift?
Pangaea
A theory by a crazy scientist named Alfred Wegner
Areas where the continents seemingly could have fit together
Continents seemingly drifting across the ocean
14
Earthquakes cause rapid changes in Earth's shape. Where are earthquakes most likely to happen.
areas where plates pull apart
Areas with high volcanic activity
transform boundaries
areas where plates meet
15
A mid-ocean ridge happens where plates pull apart. What type of boundary is that?
Transform
Convergent
Divergent
Slip-Slip
16
Which layer of the earth has density of 12.9g/cm³ and is the most dense.
Inner Core
Mantle
Upper Mantle
crust
17
Mountain Ranges form when tectonic plates collide. Which type of boundary is that?
Convergent
Slip-Slip
Transform
Divergent
18
A theory...
can become a law if researched long enough.
is just an educated guess
explains patterns in the universe.
Science is a fact and theories cannot change!
19
Seafloor Spreading occurs when new rock is pushed into old. Where is the youngest rock located?
Location 4
Location 3
Location 2
Location 1
20
Which one of these processes takes the longest time.
creating a mid- ocean ridge or mountain
Seasons
An earthquake
Photosynthesis
