The document summarizes information about the structure of the Earth and plate tectonics. It includes questions and answers about: 1) The layers of the Earth and how the convecting mantle causes the tectonic plates to move. 2) The type of plate boundary (convergent, divergent, transform) that causes different surface features like mountains and earthquakes. 3) Processes like erosion, weathering, earthquakes, and volcanoes that cause changes to the Earth's surface due to plate tectonic movement. 4) How identical fossils found on separated continents provide evidence that the continents were once connected.

1. Unit Test Review

2. crust

Be able to
convecting
label the
mantle
layers of the
Earth.

3.  How do the tectonic
plates move?
• The hot molten rock in
the convecting mantle
rises, cools, and sinks
in a cycle.
• This motion causes the
plates to move toward
each other, away from
each other, slide
under, or grind past
each other.

4.  Question 1: What causes the tectonic
plates to move?
energy from the sun
ocean currents
the convecting mantle
all the above

6.  Question
2: At what kind of boundary do
mountains form?
Divergent (move apart)
Transform (slide past)
Convergent (move together)

7.  Question
3: What kind of plate boundary
causes earthquakes?
Divergent (move apart)
Transform (slide past)
Convergent (move together)

8. Movement of Tectonic Plates
Weathering and Erosion
Floods
Tsunamis
Earthquakes
Volcanoes
Glacier Movement

9.  Question4: What processes cause
changes to the Earth’s surface?
Great heat, floods, and earthquakes
Tsunamis, solar energy, and magma
Erosion, glacier formation, and
weathering
Movement of plate tectonics,
earthquakes, and floods

10.  Scientists believe
Pangea existed based
on fossil evidence
found on multiple
continents.
 The shape of
continents is also a
clue to the existence
of Pangea.

11.  Question5: If identical fossils are found
on two continents separated by an
ocean, what conclusion can you draw?
The continents were once connected
The animals could swim well
The continents are the same age
None of the above

13.  Question 6: When scientists find
fossils, what are they able to learn from
them?
Evidence of what organisms once
lived in that location
Environmental changes in that area
The approximate age of the organism
All of the above

14.  Compare rock layers
to a sandwich: Youngest layer
 The oldest layer will be
on the bottom.
 Each layer on top gets
younger and younger.
 The top layer is the most
recent, or youngest.
Oldest layer

15.  Question7: In the picture, which layer is
the youngest?
Layer 1
Layer 2
Layer 3

16. Good luck 
