Unit 7 Common Assessment Review
6.10A – Build a model to represent layers of the earth
1. Identify the names of the following sections (layers) of
the earth and describe their state of matter/what they are
made of in the boxes provided.
6.10B – Classify rocks as igneous, metamorphic, and
sedimentary
4. Fill in the missing information in the table below to describe the
different types of rocks, how they are formed, and where they are
found:
Type of Rock
in the area of a
volcano on the
surface of the earth
Magma or lava cools
down and becomes
solid rock.
metamorphic
deep within the
earth’s crust.
sedimentary
may be found in a
cliff wall, could
contain fossils.
begins as a different
type of rock, then
changes through heat
and pressure
small pieces of the
earth (including sand,
small rocks, and
fossils) form layers on
one another, with the
pressure creating solid
rock
The lithosphere is the outermost layer of the earth and overlaps the
crust and a tiny part of the upper mantle.
*HINT: Lithosphere = Land
The mantle. The crust is NOT included in the asthenosphere at all.
3. Which layer of the earth consists of liquid, molten metals?
The outer core… it is the only liquid layer of the earth.
How they are
formed
igneous
2. The lithosphere layer of the earth includes what layer or layers of
the earth?
The asthenosphere layer of the earth is the uppermost part of which
layer of the earth?
Location
5. Read the descriptions of the following rocks to decide
what type of rock they may be.
Type of Rock
How the rocks are formed
sedimentary
igneous
metamorphic
Pebbles are pushed and cemented together.
Melted rock cools and hardens quickly.
Limestone rock experiences heat and pressure.
6. Label the names of the tectonic plates in the blank rectangles
provided.
Unit 7 Common Assessment Review
6.10D – The effects of tectonic plates on the earth’s
landforms
6.10C – Identify the name and location of tectonic plates
7. The squares in the following diagrams represent the
movement of tectonic plates. What landform would result
from each example?
A ridge, rift or valley.
_________________________
A mountain range, such as the Alps
_________________________
8. The following diagram shows two tectonic plates colliding.
What will happen to the magma beneath the crust after this plate
movement occurs?
The magma will rise to the earth’s surface.
What landform might this produce?
Because this is happening between oceanic crust, it may form
volcanic islands
