An amphitheatre-like valley,
or valley head, formed by
erosion at the head of a
glacier.
What is a Cirque?
It is like
a railroad embankment.
What is an Esker?
Unconsolidated debris or
material deposited by a
glacier, often in the form of
hills.
What is a Moraine?
When a cirque erodes leaving
only a sharp peak flanked by
nearly vertical headwall cliffs.
What is a Horned Peak?
A groove in glaciation
What is Striation?
A rock picked up by ice, carried
along and deposited many
kilometres away.
What is an Erratic?
An “egg-shaped” hill
What is a Drumlin?
A thin, almost knife-like, ridge
of rock which is typically
formed when two glaciers
erode parallel U-shaped
valleys.
What is an Arête?
A deep valley created by large
volumes of water flowing
from a melting
Continental Glacier.
What is a Spillway?
Fertile bottom of an ancient
glacier lake.
What is a Lake Plain?
This current forms when the
hot magma rises and the cool
magma falls.
What is
Convection Current?
The process in which one
tectonic plate moves under
another tectonic plate.
What is Subduction
Process whereby tectonic
plates are moving away from
each other.
What is Divergence?
The area of the Earth’s core
containing magma.
What is
the Mantle?
The location where two plates
slide past one another.
What is a Transform Plate
Boundary?
The process in which
sediments compact under
pressure and expel fluids to
become solid rock.
What is Lithification?
When magma cools and, by
gravity, minerals are
removed.
What is Crystallization?
Condition in which the Earth's
surface is worn away by the
action of water and wind.
What is Erosion?
The processes that change
Igneous rock to sediments
What are
Weathering, Erosion and
Deposition?
Matter that settles to the
bottom of a liquid
What is Sediment?
A fault that runs along the
boundary between two
tectonic plates.
What is a Transform Fault?
Wegener’s theory that the
continents float and move in a
constant motion.
What is
Continental Drift?
The number of plates that
make up the Earth’s outer
shell or crust.
What is 20?
The supercontinent that
existed in the Paleozoic era
What is the Pangaea?
Enormous pressure that
causes the Earth to uplift
and buckle.
What is Folding.
