Landforms and Natural
Resources of Canada
Grade Five Social Studies
Mr. Larson
Mountains
• A mountain is a
landform that extends
above the
surrounding terrain in
a limited area.
Mountains
• A mountain is
generally steeper
than a hill, but there
is no universally
accepted standard
definition for the
height of a mountain
or a hill although a
mountain usually has
an identifiable summit
Valleys
• A valley is a
depression with
predominant extent in
one direction. A very
deep river valley may
be called a canyon or
gorge.
Valleys
• Valleys are either U-
shaped and V-
shaped, at least with
respect of the cross
section of the slopes
or hillsides.
Hills
• A hill is a landform
that extends above
the surrounding
terrain, in a limited
area.
• They are usually
smaller and rounder
than mountains.
Plateau
• It is an area of high
land, like a mountain
or hill, but it has a flat
or table like top.
Plains
• A plain is an area of
land with relatively
low relief — meaning
that it is flat
• Prairies, grasslands,
woodlands and
deserts are all forms
of plains.
Beaches
• Beaches are
landforms consisting
of loose rock particles
- such as sand,
gravel, pebbles or
even shell fragments;
along the shoreline of
a body of water
Islands
• is any piece of land that is completely surrounded by water, above high tide, and isolated from other significant landmasses.
Islands
• There are two main
types of islands:
continental islands
and oceanic islands.
Continental islands
are close to a
continent and oceanic
islands are in the
ocean.
Coast
• The coast is defined
as the part of the land
adjoining or near the
ocean. A coastline
can have beaches,
cliffs and islands.
• A cliff is a vertical
rock exposure.
Oceans
• Oceans are major bodies
of salt water. They are
the largest body of water.
• The major oceans are the
Atlantic, Pacific, Indian
and Arctic.
• About 71% of the earth is
covered ocean, one
continuous body of water.
Gulfs and Bays
• A Bay is an area of
land that is open to
water on three sides.
• Gulf is a bay, usually
a large bay that is an
arm of an ocean or
sea. For example, the
Gulf of Mexico is the
ninth largest body of
water in the world.
Lakes
• A lake is a body of
water of considerable
size, contained on a
body of land. The vast
majority of lakes on
Earth are fresh water.
• They are smaller than
a sea.
Seas
• A sea is a large
expanse of salt water,
connected with an
ocean.
• It is usually larger
than a lake.
Rivers
• A river is a natural
waterway that transits
water through a
landscape from
higher to lower
elevations.
• Smaller forms of
rivers are streams
and creeks.
Ponds
• Ponds are old lakes.
They are also small
lakes. They are
usually full of
vegetation and fresh
water.

Natural Resources
• Natural Resources are naturally occurring
substances, that are considered valuable.
• Can you think of five natural resources
found in Canada?
Renewable Resources
• Renewable resources are generally living
resources (fish, deer, forests, etc), which
can restock or renew themselves.
• If renewable resources are used properly,
they will not run out. IF they are over-
consumed, they will diminish and
eventually run out.
Canada’s Renewable Resources
• Forests (Lumber)
• Fish (Cod)
• Beaver (fur)
• Water
• Soil
Non-Renewable Resources
• A non-renewable resource is a natural
resource that exists in a fixed amount that
cannot be re-made, re-grown or
regenerated as fast as it is consumed and
used up.
• Examples are oil, gas, diamonds, coal
Cod Fishing
• In 1993 Cod fishing was banned in
Canada because of low Cod numbers.
• This is an example of how the over-
consumption and over-fishing of a
renewable resource, has almost made the
Cod extinct.
Resources
• In the following slides, identify what the
resource is and if it is a renewable or non-
renewable resource.
• Place your answers on the worksheet
provided.
A. Renewable or Non-Renewable?
B. What type of resource?
G. What is this resource?
J. Renewable or Non-Renewable?
