Isthmus- a narrow piece of land that
connects two larger pieces of land
Major Landforms:
The earth has 4 major types of land forms.
Mountains: Largest in height, 2 steep sides,
minimum of 1000 feet in elevation
Hills: Gradually rounded.
Plateaus: Higher than surrounding land and
usually has a cliff (kind of looks like a table
top) Only has 1 steep side.
Plains: Flat areas with very little relief (or
elevation). Costal plains have even less
elevation than Interior plains.
Secondary Landforms:
Peninsula: A continent that is surrounded
by water on 3 sides.
Archipelago: A group of closely
scattered islands.
Continental Shelf: Underwater extension
of a continent.
Water Features:
Oceans:
How many oceans are there in the world?
How many can you name?
Which one is closest to you from where
you are sitting now?
Oceans:
Pacific
Atlantic
Indian
Arctic
Pacific Ocean is the largest.
Seas, Gulfs, & Bays:
They are smaller than oceans but still salt
water.
Mediterranean Sea is the earth’s largest.
Salt water can not be consumed. It is very
difficult to turn saltwater into freshwater.
Lakes, Streams,& Rivers
Most lakes, streams, and rivers contain
freshwater.
Lakes do not have fast flowing water.
Streams- small body of water flowing
through land.
Rivers- a number of streams combined form
a river.
Early settlements were along Lakes and
rivers to tap into the freshwater source.
Brackish- where freshwater meets saltwater
(the mix of the two)
Ex. Where the Mississippi meets the Gulf of Mexico
Earth’s Highs and Lows
Earth’s Highs
The highest part on
the earth is Mt.
Everest in Nepal
(Asia) which is about
29,000 ft. above sea
level.
Earth’s Lows
The lowest point is
the Dead Sea in
Israel which is about
1,300 ft. below sea
level.
The dead sea is 9X
saltier than any body
of water in the world.
Marine life can not
survive.
People become very
buoyant (floatable) in
the dead sea.
Earth’s Depths
The deepest part of
the earth is the
Mariana Trench off
the coast of Japan in
the Pacific Ocean
which is about 36,000
ft. below sea level.
