❖ Can be oval or circular in shape
❖ Some are filled with water
is an area drained by a
river and all of its
tributaries
RIVER DRAINAGE
BASINS
3 The Major Types of Basins:
✓ River Drainage Basins
✓ Structural Basins
✓ Ocean Basins
(a river or
stream flowing into a
larger river or lake)
tributaries
made up of different
watersheds
RIVER DRAINAGE
BASINS
made of entire river system or an area drained by a river and its tributaries
watersheds
a small version of a river basin
Watershed
Every ——- and —— has its own watershed that
drains to a larger stream or wetland
stream and tributary
area of land covered by a shallow water or
saturated by water

STRUCTURAL
BASINS
Rocks and other
material on the floor
of the basin are
forced
downward
caused by natural processes
of weathering and
erosion
STRUCTURAL
BASINS
while material on the
sides of the basin
are
pushed up

3 TYPES OF STRUCTURAL BASIN
Endorheic basins
Sedimentary basins
Lake Basins
- watershed that empties into
an internal body of water,
not the ocean
Endorheic basins
have internal drainage
systems
Endorheic basins
depression in the Earth’s
surface that has slowly
been filled with layers of
sand, rock, and other
debris (sediment)
Sedimentary basins
often form in valleys blocked by rocks or
other debris left by a landslide, lava flow, or
glacier
Lake Basins
they don’t have enough
water to drain to a
stream, lake, or ocean
Endorheic basins
water that trickles into
these types of basins
evaporates or seeps into
the ground
Endorheic basins
one of the saltiest natural body
of water on Earth.
The Dead Sea
Its shore,
about 400 meters (1,300 feet)
below sea level, is Earth’s lowest
dry point.
Dead Sea
dead sea’s shore is about —– meters below sea level
400 meters
The water draining into ——– ——– from its few streams does
not exit the basin to a river or estuary.
Death Valley
debris acts as a dam,
trapping water and
forming a lake
LAKE BASINS
Known Endorheic Basins in
the World
Death Valley, in the U.S. state
of California
Known Lake Basins in the
World
Hunza Lake in Pakistan
Hunza River in Pakistan
was formed when an
earthquake triggered a
massive landslide in 2010
Hunza Lake in
Pakistan
The debris dammed the
Hunza River, in addition to
killing 20 people and
destroying the village of
Attabad.
this river continues to
flow into the lake basin, and
many geologists and villagers
worry the basin won’t be
strong enough to hold the water
The Hunza River in Pakistan
may also be carved
out by glaciers—huge
masses of ice—as they
move down valleys or
across the land
LAKE BASINS
When
the glaciers move,
the basins they create
remain
During the last ice age, glaciers carved the basins of the
Finger Lakes, in the U.S. state of New York.
where is Finger Lakes located?
U.S. state of New York.
Material that fills up the
basin is called
sediment fill
have
been filled with layers of
rock and organic material
over millions of years.
SEDIMENTARY
BASINS
they lived and died in ocean basins. Eventually, these
ancient oceans dried up, leaving dry basins.
diatoms
(rock, debris, and other
material that fills a
sedimentary basin).
sediment
key sources of petroleum and other fossil fuels
SEDIMENTARY
BASINS
remains were crushed under billions of tons of sediment
fill, over millions of years. In the right conditions, the pressure
of the sediment fill turns the diatom remains into
petroleum
one of the most
productive petroleum
fields in Africa.
Niger Delta sedimentary basin
where is Niger
Delta sedimentary basin located?
in the countries of Nigeria,
Cameroon, and Equatorial
Guinea
one of
the continent’s largest
suppliers of gas and
coal.
Western Canadian Sedimentary Basin
where is Western Canadian Sedimentary Basin located?
North America
Are the largest
depressions on Earth
OCEAN BASINS
(the edges of the
continents)
Continental shelves
Form the sides of
ocean basins
and Formed through
tectonic activity also
OCEAN BASINS
FIVE MAJOR OCEAN BASINS
Pacific Basin
Atlantic Basin
Indian Basin
Arctic Basin
Southern Basin
is the largest ocean basin in the world. It is more than
155 million square kilometers (59 million square miles)all of the
continents could fit into
Pacific Ocean
a zone
of intense tectonic activity, including many earthquakes and
volcanoes.
