46
formed by tectonic activity
STRUCTURAL BASINS
47
Rocks and other material on the floor of the basin are forced
downward
48
caused by natural processes of weathering and erosion
STRUCTURAL BASINS
49
while material on the sides of the basin are
pushed up
50
happens over thousands of years
STRUCTURAL BASINS
51
is shaped like a bowl,
basin
52
# [](http://)[](http://)[](http://)[](http://) is shaped like a series of smaller bowls, stacked inside each other.
structural basin
52
usually found in dry regions
STRUCTURAL BASINS
52
3 TYPES OF STRUCTURAL BASIN
Endorheic basins Sedimentary basins Lake Basins
53
* watershed that empties into an internal body of water, not the ocean
Endorheic basins
54
have internal drainage systems
Endorheic basins
54
depression in the Earth's surface that has slowly been filled with layers of sand, rock, and other debris (sediment)
Sedimentary basins
55
often form in valleys blocked by rocks or other debris left by a landslide, lava flow, or glacier
Lake Basins
56
they don’t have enough water to drain to a stream, lake, or ocean
Endorheic basins
57
water that trickles into these types of basins evaporates or seeps into the ground
Endorheic basins
58
one of the saltiest natural body of water on Earth.
The Dead Sea
59
Its shore, about 400 meters (1,300 feet) below sea level, is Earth’s lowest dry point.
Dead Sea
60
dead sea's shore is about ----- meters below sea level
400 meters
61
The water draining into -------- -------- from its few streams does not exit the basin to a river or estuary.
Death Valley
62
63
debris acts as a dam, trapping water and forming a lake
LAKE BASINS
64
Known Endorheic Basins in the World
Death Valley, in the U.S. state of California
65
Known Lake Basins in the World
Hunza Lake in Pakistan Hunza River in Pakistan
66
was formed when an earthquake triggered a massive landslide in 2010
Hunza Lake in Pakistan
67
The debris dammed the Hunza River, in addition to killing 20 people and destroying the village of
Attabad.
68
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
69
may also be carved out by glaciers—huge masses of ice—as they move down valleys or across the land
LAKE BASINS
70
When the glaciers move, the basins they create
remain
71
During the last ice age, glaciers carved the basins of the
Finger Lakes, in the U.S. state of New York.
72
where is Finger Lakes located?
U.S. state of New York.
72
Material that fills up the basin is called
sediment fill
72
have been filled with layers of rock and organic material over millions of years.
SEDIMENTARY BASINS
73
they lived and died in ocean basins. Eventually, these ancient oceans dried up, leaving dry basins.
diatoms
73
(rock, debris, and other material that fills a sedimentary basin).
sediment
73
key sources of petroleum and other fossil fuels
SEDIMENTARY BASINS
74
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
75
one of the most productive petroleum fields in Africa.
Niger Delta sedimentary basin
76
where is Niger Delta sedimentary basin located?
in the countries of Nigeria, Cameroon, and Equatorial Guinea
77
one of the continent's largest suppliers of gas and coal.
Western Canadian Sedimentary Basin
78
where is Western Canadian Sedimentary Basin located?
North America
79
Are the largest depressions on Earth
OCEAN BASINS
80
(the edges of the continents)
Continental shelves
81
Form the sides of ocean basins and Formed through tectonic activity also
OCEAN BASINS
82
FIVE MAJOR OCEAN BASINS
Pacific Basin Atlantic Basin Indian Basin Arctic Basin Southern Basin
83
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
84
a zone of intense tectonic activity, including many earthquakes and volcanoes.
