seas, lakes and rivers (project in science)
TRANSCRIPT
A body of water or waterbody(often spelled water body) is any significant accumulation of water, generally on a planet's surface.
Most are naturally occurring geographical features, but some are artificial. There are types that can be either. For example, mostreservoirs are created by engineering dams, but some natural lakes are used as reservoirs. Similarly, most harbors are naturally occurring bays, but some harborshave been created through construction.
Bodies of water that are navigable are known as waterways. Some bodies of water collect and move water, such as rivers and streams, and others primarily hold water, such as lakes and oceans.
The term body of water can also refer to a reservoir of water held by a plant, technically known as a phytotelma. Our report for today is about seas, lakes and rivers.
A sea is a large body of salt water that
is surrounded in whole or in part
by land. More broadly, "the sea" is the
interconnected system
of Earth's salty, oceanic waters—
considered as one global ocean or as
several principal oceanic divisions. The
sea moderates Earth's climate and has
important roles in the water cycle, carbon
cycle, and nitrogen cycle.
Although the sea has
been travelled and explored since prehistor
y, the modern scientific study of the sea—
oceanography—dates broadly to
the British Challenger expedition of the
1870s. The sea is conventionally divided
into up to five large oceanic sections—
including the IHO's four named
oceans (the Atlantic, Pacific, Indian,
and Arctic) and the Southern
Ocean; smaller, second-order sections,
such as the Mediterranean, are known
as seas.

The Dead

called the Salt
Sea, is a salt
lake bordered
by Jordan to the
east
and Israel and
the West
Bank to the
west. Its
surface and
shores are 429

below sea
level, Earth's

A river is a natural flowing watercourse, usually freshwater,
flowing towards an ocean, sea, lake or another river. In
some cases a river flows into the ground and becomes dry
at the end of its course without reaching another body of
water. Small rivers can be referred to using names such
as stream, creek, brook, rivulet, and rill.
There are no official definitions for the generic term river as
applied to geographic features, although in some countries
or communities a stream is defined by its size. Many
names for small rivers are specific to geographic location;
examples are "run" in some parts of the United States,
"burn" in Scotland and northeast England, and "beck" in
northern England.
Rivers are part of the hydrological cycle.
Water generally collects in a river
from precipitation through a drainage
basin from surface runoff and other
sources such asgroundwater
recharge, springs, and the release of
stored water in natural ice and
snowpacks (e.g.
from glaciers). Potamology is the
scientific study of rivers while limnology is
the study of inland waters in general.
Cagayan R
iver
The Cagayan
River, also known
as the Rio
Grande de
Cagayan, is the
longest and
largest river in
the Philippine
Archipelago. It is
located in
the Cagayan
Valley region in
northern-astern
part of Luzon
Island and
traverses
the provinces of
Nueva Vizcaya,
Quirino, Isabela
and Cagayan.

The Hinatuan
Enchanted River is
a deep spring that
flows into
the Philippine Sea
and the Pacific
Ocean at Barangay
Talisay, Hinatuan,
Surigao del Sur. It
earned the moniker
"enchanted river"
from the diplomat
Modesto Farolan
who described the
river in his poem
entitled "Rio
Encantado".
Iloilo
Riv
er
The Iloilo
River located in the
Province
of Iloilo, Philip-
pines is actually
an estuary.
The river starts
in Oton at
Batiano River,
which is also an
estuary, then
traverses the Iloilo
City districts
of Lapuz, Lapaz, M
andurriao,Molo, Are
valo and the city
proper, before
emptying into
the Iloilo Strait.
A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake.
Lakes lie on land and are not part of the ocean (except for sea lochs in Scotland and Ireland), and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions.
Lakes can be contrasted with rivers or streams, which are usually flowing. However most lakes are fed and drained by rivers and streams.
Natural lakes are generally found in
mountainous areas, rift zones, and areas
with ongoing glaciation. Other lakes are
found in endorheic basins or along the
courses of mature rivers.
In some parts of the world there are many
lakes because of chaotic drainage patterns
left over from the last Ice Age.
All lakes are temporary over geologic time
scales, as they will slowly fill in with
sediments or spill out of the basin containing
them.
