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.

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.
