Tripoli is the capital of Libya, a country
in northern Africa. The city lies on a
piece of rocky land overlooking the
Mediterranean Sea. It is Libya’s largest
city and main seaport.
Shipping oil and other goods through
the port brings money to Tripoli. The
city is also Libya’s main center of business
and industry.
In ancient times the city was called Oea.
People called the Phoenicians founded it
in the 600s BC. It was one of the three
main cities in the Phoenician region
called Tripolitania, which means “Three
Cities.” The city became part of the
Roman Empire and later the Byzantine
Empire.
Muslim Arabs conquered Tripoli and the
rest of Libya in about AD 645. The Turkish
Ottoman Empire ruled Libya from
1551 until 1911. Then Italy and, later,
Great Britain controlled Libya. In 1951
Libya became an independent country
with Tripoli as its capital.

Tropics
The region of Earth’s surface that is
closest to the equator is called the tropics.
Two imaginary lines that circle the
globe mark the boundaries of the tropics.
The line called the Tropic of Cancer
marks the northern edge. Its latitude
(distance from the equator) is 23° 27' N.
The line called the Tropic of Capricorn
marks the southern edge. Its latitude is
23° 27' S.
The tropics are the only part of Earth
where the sun sometimes shines straight
down. Because the sunlight is so strong,
the tropics are generally warmer than
other parts of Earth. Tropical temperatures
are warm or hot throughout the
year. The temperatures do not change

greatly, but winds and rain bring different
types of weather. Most tropical
places experience wet and dry seasons.
Areas closest to the equator are the wettest.
A great deal of rain falls year-round.
Dense rain forests cover the land. The
largest tropical rain forests on Earth lie
in Brazil and in parts of Africa.
The climate is drier in tropical regions
that lie farther north and south of the
equator. In these regions there are one or
two dry seasons each year. The forests
may be deciduous, meaning that the
trees shed their leaves during the dry
periods. Savannas, or grasslands with
scattered trees, are also common.
The driest parts of the tropics lie near the
northern and southern edges.Here the
dry season is long. Few trees grow. Shrubs
and low grasses cover the land.Two of
Earth’s big deserts, the Sahara and the
Kalahari, lie on the edges of the tropics.
Many plants and other products that
people value come from the tropics. Some
of these are bananas, coffee, cocoa, tea,
rubber, spices, nuts, and tropical wood.

Trout
Trout are a kind of fish that many
people like to catch and eat. Trout are
closely related to salmon. Most species,
or types, of trout are freshwater fish.
Many live in clear, cool streams and
lakes. Some types live in the ocean but
return to freshwater to breed.
There are two main groups of trout species:
black-spotted trout and speckled
trout. The species of black-spotted trout
include rainbow, cutthroat, and golden
trout. Black-spotted trout range in color
from silver, brown, or dark gray to shiny
green, blue, red, or gold. They all have
small black spots on the back.
The species of speckled trout include
brook, Dolly Varden, lake, and bull
trout. Some speckled species are also
called chars. Speckled trout have lighter
spots on a darker body. Many speckled
species have pinkish or red spots, especially
on the underside.
The brown trout is separate from the
black-spotted trout and speckled trout.
It has a brown body with black spots.
The rainbow trout is popular with people
who fish for sport.
BRITANNICA STUDENT ENCYCLOPEDIA Trout 99
Trout vary in size, depending on the
species. Many species of trout are about
1 foot (30 centimeters) long.
Trout eat insects, small fish, and eggs of
other fish. Many species spawn, or
reproduce, in the spring or the fall. The
females bury their eggs in gravel nests
that they dig in the bottom of streams.
The eggs hatch after two or three
months.
