detail all you need to know about the subject.

AfricaAfrica is often called the “birthplace of humankind.”
That’s because human beings originated from Africa several million years ago, although humans as we
would recognize them only emerged about 200,000 years ago. Today, about 1 in 8 of the world’s population live in Africa.

THE SAHARA“Sahara” comes from the Arabic word for “desert.” The Sahara
stretches across North Africa and covers parts of 11 countries. Much of it consists of vast seas
of sand, with dunes up to 600 ft (180 m) high.

 OASISare about 90 big oases scattered across the Sahara. There
These are places where underground water comes to the surface, allowing
plants to grow.

How many people?The population of Africa is thought to be around 14 percent of the total world population. Nigeria is the most populated
African country.

A VARIED LANDSCAPEAfrica’s varied landscapes include three deserts—the Sahara (Earth’s
largest desert) in North Africa, and the Kalahari and Namib in the south. There are also large areas
of forest and grassland.

FAMOUS PLACES

The Great Rift Valley This huge valley cuts right through eastern Africa, from
Ethiopia to Mozambique. It contains a chain of vast lakes, including Lakes Tanganyika,
Victoria and Nyasa—some of the deepest lakes in the world.

Ois a circular valley, enclosed by mountain walls. It is the remains of The Ngorongoro Crater in Kenya
an ancient volcano. The crater is home to a huge variety of animals.OThe Okavango River does not flow
into the sea. Instead, it ends in a large inland swamp, known as the Okavango Delta, in Botswana. Madagascar is the world’s fourth-largest island. It is home to many unique animals, such as lemurs and fossas, which are not found anywhere else in the world.

The Red Sea divides Africa from Asia. At the northernmost end, the Suez Canal allows ships
to travel between the Red Sea and the Mediterranean.
The easternmost part of the continent is known as the “Horn of Africa,” because it is shaped like
an animal’s horn.

Bugs and
BeetlesThe word “bug” is often used to
mean any creepy-crawly, but it is actually an order of a particular kind of
insect. This order is called 82,000 species. Beetles are not the same as bugs: Hemiptera, and it has
they have their own order, 370,000 beetle species—that’s one-third of all Coleoptera. There are
known insect species.

Beetles have complete metamorphosis: they start life as a larva, then change to a pupa, and finally become an adult. Larva and pupa look different from the adult.

ELECTRIC CARS

Electric carsMost cars use gasoline, made from oil, which
causes pollution and adds to global warming. Oil supplies are running out, too. That’s why
car designers are turning to electric engines, which can use energy from cleaner sources.
HONDA FCX CLARITYThis might look like an ordinary car but it’s powered in what could be a much cleaner way. In a normal
car, the engine burns gasoline, releases energy, and makes pollution. But in this car the fuel tank is replaced by a kind of battery called a hydrogen fuel
cell. This takes hydrogen from a tank and oxygen from the air, reacts them together, and produces electricity. The only waste product is steam, so if the
hydrogen comes from a clean source there is no pollution at all.
