Dubai – Palm islands
When you think of Dubai, you think of the palm islands. These articificial peninsula’s are created to make the
tourism grow. The first island was completed in 2004. In total there are 3 of these islands: Palm Jumeirah, Palm
Jebel Ali and Palm Deira. Two of them were built by a Dutch company.
The islands have the shape of a palm tree: a trunk with many branches.
Phytoplankton in seas and oceans
Phytoplankton is also known as coccolithophores. These are single-celled algae, which occur in almost all seas and
oceans worldwide. Under a microscope this organism looks like a sphere covered with pineapple rings. Scientists
speak of annular calcite shields.
Such a sphere has a diameter of only a tenth of a millimeter. How special is it that you can see it from space!
Phytoplankton interlocks and can form an immense field this way and the calcite is known for its strong rebounding
The Himalaya is 2.400 kilometers long and between 150 and 280 kilometers wide.
This mountain range covers an area of approximately 600.000 km2.
Geologically the Himalaya a young mountain range, arised in the Tertiary when India and Eurasia collided with each
The Himalaya itself came up during the last two million years. India still moves 2 centimeter per year towards Asia.
Therefor the Himalaya is still growing.
In the mountains a great number of the largests rivers of Asia rise: the Brahmaputra, the Ganges and the Indus.
Not only these rivers water the Himalaya mountains but also southern Tibet and the plaines of Hindoestan are
assured of drinking water.
The hundred highest mountains of the world are all located in the Himalaya.
The Amazone is by far the longest river in South America. To be the longest river in the world the river Nile is a
The Amazone originates in Peru and debouches in Brazil in the Atlantic Ocean.
During the rainy season the river is in some places up to 40 kilometers wide. Remarkably the tributaries of the
Amazone have different colors. So there are rivers with yellow and black water.
Yellow rivers come in from the south east of the Amazone basin and take a lot of sediment with them from other
Black rivers can be found in the north of the Amazone.
The world’s largest greenhouse you can find in Almeria.
With a total area of 26.000 hectares you can speak of a giant greenhouse.
By daytime viewed from space many greenhouses packed together form a large mirror.
The greenhouses are even on the beach! This large greenhouse is home to about ten thousand small farms which
collectively produce fruits and vegetables with a total weight of 3 million tons.
Financially this means 1,2 billion euros.
Campo de Dalias is therefor called the Vegetable Garden of Europe.
The Great Barrier Reef
The Great Barrier Reef is the biggest attraction of Australia and one of the 8 world wonders. This reef is located in
the Coral Sea at the height of Queensland and consists of over 2.900 individual reefs and 900 islands. This covers
an area of approximately 334.400 km2.
It is known as the world’s largest single structure. Millions of tiny organisms called coral polyps have made this reef
structure. A lot of research on the status of the Great Barrier Reef is done.
In 2012 became clear that the total reef compared to 1985 has shrunk by half.
Storms have inflicted the greatest damage, followed by coral-eating starfish.
Approximately 10% is due to the warming of the ocean water.
The Great Barrier Reef is a World Heritage Site.
Cities of the world by night
Seen from space you can clearly see the contours of the continents shrouded in darkness. A tool to
see this clear is the light that rises from a big city. There is a lot of wattage needed to be visible at
high altitude. Incidentally this provides very beautiful pictures.
You can see how life is playing simultaniously in Western Europe, in the east of the United States and
in India. The flashing and dimming lights at these various location throughout the world form a
beautiful light show.
The Grand Canyon
In the state Arizona you will find the Grand Canyon. The Colorado River has caused this broad and
deep gorge in the landscape.
This process has taken place over millions of years’ time. Still the area is in motion, about 16cm per
The Grand Canyon is about 435 kilometers long, the width varies between 15 and 29 kilometers.
The age of the Canyon is hard to determine, some researchers think it is 70 million years, others
speak of 6 million years.
The Grand Canyon National Park is one of the first national parks. This has been accomplished under
the government of president Roosevelt.
It is one of America’s most important attractions.
The Ganges delta
With an area of over 105.000 km2 the Ganges Delta is known as the largest delta in the world.
This river is located in the south Asian region Bengal. The area consist sof more than 260 rivers,
including the Brahmaputra and the Ganges.
The Ganges Delta is characterized by a tropical climate. The average rainfall varies between 1.500
and 2.000 mm in the west and 2.000 to 3.000 mm in the east.
This makes the Delta to an extremely fertile region. It is also called the ‘Green Delta’.
Not just many people live here but also many types of panthers, tigers, elephants, birds and
