Thailand is a beautiful country which is especially famous
for tourism. It is an island country. An island is a tract of land surrounded
by water on all sides. The earth consists of 70% water. Together all the inhabitable
land mass of earth is divided in 7 continents. The United States of America is
a big country in the continent of North America. The USA is a global superpower
because it has the biggest war machine in the world. The USA navy operates 11
gigantic ships (among other ships) which can carry up to a hundred military aircrafts
each. They are called aircraft carriers. They are powered by nuclear reactors
so they are called nuclear powered carriers. Nuclear energy is a clean source
of energy which has been around for 80 years. It works on the
principle of fission between an electron and a proton. Electrons and protons
are subatomic particles. They were first discovered by a scientist named
Rutherford. Rutherford was born in a New Zealand which is also an island state
near the continent state of Australia. Australia is home to the amazing species
of kangaroos. Kangaroos are mammals who keep their young in a pouch in their
bellies until they are old enough to survive in the wild. Mammals are animals
who feed their young by milk produced in their mammary glands. Milk is an
important nutrient for the growth of mammals. It contains calcium which is
especially essential for the development of bones. There are many other
important minerals. Minerals are useful components of soil found in the earth.
There are huge reserves of minerals in Afghanistan. These reserves are
especially useful in manufacturing of weapons. Weapons are intelligent devices humans
invented to harm each other. The Russians wanted to gain access to the warm
waters of Indian Ocean so they attacked Afghanistan with air and ground forces.
Air forces consist of aircrafts equipped with weapons to attack from the air.
They use powerful engines called jet engines which enable them to gain speeds
of upwards of Mach 2. Mach number is the ratio of speed of object to speed of
sound in air. Air consists of 71% nitrogen. Nitrogen is an important part of
plants growth. They use it in the process of photosynthesis. Process industries
are industries which use different processes to manufacture an end product.
Product is also defined as the result of multiplication between two numbers.
The number of elephants in Thailand ranges between 4000-5000.
