Red Cross
The Red Cross is an organisation that helps people suffering both during peace time and war. Even countries at war respect the neutrality of the Red Cross and allow its volunteers to serve the wounded. It was started by Henry Dunant and was formally launched in 1863 at Geneva, Switzerland. The Red Cross owes its name to its flag. Its flag is a red cross on a white background. May 8 is celebrated as World Red Cross Day to honour Henry Dunant's birthday.
Red giant
It is any luminous giant star with a radius between 10 and 100 times larger than that of the Sun. When a star reaches the end of its life, the temperature at its core increases, thus causing it to expand. Hence the giant size. Red giants are stars that have run out of hydrogen supply in their cores and start deriving energy from thermonuclear fusion of hydrogen outside their core.
Redwood
It is a magnificent forest tree that grows along the west coast of the U.S. Redwoods are among the world's tallest living trees measuring 60 to 85 m high. The tallest redwood tree is in California. It is 110 m high. These trees grow so close together that little sunlight reaches the ground. The wood is soft and red but it is remarkably resistant to insects and decay. In fact, the bark of the restwood tree is even fireproof because of its high water content.
Red Sea
The Red Sea is a long narrow arm of the Indian Ocean that separates the Arabian Peninsula from north-eastem Africa. It covers about 4,56,000 sq.km. The Red Sea is connected to the Mediterranean Sea by the Suez Canal, and is one of the busiest waterways in the world. It is called so probably because of the reddish brown algae that floats on its surface in summer.
