1. The Great Barrier Reef
The Great Barrier Reef is the largest structure on Earth
made by living organisms. It is also can been seen in the space
and it is about 500,000 years old. It was made by really small
animals called coral polyp. It makes the corals together. The
coral is an apartment or a house to them. The sea water is
warm and shallow, so it is good for the animals to live and
make their own house to live in. The coral polyp creates a
shell like skeletons for their house.
The Great Barrier Reef stretches more than 1,600 miles
(2,575 kilometers) it is a little more than the distance from
Boston to Miami. It covers an area of 133,000 square miles
(344,400 square kilometers). It is on northern coast of
Australia. It is 24 kilometers wide in the north and it is over
240 kilometers wide in the south.
