the beginnings of life
earth is the third planet from the sun, with an equatorial diameter
of 7,926 miles, a polar diameter of 7,900 miles, a mass of approxi-
mately six sextillion tons, and a mean density of about 5.52 times that
of water.
scientists think that about 4,6 billion years ago, a swirling mass of
boiling hot rocks and gases, revolving around the sun, changed into a
ball of liquid rock. the ball of rock slowly cooled and a hard crust formed
on the outside. at times, the hot gases and liquid rock from inside broke
through the crust in different places. this formed mountains and cut
deep trenches that later formed the ocean beds.
geological evidence indicates that as the earth cooled, much of
the water vapour present in the atmosphere condensed. there were
violent storms and rain poured from the clouds. rivers and lakes, seas
and oceans were formed.
oxygen gas (o.) was not present in the early atmosphere, and there
were no animals yet. millions of years went by, plants began to grow
in the seas.
as plants grew, they produced oxygen. it was released by photosyn-
thesis. thus, due to this process, the first animals appeared. they first
lived in the sea, but when bigger animals developed, they crawled out
on to the land. the first creatures to come out of the water were fish
that developed lungs.
