Facts About The Earth
• The Earth is more than four billion years old.
• More than six and a half billion people inhabit
The Earth.
• The Earth is the biggest of all terrestrial planets.
• The diameter of Earth is 7,926 miles.
• The circumference measured around the equator
is 24,901.
• About 30% of Earths surface is covered with land
while about 70% is covered with oceans.
Facts About The Earths Atmosphere
• The Earth’s Atmosphere is 77% nitrogen,21% oxygen
that has trace’s of carbon dioxide and water.
• The Earths Atmosphere water recourse's ecosystems
and human communities are effected.
• The Earths tempeature,weather,atmosphere and many
other factor’s are just right to keep us alive.
• The Atmosphere becomes thinner until it gradually
reach's space. It is divided into five layers.
• Most of the weather and clouds are found in the five
layer’s.
More Facts About The Earth
• The Earth was made with tiny rocks to create the
birth of The Earth.
• The Earth is the only planet known to have
life,land,water,air and sun so human beings can
live on The Earth .
• Earth is the only planet whose English name does
not derive from Greek/Roman mythology.
•
Special Facts About The Earth
• The Earth is the only planet that has water on
it’s surface.
• The Earth is traveling through space at a speed
of almost 18 miles(50 km) per second.
• The Earth weigh’s about 6 trillion tons
• The Earths first picture of the worlds weather
from space was taken in 1960 by the trios 1
satellite.
The Rotation Of The Earth
• The earth rotates about an imaginary line that passes
through the North and South Poles of the planet.
• The line is called the axis of rotation.
• It takes 1 day to rotate on it’s axis and that’s what
cause’s day and night.
• Earth travels about 1 / 365 of the way around the sun
during one day
• There is a small difference between solar time and
sidereal time.
• It takes The Earth 1 year to revolve around the sun.
• The Axis Of Rotation cause’s the season’s.
Did You Know…
• Every 4 years, we have 1 extra day on February
29.This is called a leap year.
• There are millions of other galaxy's in the
universe.
• If The Earth were as big as Jupiter, it would fill the
Earthrise image.
• Volcanoes, Earthquakes and heat from inside The
Earth make’s it move.
• There is enough gold dissolved in sea water to
give each person on the planet about 2 pounds.
Facts About The Earths Moon
• The Earths moon’s name is Luna.
• Luna is a beautiful world that lies some 384,400 kilometers
from The Earth.
• The Moon takes about 27 days (27 days, 7 hours, 43
minutes, 11.6 seconds) to go all the way around The Earth
and return to it’s starting position.
• The Moon is 4.5 billion years old.
• Looking down from the north pole we would see the Moon
orbiting counterclockwise from west to east.
• The Moon is about 250,000 miles from The Earth.
• The moon orbits Earth at an average speed of 2,288 miles
per hour.
The Earths Stars
• All stars were made from clouds of cold molecular
hydrogen that gravitationally collapse.
• If you could collect all the stars together and put them
in piles, the biggest pile, by far, would be the red
dwarfs.
• The Red Dwarfs are stars with less than 50% the mass
of the Sun.
• Some stars come in many pairs.
• there are 200-400 billion stars in our galaxy.
• The closest star to Earth is Proxima Centauri, located
4.2 light-years away.
Facts About Fossils
• Most fossils are invertebrates.
• When an animal or plant dies it is usually completely
destroyed when either another animal eats it or when it
decays.
• Fossils are the naturally preserved remains or trace’s of
ancient life that lived in the geologic past.
• The kinds of fossils found in rocks of different ages differ
because life on Earth has changed through time.
• Most fossils are the remains of extinct organisms; that is,
they belong to plants or animals that are no longer living
anywhere on Earth.
• Fossils represent the remains or traces of once-living
organisms.
