from space was taken in 1960 by the trios 1
satellite.
The Rotation Of The Earth

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.

destroyed when either another animal eats it or when it

• 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.
