Earth
4
Earths nickname is the water planet. There is
much more water on the Earths surface than
land.
5
  • The Earth never stays the same, it is always
    changing due to weather.
  • 3 examples of this type of change are
  • hurricanes, floods, and tornadoes
  • The Earth moves when there is a volcano eruption
    or earthquake.

6
Earth the water planet, is the one where we all
are. In all our solar system, only you have life
so far! Theres sun, and air, and soil, for
living things to grow. Together with plants and
animals, they make the Earth we know.
7
Earth
8
Earth orbits the sun. A sphere is a round object
like a ball. The Earth, moon, and all the planets
are spheres. As we stand on Earth it appears that
the surface of our planet is flat. This is
because we only see a tiny part.
9
Gravity pulls everything on our planet toward the
center of the Earth. Gravity is an invisible
force that pulls all objects in our solar system
toward the sun, keeping them in orbit. It takes
365 ¼ days for the earth to orbit the sun, this
is the same as 1 year. A lunar eclipse occurs
when the full moon, the Earth and the sun are all
in line. The Earths shadow falls on the moon.
10
Gravity
11
More Gravity What goes up must come down. The sun
is sooooo BIG! It is at the very center of our
solar system. Solar means sun in Latin, therefore
solar system really means sun system. Each
planet travels in its own orbit. Some orbits are
circular shape and others are elliptical like an
egg. While the moon orbits the Earth, the Earth
and the moon together orbit the sun.
12
moon
13
The moon is the closest object in the sky to our
planet Earth. It is 240,000 miles away. It takes
the moon 28 ¼ days to make one complete orbit
around the Earth. The same side of the moon
always faces Earth. Between 1969-192 we visited
the moon 6 times.
14
There is less gravity on the moon because it is
smaller than Earth. There is no air on the
moon. Footprints left by astronauts will remain
on the surface of the moon for thousands of
years. The craters on the moon were formed by
the impact of meteors.
15
orbit
16
An orbit is the name for the path that an object
takes as it moves through space on a continuous
course around a larger object. The Earth orbits
the sun and so do all the other planets in our
solar system. The planets move in a counter
clockwise direction. It takes 1 year for the
Earth to make a complete orbit around the sun.
17
sun
18
The sun produces just the right amount of light,
heat, and energy to support life on Earth. The
sun is our nearest star. It is made mostly of
hydrogen and helium gases.
19
The core of the sun is 27 million degrees
Fahrenheit. The surface of the sun is 11,000
degrees Fahrenheit. The surface of the sun is
covered with hot, bubbling gases. The sun is the
largest object in our solar system. It is larger
than 1 million Earths. The sun is 93 million
miles away from Earth.
