2. This digital story is about the Solar
System. It entails information about the
sun, characteristics of the sun, the earth,
characteristics of the earth, the universe,
inner and outer planets.

4. The universe is all of space, time and everything
that exist within, including all planets, stars,
galaxies, the contents of intergalactic space, the
smallest subatomic particles and all matter and
energy.
The Big Bang theory is the early ideology that
describes the early development of the universe.
The Solar System is embedded in a galaxy
comprised of billions of stars, the Milky Way and
those other galaxies exist outside of it.

5. The Solar System is made up of all the planets
that orbit our Sun. In addition to planets, the
Solar System also consists of moons, comets,
asteroids, minor planets, and dust and gas.

7. The inner planets are known as Terrestrial Planets
while the outer planets are known as the Gas Giants.
 Inner Planets are smaller in size in comparison to
the Outer Planets.
 Inner planets have solid surfaces while the Outer
Planets are balls of gas with no solid surfaces.
 Inner Planets have a greater density. The elements
in the inner planets are more closely packed
together causing them to be smaller and solid
whereas the Outer Planets have a lesser density ;
hence them being quite light for their large sizes.

8.  Inner Planets spin slowly, while Outer Planets spin
quickly.
 Inner Planets orbit the sun quickly, while Outer
Planets orbit the sun slowly as a result of being
millions of miles away and having much greater
distance to cover to complete an orbit.
 Inner Planets have few moons while Outer Planets
have a lot of moons.
 None of the Inner Planets has rings while the Outer
Planets have rings. The rings are actually a thin disc of
duct and rocks possibly caused by moons being
broken up or not being completely formed while
orbiting the planet.

10. The sun is the largest object in the solar system. It is
a star, a hot ball of glowing gases at the heart of our
solar system. It contains more than 99.8% of the
total mass of the Solar System. The sun is 70%
hydrogen , 28% helium and everything else
“metals” that amount to less than 2%. The sun
emits heat and light. It also emits a low density
steam of charged particles known as solar winds
which travel through the Solar System.
The Sun

11. The suns energy is used for both commercial and
domestic purposes which may but are not limited to
include:
 Solar panels for energy and electricity
 Recreational activities-Picnics in the park
 Drying of cloths
 Companies use the sun’s energy to power their
plants and machinery e.g. Drying of rice and
dyeing of fabric.

13. The earth is the third (3rd) planet from the Sun in the
Solar System. It is also the densest planet in the
Solar System, the largest of the four terrestrial
planets and the only plant known to accommodate
life.

15. The Crust- this is the portion of the earth that all life, whether it
lives on the highest point of land or in the deepest part of the
ocean resides. It is the thinnest in comparison to the other
layers.
The Mantle- this is the layer beneath the crust. It is made of
molten rock and is very dense. The crust floats on the mantle.
The convection currents of magma in the mantle causes seismic
activity in the crust making faults and shifting continents over
time.
The Core (Inner and Outer Core)- this is the densest part of the
earth. It is mostly composed of iron. This part of the earth is
very solid. The rotation of the iron core is what gives the earths
its magnetosphere, the magnetic field that protects us from
radiation allowing life to thrive.

16. Earth has a diameter of roughly 8,000 miles
(13,000 kilometres), and is round because gravity
pulls matter into a ball, although it is not
perfectly round, instead being more of an "oblate
spheroid" whose spin causes it to be squashed at
its poles and swollen at the equator.
Roughly 71 % of Earth's surface is covered by
water, most of it in the oceans. About a fifth
of Earth's atmosphere is made up of oxygen,
produced by plants.

17. Size- the diameter of the earth at the equator is
7,926 miles and its circumference or distance
around the earth at the equator is 24, 901 miles.
Composition- the composition of the earth
consists of the solid and liquid portion and the
atmosphere or gaseous portion.
Shape- the earth is spherical in shape similar to
that of the sun and moon.

18. Atmosphere- the atmosphere of the earth consists
of 79% Nitrogen, 20% Oxygen and 1% of other
gases such as Carbon Dioxide.
Force Field- the earth has two major force fields:
gravity and magnetism.
Gravity- gravity is the force at distance that
attracts objects of mass towards each other. The
force of gravity from the earth hold down our
atmosphere and oceans.
Magnetic fields-the Earths magnetic fields are the
north and south pole. The rotation of the earth and
the fact that the core of the earth is made of iron
are proof that the earth has a magnetic field.
