FACTS ABOUT THE SOLAR SYSTEM
Here are some facts about the solar system:
1. All the planets in the solar system follow a path or orbit around the sun in the same direction
2. The sun and all the planets ( except venus and uranus ) spin on their axes in the same direction
3. Most of the moons of the planets orbit their planets in the same direction as the planets rotate
around the sun
4. The direction of spin of the sun and the planets (except venus and uranus ) is the same as the
direction in which the planetsorbit the sun.
5. All the planets orbit the sun in the same plane. Objects that are in the same plane could all be
placed on the same flat surface, just like all the objects on a desk. That means the solar system
looks flat.

TIDES
Change in depth of the water is called a TIDE
The difference in depth of the water between high low tides is the TIDAL RANGE
Tides also cause the land to change in height through the day. This is called EARTH TIDE.
HIGH TIDES are about 12 hours apart. LOW TIDES are also about 12 hours apart. The
time between high and low tide is six hours.
EFFECTS OF TIDES
Coastal areas are more likely to have flooding at times of high tides.
volcano eruptions
earthquakes
movement of water with tides can be used to generate electricity.
Tides affect food chains, including the human food chains.
