Our Changing Earth                         Table Of Contents          I.        Sun, Earth, Day and Night,                ...
The sun is very important. All the  planets go around the sun.N.Fregelette 2008                2
We live on the planet Earth. It   revolves, or goes around the               sun.N.Fregelette 2008                    3
The sun gives the Earth heat,        light and energy.                    Heat                    Light                   ...
Day and night happen because the Earth rotates, or spins around thesun. It takes the Earth 24 hours or 1    day to spin ar...
Because it spins, part of the Earthfaces the sun and part of the Earth is in a shadow. It is day time when we   are facing...
The Earth also revolves around thesun while it spins. It takes 365 days,  or 1 year to get around the sun 1               ...
The Earth travels on an invisiblecircle, called an orbit at the same      time that it is spinning.N.Fregelette 2008      ...
The Earth is tilted on an axis or invisible pole that goes through            its center.N.Fregelette 2008                ...
The way that the Earth is tilted andhow close it is to the sun when it is revolving gives us the seasons.N.Fregelette 2008...
We have 4 seasons: Spring,     Summer, Fall and Winter.N.Fregelette 2008                 11
The part of Earth that we live on is closest to the sun in the summer.    That is why it is so hot in the              sum...
The Earth is farthest away from thesun during Winter. That is why it isso cold during Winter – it is harder  for the sun t...
The moon also revolves and spins  just like Earth! When we see the   moon, it is actually just the sun reflecting or shini...
The moon that we see is always   changing. It changes because of   how much light can shine on the         moon from the s...
There are names for the way the moon looks while we see it.N.Fregelette 2008             16
When you can’t see the moon, it  is called the new moon.N.Fregelette 2008             17
When you see the whole moon,and it looks like a big circle, it is       called a full moon.N.Fregelette 2008              ...
The moon has an invisible pull  on the Earth. This pull causes    the different ocean tides.N.Fregelette 2008             ...
Low tide is when the water is far back and you go swimming.N.Fregelette 2008               20
High tide is when the watermoves up the beach and washes   away your sand castle!N.Fregelette 2008           21
Water is very important to the Earth. It is needed for all plants      and animals to live.N.Fregelette 2008              ...
The Water CycleN.Fregelette 2008                     23

There are also decomposers.     Decomposers cause plants and     animals to decay. Bacteria and       fungus are decompose...
Energy is what makes thingshappen. There are 4 natural sources or renewable sources of energy.N.Fregelette 2008           ...
Solar energy is from the sun. Itgives people and plants energy.N.Fregelette 2008                   38
Wind energy is made by the airmoving. It is caused by the heat          of the sun.N.Fregelette 2008              39
Hydropower is energy from water  that is moving, like a river or             ocean.N.Fregelette 2008               40
Geothermal energy is Earth  power. It is caused by the heat    inside the Earth’s center.N.Fregelette 2008                ...
There are nonrenewable sources ofenergy. These sources can run outwhen we use too much. Oil and gas are 2 types of energy ...
These energy sources cannot be  renewed and run out because ittakes so long for the Earth to make               them.N.Fre...
We need to be careful with our Earth if we want it to last a long              time!N.Fregelette 2008                     44
Pollution is when bad things get into our air, land and water. It hurts the Earth and can be bad for people.N.Fregelette 2...
