What are the layers of the earths structure?
There are these things beneath us called tectonic plates. When they crash together they push the ground upwards creating a volcano. When there is a space between the 2 tectonic plates lava rushes upwards from the mantle, through the crust. The layers are in order are the crust, upper mantle, lower mantle, outer core and the inner core which is as hot as the surface area of the sun. It is 5,430 °C.

What resources do we use from beneath the earth?

 * gold
 * diamonds
 * other jewels
 * iron
 * lots of types of rocks

What are the different atmospheric layers above us?
There are lots of layers above us. The closest one is the troposphere then the stratosphere, mesosphere and thermosphere. Then comes the exosphere which thins out into the magnetosphere.

**What effect does the sun and moon have on the Earth?**
The sun will always give us light but when it turns into a white dwarf it will probably give us less light. If we didn't have the sun we wouldn't have light and if there was no light we couldn't live. The moon gives us the waves because of it's gravitational pull which pulls the waves towards it. The moon also acts as a mirror because at night the moon reflects the sun's light when it is on the other side of the world.

How can things is in our solar system affect us?
Meteors and comets can hit the Earth but they usually burn up before they hit us.This is thanks to our atmosphere. On rare occasions they have hit Earth like one which smashed up on Russia.

= WEEK 8 = = How do humans affect nature? = We do lots of things like cut down whole forests and drop rubbish into our oceans. I am personally appalled. We do do some good things but that is mostly to undo the bad things that we are doing because the bad things far outweigh the good. So in short we affect nature quite badly.
