Earth
1. Structure
  1. Crust
  2. Mantle
  3. Outer Core
  4. Inner Core
2. Crust
  1. relatively thin and rocky
3. Mantle
  1. has the properties of a solid, but can flow very slowly
4. Core
  1. made from liquid nickel and iron
5. why is there less carbon dioxide in the atmosphere?
  1. Photosynthesis - trees
Plates
1. South American Plate
2. Indian Plate
3. Australian Plate
4. Indo-Australian Plate
5. Antarctic Plate
6. African Plate
7. Eurasian Plate
8. North American Plate
9. Pacific Plate
10. Wegener, first came up with the idea of the plates and the continental drift
Atomic structures
1. -ane
  1. Single bonds
2. -ene
  1. Double bonds
Atomic structure + Periodic Table
1. Nucleus - protons+neutrons
  1. positive+negative
2. shells - electrons - negative
3. no. of protons=no. of electrons
4. top number = mass no. (Atomic mass)(No. of protons+neutons bottom number = Atomic No. (proton No.)
5. 1st shell only holds 2 electrons 2nd and all others hold up to 8
6. everything in group 1 has 1 electrons in the outer shell everything in group 2 has 2 electrons in the outer shell etc.
Ionic bonding
1. Ionic compounds have high melting and boiling points because of the many strong electrostatic forces of attraction between oppositely charged ions in the giant lattice.
  1. Ionic compounds will conduct electricity when molten or in solution because the ions are able to move freely around in the liquids
2. Ionic compounds are held together by strong forces of attraction between the oppositely charged ions
3. The structure of ionic lattices is investigated by passing X-rays through them.
Covalent
1. Bonding
  1. When two atoms share electrons to create a full shell
  2. For example, an Oxygen atom would share two atoms to two Hydrogen atoms
