Name the three rock types and how they were formed
Igneous- molten lava cools and hardens into rocks
Metamorphic- formed by existing rock reserves extreme pressure and temp.
Sedimentary- Rock that is formed when pressure and chemical reactions cement sand and mud together
Name 2 main types of energy. Describe how they are different

What is energy?
The ability to do work
Describe all 7 energy forms
Thermal- total of energy moving atoms/molecules of a object.
Chem.- the energy in chem bonds of atoms/molecules that make up a substance
Electrical- energy associated with moving charged particles
Electromagnetic- energy that is reflected from an object and travels through space.
Mech.- the sum of kinetic and potential energy
Sound- form of mech. that is carried by sound waves
Nuclear- nuclear fission=release of Energy by splitting atomic nuclei apart
How do you make a magnet? Can anything be made a magnet?
Align the domains by exposing it to another magnet or charging it by electricity.

What are the three laws of electromagnetic forces
1. Like charges repel, while opposite charges attract
2. Double the amount of charges in an object= double of the electric force
3. Force between two charged objects is inversely proportional to the square of the distance between them
