Ms garcias science students are studying scale models. Ms garcia had abstudent blow up a balloon to 14 centimeters in diameter. This balloon is a model sun that is approximately on ten-billionth of the size of the real sun. Consider the four circles above. Which would be the best size for the earth in a scale model of the solar system

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

elctricity and magnet is conversion to it

there are no atoms
