1.The constant variables in the following: The effect of the amount of salt on the height an egg floats
What are; material of cup. size of cup, type and size of egg, type of salt, amount of water
Deep ocean currents are powered by these three things.
What are salinity, density, and temperature?
The difference in air pressure.
What is the cause of wind?
physical or mathematical representation of an object or process
