What type of mine is exposed on the surface?
An open pit mine, or quarry, is exposed on the surface.
Is it true that the mechanical breakdown of food exposes a larger surface area for chemical digestion?
Yes, it is true. The reaction rate depends also on the surface area of the reactants.
What is a surface mine?
Well surface mining is when mineral deposits are located near or at the surface
Why does reducing solute particle size increase the speed at which the solute dissolved in water?
It exposes more of the solute surface to the water molecules.
Why does reducing solute particle size increase the speed at which solute dissolves in water?
It exposes more of the solute surface to the water molecules.

Is this sentence true inceasing the surface area of a reactant exposes more of it to the reaction taking place?
true

Why does reducing particle size increase the speed at which the solute dissolves in water?
It exposes more of the solute surface to the water molecules.
Why is a hamburger a greater risk for E.coli contamination than a steak?
Because the meat is ground, there is more surface area for bacteria to grow on. Because cows have an immune system, for a healthy cow the meat can be assumed sterile until cut from the animal. Cutting exposes the "sterile" meat to bacteria, which can grow on the surface and slowly into the meat. Grinding exposes more surface area for bacterial growth.

What mine starts near the surface and extends deep underground?
The type of mine is called a strip mine.
