Digestion is the process of breaking down food into usable materials, and is one function of the digestive system. The other function, absorption, makes these materials available to all cells in the body.
Matter
An alloy.
Yes, but not physically, only chemically. Part of the definition of a compound, as opposed to a mixture or solution, is that compounds can only be separated back into their respective elements through a CHEMICAL process.
This is the process of radioactive decay.

Digestion is accomplished by physically breaking down, or chemically breaking down foods.
Weathering< is the process by which materials are broken down either physically or chemically, or by a combination of both.
weathering is the breaking down of rocks to form soil. it can be caused physically chemically or biologically. physically by ice, water, and other physical conditions chemically by solution, carbonation, hydration etc.. and biologically by human activities, animals or even plants
The stomach uses chemicals along with muscles grinding the food back and forth breaking it down physically and chemically.
Chewing physically breaks food, while the saliva chemically breaks it down.
Matter
Chewing your food is only physically breaking down the substance or object by breaking it up into smaller pieces. It is only chemically broken down when it enters the stomach acids. thank u! me and my friend were arguing about it in science class.

Weathering is the process of breaking down Earth's crust.

Smaller particles of rock are produced from larger particles.
