Which two statements about composite materials are true? they’re made up of more than one substance. they have the same or similar properties as the materials used to make them. they’re always made of metal. they’re readily available in nature.

They’re made up of more than one substance.

They have the same or similar properties as the materials used to make them.

Explanation:

They’re made up of more than one substance. True.

For example concrete is made up of a loose stones embedded in a matrix of cement.

They have the same or similar properties as the materials used to make them.True.

Concrete is robust and  can withstand high compression forces.

They’re always made of metal. False.

Concrete is not made up of a metal.

They’re readily available in nature. False.

Concrete is a man made substance. All composite materials are made by engineers they do not occur naturally in nature.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
