a gravel can be broken down into different kinds of substances by physical processes. no chemical reactions are needed to separate different parts of gravel into pure substances. this is because gravel is a(n)\no compound\no element\no homogeneous mixture\no heterogeneous mixture
Answer
Brief Explanations:
Elements and compounds require chemical reactions to break - down into simpler substances. A homogeneous mixture has uniform composition throughout. Since gravel can be separated into different substances by physical processes and has a non - uniform composition, it is a heterogeneous mixture.
Answer:
heterogeneous mixture
