Determine whether the material is a rock or a mineral based on the description rock
mineral
Description
Rock or Mineral?
It often has a mottled appearance
dhe to its heterogeneous
composition
Atoms in all specimens have the
same structure and shape.
It is generally found in
crystalline form.
Every specimen varies in
terms of atomic structure.

A. It often has a mottled appearance  due to its heterogeneous  composition  - Rock

B. Atoms in all specimens have the  same structure and shape - mineral

C. It is generally found in  crystalline form -  mineral

D. Every specimen varies in  terms of atomic structure - Rock

Explanation:

A. Rocks has mottled appearance which means it can present in mottled green, white, and red because of heterogenous composition.  Rocks can be formed with varying thickness by stronger and weaker rock.

B. Minerals have ordered atomic structure and hence form same shape of all specimens.

C. Minerals have crystalline properties including Smooth, flat surfaces with regular geometric outlines.

D. Rocks are formed from the combination of different minerals and hence every specimen varies in terms of atomic structure.

Hence, the correct answer is:

A. Rock

B.  Mineral

C. Mineral

D.  Rock

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
