A sample of beach sand contains sand particles of different colors, small pebbles, and also shells. Each component contains different metals and minerals. The pebbles and shells can easily be separated from the sand.

Which term or terms could be used to describe this sample of sand?

What are your choices? This is multiple choice?

Based on the description given, there are several terms that could be used to describe this sample of sand:

1. Heterogeneous: The sand sample is said to be heterogeneous because it contains different components (sand particles of different colors, small pebbles, and shells) that are visually distinguishable from one another.

2. Composite: The sand sample can also be described as composite because it consists of multiple distinct components (sand particles, pebbles, and shells) that contribute to its overall composition.

3. Mineral-rich: Since each component of the sand sample contains different metals and minerals, it can be described as mineral-rich.

4. Sedimentary: The sand sample may be classified as sedimentary since it contains accumulated fragments of various materials (sand particles, pebbles, and shells) that have been deposited in layers over time.

To determine the correct term(s) and provide a more accurate description of the sand sample, further analysis using appropriate scientific methods like visual examination, sieving, or chemical testing may be required.
