A material that is made up of numerous adjoined crystals is described as?

• A. Crystalline
• B. Spoils
• C. Gradation
• D. Trench

Answer: (A)

Crystalline describes a solid built from atoms arranged in an orderly, repeating pattern that forms crystals. When a material is made up of many adjoined crystals, that crystal lattice extends throughout the entire mass, giving it a well-defined structure. This is common in minerals and rocks where the atoms align in a regular way. In contrast, spoils means excavated waste material, gradation refers to the range of particle sizes, and trench is a long, narrow cut in the ground—none of these describe the internal crystal arrangement. So the term that fits is crystalline.
