Out of crystalline and amorphous solids, which can be cleaved easily ?

Explanation

To determine which type of solid, crystalline or amorphous, can be cleaved easily, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cleavage**: Cleavage refers to the ability of a solid to split along specific planes. This property is significant in determining how a material can be shaped or broken.

2. **Properties of Crystalline Solids**: Crystalline solids have a well-defined and ordered structure. This means that their atoms or molecules are arranged in a regular, repeating pattern. This regular arrangement leads to the formation of cleavage planes, which are areas of weakness in the crystal lattice.
