Clay:
* Particle Size: Clay particles are extremely small, typically less than 0.002 millimeters in diameter. This makes them almost invisible to the naked eye.
* Texture: Clay feels smooth and fine when dry, almost like powder. When wet, it becomes sticky, pliable, and moldable.
* Structure: Clay particles are flat and plate-like, allowing them to bind together tightly. This creates a dense and cohesive structure.
* Water Absorption: Clay absorbs large amounts of water, making it soft and workable when wet. It also holds onto water well, leading to a slow drying process.
Sand:
* Particle Size: Sand particles are larger than clay, ranging from 0.0625 millimeters to 2 millimeters in diameter. They are easily visible to the naked eye.
* Texture: Sand feels gritty and rough when dry. When wet, it remains loose and grainy, though slightly more cohesive.
* Structure: Sand particles are round and irregular, making them less likely to bind together tightly. This creates a loose and porous structure.
* Water Absorption: Sand absorbs less water than clay. It drains water quickly, leading to a faster drying process.
In Summary:
The key difference lies in the particle size and structure of the materials. This difference affects their texture, water absorption, and ability to hold shape.
* Clay: Fine, smooth, sticky, pliable, cohesive, absorbs lots of water.
* Sand: Coarse, gritty, loose, grainy, porous, absorbs little water.
