Answer:

1. Pencil: A pencil is a writing instrument made of a graphite core encased in a wooden or plastic barrel. It is commonly used for writing, drawing, and sketching. Pencils create marks by leaving a trail of graphite on the surface, which can be easily erased or smudged.

2. Pencil Crayons: Pencil crayons, also known as colored pencils, are similar to regular pencils but with a colored pigment core. They are used for coloring, shading, and creating detailed drawings. Pencil crayons create marks by depositing colored pigment onto the surface, which can be layered and blended to achieve various shades and tones.

3. Charcoal: Charcoal is a dry, brittle, and black substance made from burned wood or other organic materials. It is commonly used for drawing and sketching. Charcoal creates marks by leaving a dark, smudgy trail on the surface, allowing for expressive and dramatic effects.

4. Chalk Pastel: Chalk pastels are dry, powdery sticks made of pigment and a binder. They are used for creating vibrant and textured drawings. Chalk pastels create marks by transferring the pigment onto the surface, which can be blended and smudged to achieve soft and blended effects.

5. Chalk: Chalk is a soft, powdery substance made of calcium carbonate. It is commonly used for writing or drawing on chalkboards or rough surfaces. Chalk creates marks by leaving a trail of powdery residue on the surface, which can be easily erased or smudged.

6. Oil Pastel: Oil pastels are similar to chalk pastels but have a waxier consistency due to the addition of oil and wax binders. They are used for drawing and coloring. Oil pastels create marks by depositing pigmented oil onto the surface, which can be blended and layered to achieve rich and vibrant effects.

These materials offer different characteristics and effects when used for drawing or marking surfaces, allowing artists and individuals to explore various techniques and styles in their creative endeavors.
