The image you've uploaded is a worksheet titled
"Rock Definitions" that asks students to fill in the
definition and draw a
picture for three types of rocks:
Sedimentary,
Metamorphic, and
Igneous. Since this is a learning activity, I’ll help you complete it with accurate definitions and descriptions of what to draw.

✔ Completed Worksheet:
| Word | Definition | Picture (Description) |
|---------------|------------------------------------------------------------------------------|------------------------|
|
Sedimentary | Rock formed from sediments (tiny fragments of rock, minerals, or organic matter) that are compacted and cemented together over time. Often found in layers. Examples: sandstone, shale, limestone. | Draw a rock with visible
layers (like stacked sheets), possibly showing small grains or particles. You might include tiny pebbles or sand-like texture. |
|
Metamorphic | Rock that has been changed by heat, pressure, or chemically active fluids while still solid. The original rock (called the parent rock) undergoes physical and chemical changes. Examples: marble (from limestone), slate (from shale). | Draw a rock with
wavy or folded layers, or
foliation (stripes). It may look shiny or have mineral crystals. Avoid sharp edges—metamorphic rocks often have smooth, distorted textures. |
|
Igneous | Rock formed from the cooling and solidification of magma or lava. If it cools slowly underground, it forms coarse-grained rocks (e.g., granite); if it cools quickly on the surface, it forms fine-grained rocks (e.g., basalt). Examples: granite, obsidian, pumice. | Draw a rock with
crystals or
vesicles (holes from trapped gas). It could look rough, jagged, or glassy depending on the type. For example, show small specks (crystals) or bubbles (in volcanic rocks). |

📝 Tips for Drawing:
-
Sedimentary: Use horizontal lines to show layers.
-
Metamorphic: Show wavy lines or bands to represent foliation.
-
Igneous: Add small dots (for crystals) or holes (for vesicles).

This worksheet helps students understand the
three main types of rocks and their formation processes. It's commonly used in earth science or geology lessons for elementary or middle school.
