Question

which of the following can be used to describe a surface that water cannot penetrate? squishy sand eroded impervious

Explanation:

To solve this, we analyze each option:

• "squishy" refers to being soft and compressible, not related to water penetration.
• "sand" is a material that water can penetrate (it's porous).
• "eroded" describes a surface affected by erosion, not its water - penetration property.
• "impervious" means not allowing fluid (like water) to pass through, which matches the description of a surface water cannot penetrate.

Answer:

D. impervious
