Question

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

• impervious
• squishy
• sand
• eroded

Explanation:

"Impervious" means not allowing liquid (like water) to pass through, which matches the description of a surface water cannot penetrate. "Squishy" refers to being soft and compressible, "sand" is a granular material (water can penetrate sand), and "eroded" means worn away by natural forces—none of these fit the definition.

Answer:

impervious
