Question

Unconsolidated geological formations usually exhibit

• A. Low yield
• B. Low porosity
• C. High transmissivity
• D. Zero storage

Hint:

Unconsolidated formations (sand and gravel): \[ \boxed{ \begin{aligned} &\text{High porosity}\\ &\text{High permeability}\\ &\text{High transmissivity} \end{aligned} } \]

Answer 1

The Correct Option is C

Unconsolidated formations such as sand and gravel generally possess high porosity and permeability. As a result, they allow groundwater to move easily and usually have high transmissivity. Hence, \[ \boxed{\text{High transmissivity}} \] is the correct answer. Therefore, \[ \boxed{(C)} \]
