Which of the following is a valid statement with relevance to groundwater?
A) in most sediments, adjacent grains fit tightly together
B) fractures are the main way groundwater moves through some rocks, such as granite
C) most groundwater occurs in underground lakes
D) most groundwater occurs in underground rivers
E) all of these
Groundwater
Water held underground in the soil or in pores and crevices in rock.
Fractures
Breaks in rock or mineral without the movement parallel to the surface of the break, often a result of stress exceeding the strength of the material.
Underground Lakes
Bodies of water that exist beneath the Earth's surface, often found in caves or formed by natural aquifers.
- Acknowledge the contributors to the dynamics of groundwater movement, notably porosity and permeability.
- Comprehend the factors leading to the development of the water table and groundwater reserves.

Final Answer :
B
Explanation :
Fractures are crucial for groundwater movement in rocks like granite, which are otherwise impermeable due to their crystalline structure. Groundwater flows through the spaces (fractures) created by cracks in these rocks, rather than through interconnected pore spaces found in more porous materials like sandstone.
