Question

Read the following descriptions of rocks and layers, and identify the likelihood of each being a good aquifer by grouping them into high and low likelihoods.
LOW:
Granite (igneous rock) with very few to no cracks
Gneiss (metamorphic rock that used to be granite and underwent intense pressure)HIGH:
Unconsolidated gravel and sand
Conglomerate (sedimentary rock composed of various sizes of sediment such as pebbles and sand grains)
Sandstone (sedimentary rock composed of sand grains)

Answer 1

Answer:

Low is

1. Granite (igneous rock) with very few to no cracks.

2. Gneiss (metamorphic rock that used to be granite and underwent intense pressure

High is

1. Unconsolidated gravel and sand.

2. Sandstone (sedimentary rock composed of sand grains.

3. Conglomerate (sedimentary rock composed of various sizes of sediment

Explanation:

• Aquifers are those that are preamble and porous rocks types as the sandstone and the conglomerates and include the fractured limestone and sand and gravel the fractured volcano rock are known to be good aquifers and well-cemented sandstone and igneous and metaphoric rocks lack the fractures of good aquifers.
