Porous, water-saturated layers of underground bedrock, sand, and gravel that can yield economically significant amounts of water are referred to as aquifers
Aquifers are subterranean formations of bedrock, sand, and gravel saturated with water that can economically produce significant amounts of water.
<h3>What is Real Bedrock?</h3>
Bedrock is solid rock that lies beneath surface soil or gravel. Sand and other layers on the seabed are also supported by bedrock. Consolidated rock, or bedrock, is solid and strongly bonded rock. Loose-grained unconsolidated rock is often found as subsoil.
<h3>Is bedrock really rock?</h3>
The bedrock that balances the earth's crust is solid rock. While the entire state is covered by bedrock, Maine is mostly covered by a layer of surface sediment, soil, and vegetation.

Zone 9 I think if I’m not mistaken
Answer:
B. Aerobic bottom water
D. High organic productivity in the overlying oxygen rich water
Explanation:
A Shale is a sedimentary rock usually formed from silt and clay-size mineral. There are different colors of Shale. The Black Shale is formed under anaerobic conditions. This means that oxygen is deficient in the water where the Shale forms.
A little amount of organic materials is required for the formation of Black Shale and because Black Shale is formed in an environment lacking oxygen, an oxygen-rich water would not be necessary for its growth. Sediments are necessary in the formation of Black Shale.
