Question

The top or surface of an underground, water saturated layer of porous sediment or rock is called a(an) aquifer ground water water table table rock fraggle rock Water from the surface percolates down through the earth and raises the volume & height of the top of an aquifer. The term for this process is recharge withdrawl lateral flow artesian flow An example of a rock type that can be efficient aquifer is shale sandstone claystone basalt marble Which of the following sediments have the highest porosity? clays & silts sand & gravel Which of the following sediments have the highest permeability clays & silts sand & gravel Which of the following should be the best aquiclude? Well rounded, well sorted sand & gravel highly fractured lime stone clay, shale, igneous & metamorphic rocks the water table Which of the following should be considered aquifer "recharge"? water infiltrating from lakes & streams water infiltrating from precipitation water infiltrating from septic systems water infiltrating from melting glaciers all of the above can be considered recharge. The water table is lowered when discharge is less than recharge water quality decreases discharge is greater than recharge soil moisture is evaporated its hydraulic legs are cut shorter Conditions needed for the development of Karst Topography include a humid (wet) climate an arid (dry) climate limestone bedrock A & C B & C The porosity of earth materials is defined as their solubility in the presence of weak, naturally occurring acids the percentage of voids or pore spaces the depth of the water table their ability to transmit fluids their ability to support layers above them When too much fresh water is pumped from aquifers located near ocean coastal areas and the fresh water table becomes lower than sea level, a problem may occur called recharge suppression artesian depression saltwater incursion coastal contamination permeability schlorosis A layer of earth material that inhibits movement of ground water is a(an) aquifer well spring sink hole incursion The ability of earth materials to allow ground water to flow through them is called recharge porosity efficiency permeability filtration Icircle-shaped calcite deposits found on cave ceilings are called stalagmites stalactites.

Explanation / Answer

1.Here the option is (c) Water table.

The top saturated layer is called water table.

2.Here the option is (d) artesian flow

Water from the surface precolates down through the earth and raises the volume and height of the top of an aquifer the process is artesian flow.

3.Here the option is (b) Sand stone

Sand stone is an example rock type of an efficient aquifier.

4.Here the option is (b) Sand &gravel

Here the sand and gravel have highest porosity

5.Here the option is (b) Sand & gravel

Here the sediments with highest permeability are sand and gravel

6.Here the option is (a) well rounded,well sorted sand and gravel

7.Here the option is (e)

aquifer recharge is it takes water from lakes,springs and through precipitation.so here the option is (e) becauses it happens by all choices.

8. Here the option is (d) Soil moisture is evaporated

Water table is lowered when soil moisture is evaporated.

9.Here the option is (c) limestone bedrock

10.Here the option is (b) the percentage of voids or spaces.

11. Here the option is (c) saltwater incursion

12. Here the option is (a) aquifer

13.Here the option is (c) Spring

14.Here the option is (a) recharge

15.Here the option is (a) Stalagmites.
