material would be a better aquitrd, unconsolidate clay or sandstone rock?

Where is the water table exposed on the earth's surface?



Answer
OK, an aquifer is generally a porous substance (lots of open spaces), so:

which is more porous, the rock or the unlithified gravel?

The second is a bit trickier, because both materials are relatively non-permeable and thus may be aquitards. However, the rock can have fractures and bedding planes whereas the clay won't.

For the third question, think about an open, hand dug well. What is it like in that well where it intersects the water table? Ever dig in the sand at the beach and hit the water table? And then connect your little pond to the nearby lake?

The water table is exposed on earth in pretty well any body of water, although there are exceptions of course (a water body can be disconnected from the water table but usually isn't)

what is a food that represents the beach?

i need to come up with foods that represent the setting of my book for a project. i have to have the food, and why it represents the setting. my book takes place at the beach, in santa fe, nm, and at harvard. help!!


Answer
You can always be creative. The more creative your project, the more impressed your instructor will be. The instructor will immediately recongnize your gallant efforts to be the best!!

We have natural beaches, manmade beaches, etc. For white beaches, use table salt. To be creative and have a brown, tan, light brown or black beach add food color to your salt or rock salt. Hope this helps. or spray with food coloring (hair dye may help) but definitely food coloring.

Better yet, salt comes from the sea, lake, ocean, (water) etc . So that could probably help with your food as far as representing the setting.
