Is Halite a native mineral?

No. The definition of a native mineral is described as, among other criterion, a natural occurring mineral consisting of a single element. Halite would not fit this definition as it is a mineral containing sodium and chloride.


How can sand be removed from well water through pebbles?

That is not an effective method. Easier and more efficient to fit a sediment filter, or if the sand is really excessive, what is called a "swirlaway filter"That is not an effective method.

Why does water move faster through gravel than through clay?

Gravel doesn't fit close together like clay soil particles do, slowing down water flow through mud. If you visualize gravel as a screen of 1/8th inch mesh and clay soil as a screen of 1/128th mesh ( 16 times smaller holes ) you can then easily understand that water flows very swiftly through the gravel screen compared to the fine particles of clay soils.


What kind of sedimentary rock is made of fragments of rocks cemented togeather by a mineral?

Clastic sedimentary rock. For a specific clastic rock....It depends on a lot of things. Grain size, sorting, roundness of clasts, and what mineral/how did it turn into cement are but a few. Best bet would be classifying based on grain size:Conglomerate - gravel sized clasts that are rounded. Matrix can range from lithic fragments to a cement of quartz to calcite to hematite etc...Breccia - as above, but clasts are angular.The above are the most likely to be described as containing "fragments of rocks", however for the below the statement is still valid--just not as obvious.Sandstone - smaller sand sized clasts whose cement may or may not be visible. Note that there are many different more specific names of sandstones based on mineralogy and percentage of matrix/cement.Mudstone/siltstone or Shale - silt/clay sized grains that are rarely visible without a hand lens.These are the most common, but there are certainly many, many more that could fit the description in your question. All of the above contain fragments of rocks, cemented by a mineral, just at different stages of weathering! Hopefully that helped!


Does acids come from hydrogen ions?

One definition for an acid is an aqueous (water) solution containing hydrogen (or hydronium) ions. Not all acids fit this definition so the answer to this question has to be "no" because it is not entirely true. A Lewis acid might not even contain hydrogen. See Link.
