"Depth of groundwater and distance to local lakes, rivers, and farms" is the one environmental parameter among the following choices given in the question that city officials should investigate before purchasing the neededland. The correct option among all the options that are given in the question is the first option.
The production of crops and farm animals for sale, usually with the use of modern technology: commercial farming methods.
In divergent boundaries, plates move away from one another, often causing volcanic activity. The cooled magma is able to form islands such as the ones on the Aleutian archipelago.
*I don't think any of these are actual types of mountains. <em>Arc contient </em>and <em>Andean</em> aren't even real things.
As for your second question:
There are two main types of rocks in the Earth's crust.
Granite is less dense and rises higher, usually above land in continental crust.
Basalt is denser and so it will sink lower and form oceanic crust.
However, there is a layer of sediment on top of that crust. (sand, gravel, etc.)
If y equals 32, then x would equal 6. Plugging in 32 for y is shown here
32=192/x. The opposite of division is multiplication so multiply both sides by x. You would end up with 32x=192. Finally divide both sides by 32 to get x=6.
