Choose three possible pollutants to ground water.
castortr0y [4]

Answer:

  • fertilizer/chemicals
  • oil/gas spills
  • animal feces

Explanation:

  • Fertilizers and chemicals are important contaminants of water and enter ground both directly and indirectly. In the case of Karst landscapes, the contaminated water infiltrates into the groundwater through underground streams or percolation.
  • Oil and gas spills also pose a serious problem for groundwater contamination as they can pollute aquifers near fracking zones and other oil extraction areas.
  • Animal feces are more of a problem in the modern age due to large-scale commercialized animal farms. Unless the waste from these facilities is controlled, it can runoff into fields and rivers and eventually seep into groundwater reserves.

Why do large jet airplanes fly in the stratosphere?
ella [17]

Answer:

The main reason airplanes fly in the stratosphere is because this is where the least amount of turbulence is found. In addition, because the stratosphere is very dry, there are fewer clouds in this layer, making for a much smoother ride overall.

HOW CAN SUBSIDENCE LEAD TO THE FORMATION OF SEDIMENTARY ROCK?
worty [1.4K]
<span>Subsidence changes the base level allowing further sedimentation. Augmented burial results in ever cumulative heat and pressure as the sediments are compressed. For sandstones, the augmented pressure of compaction outcomes in heaviness solution of the quartz grains. The silica unconfined from this procedure forms quartz overgrowths inside the pores efficiently cementing the sand grains together. If the procedure lasts, the sandstone will finally form quartzite.</span>
