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.

The geographic use of technology to view and record observations from a distance is known as ____________.
Nimfa-mama [501]

The geographic use of technology to view and record observations from a distance is known as remote sensing.

It replaces slower, steeply-priced statistics series at the ground, presenting rapid and repetitive coverage of extraordinarily huge areas for everyday programs, ranging from weather forecasts to reviews on herbal failures or climate change.

Remote sensing is the manner of detecting and tracking the physical characteristics of a place by using measuring its meditated and emitted radiation at a distance (commonly from a satellite or plane). special cameras gather remotely sensed photographs, which help researchers "experience" matters approximately the Earth.

Examples of passive far-flung sensors consist of film pictures, infrared, charge-coupled gadgets, and radiometers. active series, on the other hand, emits energy in order to experiment with objects and areas whereupon a sensor then detects and measures the radiation that is meditated or backscattered from the goal.
