Communities with cold winters often spread salt on roadways. salt lowers the melting point of water, which means slippery snow and ice will melt instead of building up on roads. while this does prevent car accidents, it poses certain problems. what is the most serious problem that could occur to local ecosystems due to road salt?
a
flooding from too much melting ice and snow

b
overpopulation because of fewer fatal accidents

c
damage to plant life because of excess salt in the soil

d
accidents involving deer and other animals that lick salt

why are construction sites considered major sources of water pollution?
a
they introduce high levels of salt into local water sources.

b
soil erosion rates accelerate dramatically, impacting water quality in streams and rivers.

c
they cause sinkholes to form, which pollute local water sources.

d
sawdust leaches into the soil, causing the water that runs into rivers and streams to be cloudy and full of particles.
