Question

environment
question 1
briefly describe how mining for minerals and metals can degrade water quality and cause acidification.
check my answer
question 2
briefly describe which environmental factors are responsible for the greenhouse effect
check my answer
question 3
describe steps that can be taken to improve water quality through water conservation.

Explanation:

Question 1: Mining exposes sulfide - containing minerals. When these react with oxygen and water, sulfuric acid is formed, leading to acidification. Also, heavy metals and other contaminants are released into water bodies, degrading water quality.
Question 2: Greenhouse gases such as carbon - dioxide (from fossil fuel burning, deforestation), methane (from livestock, landfills), nitrous oxide (from agricultural and industrial activities) trap heat in the Earth's atmosphere, causing the greenhouse effect.
Question 3: Steps include reducing water waste (fixing leaks, using water - efficient appliances), rainwater harvesting for non - potable uses, and promoting water - conserving agricultural practices like drip irrigation which can reduce runoff and pollution, thus improving water quality.

Answer:

Question 1: Mining exposes sulfide minerals which react with oxygen and water to form sulfuric acid, causing acidification. It also releases heavy metals and contaminants into water, degrading its quality.
Question 2: Greenhouse gases like carbon - dioxide, methane, and nitrous oxide are responsible for the greenhouse effect.
Question 3: Reduce water waste, harvest rainwater, and use water - conserving agricultural practices to improve water quality.
