Sc. 30 - Acid Deposition and Titrations

Which of the following is NOT one of the compounds that is responsible for causing acid deposition?

• SO₂

• CO₂

• NO

• O₂

When NO, NO₂, SO₂ and CO₂ do NOT mix with water in the atmosphere and instead settle to the ground in their dry state it is known as...

• wet deposition

• dry deposition

Which of the following would be an example of an ABIOTIC effect of acid deposition?

• It decreases plants ability to absorb nutrients from the soil.

• These chemicals can build up in organisms at the top of the food chain and affect their overall health.

• It can erode coral in the oceans which affects the local food chain.

• It can cause leaching of metals (aluminum and mercury) from the soil.

When pollutants and toxins move through the food chain and begin to build up in organisms in the top trophic levels, it is called...
