What is acid rain?

• Acid rain is a mixture that mixes with ash

• Rainfall that is mixed with pollutants in the air

• Rainfalls only happen in one place

• Rainfall is not made of pollutants in the air or dirt

• Acid rain is always cold

Answer explanation

Acid rain refers to rainfall that has been mixed with pollutants in the air, such as sulfur dioxide and nitrogen oxides, which can lead to environmental damage. The correct choice accurately describes this phenomenon.

What is air pollution?

• Contaminated parts of water and air found in the bottom of the earth

• Pollution is when everything around you stinks and makes you sick

• Some pollution turns to non-re-useable recycled materials

• Smoke and emissions contain pollutants, such as carbon monoxide, sulfur dioxide, and nitrous oxide, which are released into the air

Answer explanation

Air pollution refers to harmful substances like carbon monoxide, sulfur dioxide, and nitrous oxide released into the air from smoke and emissions, making the correct choice the one that accurately describes these pollutants.

What are the major causes of air pollution in the United Kingdom?

• People being wasteful causes lots of smoke in our environment

• Factories, homes, and automobiles burn fossil fuels and give off smoke and emissions

• All over the world factories don't clean their areas daily which make water pollutants

• Pollutants cause no harm to the earth, factories, or homes

Answer explanation

The correct choice highlights that factories, homes, and automobiles burning fossil fuels are major contributors to air pollution in the UK, releasing smoke and emissions that harm the environment.

What causes acid rain?

• Factories, power plants, and automobiles burn fossil fuels and give off smoke and emissions

• Dark skies and rain causes automobiles to burn fuel and causes rain damage to vehicles.

• People throw away items from factories that smell bad, then it vapes into the air and cause acid rain

• The materials that power plants use to make things, changes from a liquid to a solid, causing acid rain to dry out.

Answer explanation

Acid rain is primarily caused by emissions from factories, power plants, and automobiles that burn fossil fuels. These activities release pollutants into the atmosphere, which combine with moisture to form acid rain.

How does air pollution affect human health?

• It improves respiratory health and increases energy levels

• It causes respiratory problems, heart diseases, and can worsen asthma

• It has no effect on human health

• It only affects animals and plants, not humans

Answer explanation

Air pollution negatively impacts human health by causing respiratory problems, heart diseases, and exacerbating conditions like asthma. The correct choice highlights these serious health risks associated with air pollution.

Which of the following is a natural source of air pollution?

• Volcanic eruptions

• Automobile emissions

• Factory smoke

• Burning of fossil fuels

Answer explanation

Volcanic eruptions are a natural source of air pollution, releasing ash and gases into the atmosphere. In contrast, automobile emissions, factory smoke, and burning fossil fuels are human-made sources.

What is the primary component of smog?

• Ozone

• Carbon dioxide

• Water vapor

• Oxygen

Answer explanation

The primary component of smog is ozone, which forms when pollutants react in sunlight. While carbon dioxide, water vapor, and oxygen are present in the atmosphere, they are not the main contributors to smog.
