Chemistry of the atmosphere - questiond 11-21

What type of radiation do greenhouse gases absorb?

Longer wavelength infrared radiation.

Name 3 greenhouse gases

Methane, carbon dioxide, water vapour.

Give two human activities that have increased atmospheric methane.

Rice farming, cattle farming.

What is global warming?

An increase in overall global temperatures.

What is climate change?

The change in long term weather patterns across the planet.

What are some of the possible side effects of climate change?

Polar ice caps melting, chances to rainfall, sea levels rising, extreme weather events, changes to ecosystems and habitats.

What is carbon footprint?

The total amount of carbon dioxide and other greenhouse gases emitted over the full life cycle of a product, service or event.

How is carbon monoxide formes and what are the dangers associated with it?

Incomplete combustion. It is a colourless and odourless toxic gas.

How are particulates formed and what are the dangers associated with it?

Incomplete combustion. Global dimming, respiratory problems, potential to cause cancer.

How is sulfur dioxide formes and what are some of the dangers associated with it?

Sulfur impurities in fossil fuels react with oxygen during combustion. It can form acid rain and respiratory problems.

How are oxides of nitrogen frowns and what are some of the dangers associated with them?

Atmospheric oxygen and nitrogen react and in the heat of a combustion engine; acid rain respiratory problems.
