Metals give up electrons to become cation or anion
galina1969 [7]
Metals usually become cations since electrons are negatively charged and when they are lost there are more protons than electrons making a positive net charge in the atom.  (cations are positively charged ions while anions are negatively charged ions)

I hope this helps.  Let me know if anything is unclear.

(1)

The health of coral colonies

The levels of carbon dioxide in the atmosphere

This is because corals are very sensitive to changes in the ocean's properties pH being included. Warmer oceans dissolves more carbon dioxide from the atmosphere hence making the waters slightly acidic. This will affect coral resulting in bleaching. This negatively affects the marine ecosystems since corals are usually at the bottom of the energy pyramid in these ecosystems.

(2)

Chlorofluorocarbons are very harmful to the environment when released into the atmosphere. They damage the ozone layer and therefore allow more UV rays from sunlight to reach the earth’s surface. They also have a  greenhouse effect causing the earth’s atmosphere to warm up. This ultimately leads to global warming and climate change.

(3)

It would allow storm systems to stall in an area

Jets streams are very significant in that they influence weather patterns across the world. They are responsible for the movement of pressure systems and global air cells and their accompanying weather patterns. Because they generally sit in between cold and warm air systems they are significant in moving these air masses around. When they are weak they cause an air system to linger including storms causing excessive flooding in an area.

(4)

Absorb and re-emit infrared radiation.

Produced by human activity

Greenhouse gases do not allow infrared radiation from the earth's surface to escape back to space. Infrared is the electromagnetic wave spectrum responsible for transferring heat energy. Therefore, when left to linger in the atmosphere, they cause the greenhouse effect. This is the reason for global warming.

(5)

Air temperature –, ice

Ocean temperature – ice, a chemical isotope of <em>foraminifera</em>

Carbon dioxide levels – a chemical isotope of <em>foraminifera</em>

Kind of plants – fossilized pollen grains

Rainfall- the rings
