Answer:
Carbon dioxide and water vapour concentrations will lead to change in temperatures.
Explanation:
- Most of the common volcanic gases include carbon dioxide, sulphur dioxide and hydrogen sulphide along with small quantities of volatile compound and elements present such as hydrogen, helium and chloride etc.
- The carbon dioxide and water vapour alter the temperature During the experiment the concentration of carbon dioxide goes up and the temperature goes down. Thus volcanic eruption often leads to global cooling.
Answer:
Hurricanes need a lot of heat to form, which is why they usually occur over tropical seas (at least 26°C).
The sun is close to the equator, providing energy to heat the ocean.
The warm ocean heats the air above it causing it to rise rapidly.
Water evaporates quickly from the hot surface of the ocean, so the rising air contains great amounts of water vapour.
The rising air starts to spin (anti-clockwise in the northern hemisphere)
The centre of the storm - the eye - is calm.
As the air rises it cools, condenses and forms towering cumulonimbus clouds.
The rapidly rising air creates an area of intense low pressure. The low pressure sucks in air, causing very strong winds.
Once the storm moves over land it starts to lose energy and fades.
