Which of the following is one of the factors that causes atmospheric circulation on our
planet? - ANSWERSuneven heating of the earth's surface, rotation of the earth,
variations in the properties of air water and land
what is the recurrence interval equation? - ANSWERSR= n+1/m
Summarize how the carbon balance in the tundra biome changes over time.
What happens on both short and longer time scales? - ANSWERS- on short time scales
warming the tundra could pull more co2 from the atmosphere
- on longer time scales much more co2 could be released from thawed permafrost
- When the permafrost is intact carbon is put into the system via photosynthesis and
carbon is release via plants and soil organisms respiring. (small carbon gain)
-When the permafrostfrost starts to thaw and there is water logging, plant growth will
increase as the land gets wetter and more old carbon is respired as the active layer gets
deeper. (large carbon gain)
- When the permafrost thaws and the waterlogged is reduced due to drying pant growth
is reduced due to drier land conditions and even more old carbon is respited as the
active layer continues to deepen.
What was the global Oxidation Event and why was it such an important stage in Earth's
formation.
As part of your answer provide one piece of evidence for its occurrence (and do not say
oxygen is present in our atmosphere!) - ANSWERSThe global Oxidation Event was an
event that enabled oxygen to flourish on our planet after not existing for billions of years.
One piece of evidence for its occurrence is that it helped other gases form like methane
and CO2. It also paved the way for biodiversity and animals to thrive on earth. The
oxygen came from things like phytoplankton
Which statement relates to weather rather than climate? - ANSWERSIt is cloudy and
snowing outside.
What is the difference between basal sliding and plastic flow? - ANSWERSPlastic flow
causes a change in ice crystal shape, while basal sliding does not.
The Köppen system is the best known and most-used classification system for
presenting the general world pattern of climates Köppen established five principal
climate groups.
List and provide a one sentence description for 3 of these climate groups. -
ANSWERS1. C (humid mid latitude)- This climate is one that has more seasonal
temperature and precipitation changes.
