Chapter 6 Review Question
Review Questions:
1.What is wind? Wind is the natural flow of air that we humans can detect. Wind is
created when changes in temperatures cause air to move from high to low pressure
areas. 3.What is the relationship between air density and both temperature and humidity? warm air is usually more humid than cold air 5.What type of weather does a high pressure system bring? is a whirling mass of cool,
dry air that generally brings fair weather and light winds. 7.How is the pressure gradient force related to wind speed?
Critical Thinking Questions:
1.Why is the Coriolis force different from the Northern Hemisphere to the Southern
Hemisphere?
3.Why is atmospheric wind flow considered similar to fluid flow? What implications
does this have?
5.Why does the Earth’s surface affect the direction of wind?
7.If the Earth rotated on its axis in the opposite direction, what effect would this
have on planetary pressure systems in both the Northern and Southern
Hemispheres?
Chapter 7
Review Questions:
1.What drives the surface ocean currents?
3.Why is there no significant sub-polar gyre in the Southern hemisphere?
5.What is the difference between upwelling and downwelling?
7.What drives deep ocean circulation?
Critical Thinking Questions:
1.What is the role of the ocean in Earth’s climate system? 3.In what ways are the ocean and atmosphere coupled during an El Niño event?
5.What are the early signs of a developing El Niño in the tropical Pacific Ocean?
7.What is meant by a teleconnection and what is its significance in forecasting the
impact of ENSO?
Chapter 8
Review Questions:
1.Why is it important to monitor the planet from a variety of realms and from as
many different geographic locations as possible?
3.What is the general consensus in the scientific community with regards to the
current climate change trend?
5.How long is a sun spot cycle?
7.What three variables are included in the orbital parameters of the Earth that
impact climate?
Critical Thinking Questions:
1.Describe the Maunder minimum and its possible connection to the climate of the
Little Ice Age.
3.In general, how do the Milankovitch cycles affect incoming solar radiation?
5.How does mountain building affect the atmospheric concentration of the
greenhouse gas CO2?
7.How does cloud cover affect surface air temperatures?
Chapter 9
Review Questions:
1.How can proxy data be verified?
3.Give examples of things that are commonly used as proxy data.
5.What climatic phenomena are tree ring analysis most useful reconstructing?
7.Which element and its isotopes are helpful in identifying climate change?
Critical Thinking Questions: 1.Explain why trees growing near the limits of their range are the most sensitive to
climate change and variability.
3.How do plate tectonics affect the reconstruction of climates of geologic time?
5.By about 40 million years ago, Earth’s climate began to shift toward colder, drier
and more variable conditions. What might explain this climate change?
7.Explain how it is possible for a great amount of glacial ice to cover the land even
though the climate is interglacial.
Chapter 10
Review Questions:
1.How quickly can current generation supercomputers process calculations?
3.What is essential in constructing a model?
5.What is a physical model?
7.What do global climate models have the ability to do?
Critical Thinking Questions:
1.Why are supercomputers necessary for many GCM simulations of future climate?
3.Why is it that with each successive generation of computer models, their skill
improves?
5.Explain the concept of “signal to noise” and how it is applied to studies involving
trends in climate patterns.
7.Why is there such inertia in the climate system for global average temperatures to
likely rise beyond the 21st century?
