GC100 Exam 2 questions well
answered to pass
What are some of the methods that scientists use to reconstruct records of past temperatures?
- correct answer ✔✔Ice cores, Ocean sediments, pollen in lake sediments and pollen, tree rings,
coral reefs
How is temperature influenced by: latitude, elevation, coastal vs continental location? - correct
answer ✔✔Low latitude is warmer with an smaller seasonal change
High latitude is cooler with larger seasonal change
Continental is bigger change and more extreme temps
Coastal is smaller change more moderate temps
Higher elevations experience colder temperatures
What is the difference between climate and weather? - correct answer ✔✔weather refers to
short-term changes in the atmosphere, climate describes what the weather is like over a long
period of time in a specific area.
What are the main factors that influence the precipitation regime in each of these: equatorial
latitudes, tropical latitudes, mid-latitudes, high latitudes? - correct answer ✔✔Equator: ITCZ,
rising air, precipitation
Tropical: sinking air, little precipitation
,Mid: Precipitation along polar front, with mid-latitude cyclones
High: Polar high pressure, sinking air, little precipitation
What is a climate classification? - correct answer ✔✔- Temperature (annual, summer, winter)
- Precipitation (annual, dry season, wet season)
- Soil moisture
- Frequency of different air mass types
How did Aristotle classify climate? - correct answer ✔✔divided world into three climes
1: Torrid Zone (equator to 23.5 N or S) too Hot to be inhabitable
2: Temperate Zone (23.5 to 66.5 N or S)
3: Frigid Zone (66.5 to N or S pole) too cold
What is the Köppen classification designed for? What is it based on? - correct answer ✔✔To
describe and explain natural vegetation boundaries
Based on monthly temperature and precipitation,
What are the six main groups in Köppen's climate system (know the letter, name, general
characteristics, and location of each)? - correct answer ✔✔(A)Tropical Humid Climates , near
equator
(B)Dry Climate, Desert and steppe climates
, (C) Mild Mid-latitude Climates, Also called "mesothermal" climates,
(D) Severe Mid-latitude Climates, Also called "microthermal" climates
(E) Polar climates, Tundra climate and ice-cap climate
(H) Highland climates, Climate influenced by elevation
Which climate group is Marquette, Michigan? - correct answer ✔✔(D) Severe Mid-latitude
Climates, Also called "microthermal" climates
When was the last ice age? - correct answer ✔✔2.6 million years ago
How has climate changed over the last century? - correct answer ✔✔average increase in Temp
1°C , (fewer cold nights and more hot days) , Ocean warming, Ice sheets losing mass, sea level
rising,
Where has warming been greatest at? - correct answer ✔✔The Arctic
How do sunspot cycles affect earth's temperature and how long are sunspot cycles? - correct
answer ✔✔they are cool, dark regions that migrate across the surface of the sun
earth warms or cools, 11 year average
What are Milankovitch cycles and roughly how long are they? (i.e., are they 20-100 million
years, 20-100 thousand years, or 20-100 years?) - correct answer ✔✔regular, natural variations
in earth's orbit.
