Determine whether each is weather or climate:
1. Michigan gets an average of 150 inches of snow per year.
2. It snowed last year on Christmas.
1. Climate
2. Weather
100
comes from evaporation and steam
water vapor / H2O
100
What event occurred in the 1850s where humans started to burn more fossil fuels and create factories and new inventions?
The Industrial Revolution
100
Why are there seasons on Earth?
because the Earth is tilted
100
Which type of heat transfer occurs in our atmosphere and in the mantle of Earth?
a. convection
b. radiation
c. conduction
a. convection
200
Where is atmospheric pressure the highest?
here on earth/ in the troposphere because there are so many air molecules pushing down on us
200
this gas comes from burning fossil fuels, deforestation, and vehicles
carbon dioxide (CO2)
200
Why is the ocean becoming more acidic?
Because the ocean is absorbing excess carbon dioxide
200
What event happens twice a year where we get exactly 12 hours of daylight and 12 hours of night?
Equinoxes (happens once in fall, once in spring)
200
Which layer of the atmosphere do we live in?
troposphere
300
What gases make up the atmosphere in the following amounts:
78% ______________
20% _______________
1% ________________
78% nitrogen, 20% oxygen, 1% water vapor/ carbon dioxide/ other
300
Which greenhouse gas is produced by livestock farming (cows) and landfills? Which gas comes mostly from fertilizers?
Methane (CH4), nitrous oxide (N2O)
300
Does Earth's climate usually change? How has it changed recently?
Earth's climate has natural variations (ice ages and warmer periods), but recently Earth's climate has been warming very rapidly.
300
What is the longest and shortest day of the year?
summer and winter solstice
300
How does the sun's heat reach Earth?
a. convection
b. radiation
c. conduction
b. radiation
400
What is the weather like the higher in altitude you go?
the air is thinner (less pressure) colder.
400
Which greenhouse gas created a hole in the ozone layer until it was banned in many countries?
CFCs (chlorofluorocarbons)
400
What are 3 causes of climate change?
deforestation, burning fossil fuels, vehicle emissions, agriculture/ increase in methane, factories/ pollution, increased release of CO2, natural processes
400
At Position A, what season is the Northern hemisphere in?
summer because the North Pole is tilted towards the Sun.
400
What is it called when many trees are removed from an area? Does this cause an increase or decrease in carbon dioxide levels?
deforestation; increase because trees aren't there to do photosynthesis and take carbon OUT of the atmosphere
500
Do large bodies of water heat and cool quickly or slowly? What does this cause in terms of climate for areas near large bodies of water?
Large bodies of water heat and cool very slowly, which causes climates in areas near the ocean or big lakes to have very moderate seasons.
500
How does the greenhouse effect work? Is it a good or bad thing?
Greenhouse effect-- heat from the sun gets trapped in Earth's atmosphere
It's a good thing because it keeps Earth warm but bad if the atmosphere is trapping too much heat.
500
List 4 "proxy records," or ways that scientists know about past climates.
coral reefs, tree rings, ice cores/ boreholes, fossils/ pollen
500
Which line causes day and night? What is this called? Which line causes a year to pass?
The red line shows Earth's rotation, which causes day and night. The blue line shows Earth's revolution around the Sun, which causes the seasons and years.
500
What is the relationship between atmospheric carbon dioxide and global temperature? Why?
Carbon dioxide is a greenhouse gas. Greenhouse gases trap heat, so the more carbon in the air, the more heat will be trapped/ global temps increase.
