100
Put the following number into scientific notation: 6,090,000
6.09 x 10 to the 6th
100
Explain what would happen if there were no greenhouse effect.
The Earth would be very cold and life would not exist.
100
In what layer of the atmosphere is the ozone found?
stratosphere
100
When energy transfers through a fluid, such as air, what do we call that transfer?
Convection
100
Name the 3 non-renewable energy sources
oil, gas and coal
200
Put the following number into scientific notation: 0.00000089
8.9 x 10 to the negative 7
200
Name 3 greenhouse gases
carbon dioxide, methane, water vapor
200
What are 2 major things that humans are doing to increase greenhouse gases?
burning fossil fuels and deforestation
200
Describe what type energy transfer is occurring when a lizard sits out on a rock.
radiation-from the sun conduction-from the rock convection-from the air
200
What is the definition of a non-renewable resource?
A resource that cannot be replaced as fast as we use it.
300
Put the following number into standard notation: 6.9 x 10 to the negative 5
0.000069
300
What is the difference between weather and climate?
Weather is day to day, climate is the average over time
300
Draw a graph that shows the general relationship between temperature and carbon dioxide in the Earth's atmosphere.
The general trend is that as carbon dioxide increases so does temperature
300
What is the difference between heat and temperature?
Heat is total energy whereas temperature is average energy
300
Draw a general flow map that shows how electricity gets from the sun to your cell phone.
sun-plants-coal-turbine-electricity (phone)
400
Conversion factor: 1000 m = 1 km, Convert 6.2 km into m.
6,200 m
400
Look at the climograph, is this an area that is near a body of water? How do you know?
Yes, because the temperatures don't change much over the year
400
Describe how the orographic effect changes the climate of a region.
Causes the windward side of the mountain to be cool and moist and the leeward side to be warm and dry
400
Explain why someone in the thermosphere (where the temperature is very hot) will freeze to death without a space suit
Because the air particles are moving so fast and the density is so low the air particles will most likely not hit the person. If the particles don't hit the person then the energy cannot be transfered
400
Which of the following resources use a turbine to generate electricity: nuclear hydropower wind coal
nuclear hydropower wind coal
500
Conversion factors: 1000 m = 1 km, 3 ft = 1 yd, 1 mi = 1.61 km, 100 cm = 1 m, Convert 5.6 mi to cm
901,600 cm
500
Look at the climograph, is this in the Northern or Southern hemisphere? How do you know?
Southern, because winter is during June, July and August
500
Explain how ice cores can be used to determine the climate of the past.
Gases and particles are trapped in the ice that give evidence about the Earth's climate
500
Explain how wind flows from the ocean to land during the day
The sand absorbs and then transfers more of the suns energy than the water. The air above the sand heats up and the molecules move faster (become less dense). Because they are less dense, the air rises. The cool dense air that is over the water moves in to replace the hot air that rose = wind!
