Conduction, Convection, Radiation
How does thermal energy move in terms of temperature?
Thermal energy always moves from an object with a higher temperature to an object with a lower temperature.
What is the only radiation that human eyes can detect?
Visible Light
The specific heat of water is (higher/lower) than the specific heat of sand?
Meaning that land heats up and cools down (slower/faster) than water.
HIGHER (6X higher)
FASTER
Wind is the movement of air from an area of high pressure to an area of low pressure.
What kind of graph do you create if all of your data is numbers only?
What kind of graph do you create if you have categories and number data?
Line graph or scatter plot
Bar Graph
True or False: Heat can only be transferred by conduction in solids.
FALSE
Which of the following types of electromagnetic waves have the longest wavelength?
Radio waves
What does the term "albedo" refer to?
The ability of a surface to reflect light.
Cold air or hot air... which one has higher density?
Cold air, it sinks! Its heavy!
Where does the independent and dependent variables go on a graph?
Independent Variable is on the X Axis.
Dependent Variable is on the Y Axis.
Which of these is an example of heat transfer by convection?
a) A metal spoon heating up in hot soup
b) A warm breeze blowing through a window
c) The sun warming the Earth
d) A cold drink warming up in the sun
b) A warm breeze blowing through a window
Which electromagnetic wave has the highest frequency?
Gamma Rays
Why does snow have a high albedo?
Snow is very bright and reflects most sunlight.
Which has lower air pressure on Earth? Hot air or cold air?
hot air= rises up, less dense, less pressure on Earth.
Dependent variable= variable that is measured
Independent variable= variable that is changed
Which of the following best explains why you feel warm when standing near a campfire?
a) Conduction, because the heat travels through the air
b) Convection, because the heat rises from the fire
c) Radiation, because heat travels in the form of infrared waves
d) Conduction, because heat travels through the firewood
c) Radiation, because heat travels in the form of infrared waves
What type of electromagnetic radiation is used in night vision devices?
Infrared Waves
How does a surface with a low albedo affect the Earth's temperature?
It absorbs most of the sunlight, warming the Earth.
Which of the following statements is true about air pressure?
a) Air pressure is higher at sea level than at the top of a mountain.
b) Air pressure increases as you go higher in altitude.
c) Air pressure is the same everywhere on Earth.
d) Air pressure does not affect weather patterns.
a) Air pressure is higher at sea level than at the top of a mountain.
A researcher is testing how the amount of sunlight affects the growth of plants. The researcher measures the height of the plants after different amounts of sunlight exposure.
You are boiling water in a pot on a stove. Describe the role of conduction, convection, and radiation in this process.
What is the relationship between the wavelength and the frequency of electromagnetic waves?
The wavelength and frequency of electromagnetic waves are inversely related. As the wavelength increases, the frequency decreases, and vice versa. This means that waves with shorter wavelengths, like gamma rays, have higher frequencies, while waves with longer wavelengths, like radio waves, have lower frequencies.
You are studying a region where large areas of ice are melting rapidly. How might this affect the local climate?
As ice melts, the albedo of the region decreases because ice has a high albedo and reflects most sunlight. With less ice, darker surfaces like ocean or soil are exposed, which absorb more sunlight, causing the region to warm up faster and possibly accelerating further melting.
How do the tilt of the Earth’s axis and its orbit around the Sun influence the climate?
The Earth’s orbit around the Sun causes variations in the distance from the Sun, which also affects the intensity of sunlight and, consequently, the climate of a region.
You are conducting an experiment to see how the amount of sugar in a drink affects how sweet it tastes. You test drinks with 0g, 5g, 10g, and 15g of sugar and ask people to rate the sweetness on a scale from 1 to 10.
