Which of the following examples demonstrates heat transfer through radiation?

• Boiling water on a stove

• A hamburger cooking on a grill

• Sun heating up a pool

• A heater blowing air into a room

What is the correct order of the layers of the Earth from the center moving outward?

• inner mantle, outer mantle, crust, core

• inner mantle, outer mantle, core, crust

• inner crust, outer crust, mantle, core

• inner core, outer core, mantle, crust

Reyna wanted to find the density of a silver bracelet. She found that its mass was 24 grams and its volume was 2 cm3. Using the formula, D = M/V.  What was the density of the silver bracelet?

• 4 g/cm3

• 6 g/cm3

• 26 g/cm3

• 12 g/cm3

Gabriella, an experienced scuba diver, observes that temperatures decrease and pressure increases the deeper she dives into the Ocean. She reasons that the same must be true of the layers of the Earth. Is Marla correct in her thinking?  Why or why not?

• No, while temperatures increase, there is no change in pressure within Earth’s layers.

• No, temperatures decrease and pressure decreases with greater depth into the Earth’s layers.

• No, temperatures increase and pressure increases with greater depth into the Earth’s layers.

• No, temperature and pressure do not change within Earth’s layers.

Brody and Molly rolled a watermelon into the pool. The watermelon floated in the pool. What conclusion can they make?

• The volume of the watermelon was more than the volume of the pool water.

• The density of the watermelon was more than the density of the pool water.

• The density of the watermelon was less than the density of the pool water.

• The volume of the watermelon was less than the volume of the pool water.

Slate is a metamorphic rock that forms from shale, which is a sedimentary rock. Which of the following processes would be needed for shale to form into slate?

• melting and cooling

• weathering

• erosion and deposition

• heat and pressure

Passion watches birds at a bird feeder for one week and records the number of birds seen there each day.  Jaiden places three different types of food in separate bird feeders and records the number of birds seen at each feeder every day for a week.  Which student is conducting an experiment?

• Passion is conducting an experiment because she is recording data.

• Jaiden is conducting an experiment because his investigation has controlled variables.

• Passion is conducting an experiment because her investigation has controlled variables.

• Jaiden is conducting an experiment because he is recording data.

A group of students want to investigate erosion occurring naturally on a riverbank.  The students decide to take pictures of the riverbank each day over a period of 12 months, then record what changes they see in the photos.  What is the MOST significant limitation to this type of investigation?

• Qualitative data cannot be collected from photos.

• Variables, such as the weather, cannot be controlled.

• Variables, such as the weather, cannot be controlled.

• The exact amount of erosion cannot be measured.

Fabiola is modeling seismic waves using a slinky toy.  She wants to see if the size of the "seismic" waves increase when the slinky toy is moving at higher speeds.  What is the test variable (independent variable) in this experiment?

• The test variable (independent variable) is the size of the slinky.

• The test variable (independent variable) is the speed of the slinky.

• The test variable (independent variable) is the size of the wave.

• There is no test variable (independent variable) is this experiment.

A group of students is studying the effect of temperature on the density of air.  They obtained the following results from a controlled experiment, and conclude that air density is directly related to temperature. What statement BEST supports their conclusion?

• Higher temperatures had higher density values than lower temperatures.

• Lower temperatures had lower density values than higher temperatures.

• Higher temperatures did not cause any changes in density values.

• Lower temperatures had higher density values than higher temperatures.
