What is the correct order of the layers of the Earth from the center moving outward?
crust, mantle, outer core, inner core
crust, mantle, inner core, outer core
inner core, outer core, mantle, crust
outer core, inner core, mantle, crust
Marla, 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, temperatures increase and pressure increases with greater depth into the Earth’s layers.
No, temperatures decrease and pressure decreases with greater depth into the Earth’s layers.
Yes, temperatures decrease and pressure increases as you move through the Earth
No, while temperatures increase, there is no change in pressure within Earth’s layers.
Earth is composed of many metallic elements. Which layer of Earth contains the greatest amounts of dense, solid iron and nickel?
outer core

The mantle is part of Earth’s interior. Where in Earth’s interior is the mantle located?
between the outer core and the inner core
just below the inner core
between the lithosphere and the outer core

mantle
crust
inner core
outer core

volume and weight
mass and weight
mass and volume
size and shape
Dustin knew that he could find how much space the box took up. If he wants to find the density, what other tool does Dustin need to use?
a ruler to find it's volume
a graduated cylinder to find it's volume
a triple beam balance to find it's mass
a ruler to find it's mass
Which of the following is the best explanation for why water and oil separate when poured in a glass?
they have different colors
they have different densities
they have different volume
they liquids are two different states of matter
Ms. Anderson had a basketball and a bowling ball that were similar in size (have similar volumes). However, the bowling ball has more mass than the basketball. What can you conclude from this information?
A basketball contains more matter than a pumpkin
A basketball has the same properties as a bowling ball.
A bowling ball contains a smaller amount of mass per volume than a basketball.
A bowling ball has a greater density than a basketball.
Assume that you have 100 mL of each liquid. Which liquid would have the smallest mass in this volume?
corn syrup
rubbing alcohol
water
gasoline
Jessica noticed when she is standing around the fire roasting marshmallows, she can feel the heat from the fire. What type of heat transfer is this?
radiation
convection
conduction
insulation
How many independent variables (what you change) can you have in an experiment?
1
2
3
4
True or False: You should only test your variable one time to conclude if your hypothesis is correct.
True
False
A volcano is a complex and dangerous system. A scientist wants to study how the forces generated by an erupting volcano affect how far soot and ash are thrown from the volcano, without studying the system directly. What method should the scientist use to conduct the research?
Make casual observations of dormant volcanoes and the rocks surrounding them.
Construct a model of a volcano and use it to conduct an experiment.
Conduct systematic observations of an extinct volcano and the rocks in the area.
Use a telescope to observe the activity of an erupting volcano from a distance over time.
Which of the following is an example of heat transfer through radiation in Earth's Systems?
Heat rising through vents in the ocean floor
Beach sand getting warmed by the sun
Warm air replacing cooler air
Hot gases given off during a volcanic eruption
Anthony and Madison are making a poster to show how heat can be transferred by conduction. Which of the following is the best example of conduction for their poster?
A shirt warmed when it touches a hot iron
Sunlight warming a room early in the morning
Warm and cold water circulating in the ocean
Hot air rising and cold air sinking on a beach
"Lava lamps" contain colored liquids. These liquids form globs that rise to the top due to
radiation
convection
conduction
insulation
Michael and Isabella are working together on an assignment. They must find an example of heat transfer by convection from some illustrations. Which illustration will best represent convection?
Warm air over the beach rises while cooler, dense air from the ocean rushes in
A house burns down. The vinyl siding of the house next door warps
A chair is several feet from a fireplace. The side of the chair facing the fireplace gets warm
Hot coffee is stirred with a spoon; the spoon gets hot
Why is it important that science experiments can be repeated by other scientists?
It is not reliable unless you test different variables
It is not reliable unless others can repeat the experiment and get similar results
it is not reliable unless more than one dependent variable is measured against others
It is not reliable unless the procedure is changed to be tested again.
