Sheila is classifying the rocks in her collection. She knows that limestone often contains fossils. In which category of rock should she classify these rocks?
igneous
granite
metamorphic
sedimentary
Which process would form an igneous rock?
Melted rock cools and then hardens.
Small pieces of rock get squeezed together.
Animal remains are covered by rock that hardens around it.
Heat or pressure changes an existing piece of rock into a new rock.
Which of the following best explains how layers can become sedimentary rock over many years?
Sand in the sediment melts and turns into rock.
Changing water temperatures turn sand in the sediment into rock.
The pressure of the water compacts the sediment into rock.
Pollution caused by humans turns the sediment into rock.
Which of the following describes how a metamorphic rock forms?
formed from magma that cooled slowly
formed by pressure and heat over time
formed from lava that cooled quickly
formed by pieces of rock cemented together
Molten rock is called magma. As it cools, magma turns into solid rock on the surface. What type of rock does magma form as it cools?
igneous
sedimentary
metamorphic
fossil
Look at the descriptions below. Which rock is a metamorphic rock?
shale - formed from layers of sediment pressed together
marble - formed by pressure and heat
pumice - melted rock that has cooled
shale
marble
pumice
none
While learning about rocks and minerals, students were observing a rock their teacher gave them. Students recorded their observations in their notebooks.
Student 1: The rock probably came from a volcano.
Student 2: The rock looks awesome.
Student 3: The rock had a mass of 25 grams.
Student 4: This rock is the class's favorite rock.
Based on the information above, which student recorded data in their notebook?
Student 1
Student 2
Student 3
Student 4
While observing minerals, students performed a hardness test on four types of minerals. Based on the evidence in the chart, what conclusion can students form?
Quartz is the hardest mineral students tested.
Calcite is the softest mineral students tested.
Talc is harder than quartz.
Corundum is the hardest mineral students tested.
Mia is trying to identify the mineral shown. She records the following property of the mineral in her notebook.
The mineral can break easily into flat sections.
Which property of the mineral did Mia record in her notebook?
luster
streak
hardness
cleavage
Daunte performs several tests on a mineral to identify it. Which property of the mineral will Daunte be able to identify using this test?
attraction to magnets
streak color
hardness
cleavage
Sonia took a flashlight and shined it on several minutes. She was testing the reflection of light off of each mineral. What property of minerals was Sonia testing?
luster
streak color
cleavage
hardness
Quinn grouped minerals she found on the playground during recess. What property did she most likely use to sort the minerals?
luster
cleavage
hardness
color
Which of these correctly explains the relationship between rocks and minerals?
Rocks are materials found on Earth's surface, and minerals are found only underground.
Minerals are the basic building blocks from which nearly all rocks are made.
Minerals are large structures that can be broken down into smaller pieces, called rocks.
When rocks are heated to very high temperatures, they are changed into minerals.
Janelle is identifying the properties of a mineral that she found in her backyard. Based on the tools that Janelle has gathered, what property is she identifying?
hardness
luster
cleavage
streak color
Kyler wanted to investigate if there is a relationship between a mineral's hardness and its mass.
Question: Do minerals that are higher on the Mohs Hardness Scale have more mass than minerals that are lower on the scale?
Hypothesis: The harder the mineral is, the heavier it will be.
Based on the information above, what is Kyler's next step?
Share his results with other scientists.
Analyze the data he has collected and draw a conclusion.
Conduct the investigation and collect data.
Repeat the investigation to make sure his results are valid.
While investigating minerals, Kyler found a new mineral that he thinks might be lighter and stronger than any other mineral currently known. What does Kyler need to do in order for his accidental find to be a valid scientific discovery?
Kyler needs to tell a real scientist what he found.
Kyler needs to take the mineral to a science lab to make it a valid scientific discovery.
The discovery cannot be valid because Kyler did not use all steps of the scientific method to discover the new mineral.
Kyler needs to make observations and conduct an experiment to learn more about the new mineral.
