Lessons on the Rock Cycle with Mr. Bradley

Which statement best describes the relationship between igneous and metamorphic rocks?

• Igneous rocks must go through the sedimentary process to change into metamorphic rocks.

• Igneous rocks are chemically changed into metamorphic rocks because of high temperature and pressure.

• Metamorphic rocks are formed from melting igneous rocks.

• Metamorphic rocks and igneous rocks do not follow a rock cycle.

Mr. Rieser challenges his seventh grade class to explain how the process of weathering, erosion and deposition are essential to the rock cycle. Each group's response is shown above. Which group has the best response?

• Group 1

• Group 2

• Group 3

• Group 4

Jasmine created the following flow chart about sedimentary rock. Flow Chart Where did Jasmine make a mistake?

• Weathering of rock material must occur after erosion takes place.

• Deposition must occur before sediment is cemented.

• Compaction must occur before sediment is deposited and cemented together.

• Erosion of weathered sediment must occur after compaction.

Which of the following statements best describes the relationship among tectonic plate motion, the rock cycle and subsurface geologic events?

• At divergent plate boundaries, hot magma rises to the surface as plates push apart forming mid-ocean ridges made up of igneous rock.

• At divergent plate boundaries, two plates merge and hot magma rises to the surface creating new igneous crust.

• At convergent plate boundaries, lithospheric plates move away from each other producing volcanic activity with magma eruptions made up of igneous rock.

• At convergent plate boundaries, sedimentary rock sinks into the Earth's outer core and the intense pressure reorganizes matter resulting in large igneous rock.

Which of the following statements best describes how metamorphic rock is formed?

• High temperature and intense pressure may transform an igneous rock into a metamorphic rock with banded layers.

• Low temperature and intense pressure may transform a sedimentary rock into a metamorphic rock with banded layers.

• High temperature and low pressure from Earth's core may transform an igneous rock into a metamorphic rock with banded layers.

• Low temperature and low pressure may transform an igneous rock into a metamorphic rock with banded layers.

Which of the following processes is most responsible for producing the landscape of Florida's beaches?

• convection, cementation

• plate movement, subduction

• erosion, weathering

• deposition, compaction

When rocks are crushed for use in industry the volume of crushed rock is generally less than the original rock. The manager of the Everglades Rock Crushing Company starts crushing rock from two identical rock containers. He notices that the volume of the crushed rock from the first rock container is different than the crushed rock in the second rock container. What kind of investigation is the manager conducting?

• The manager conducted an experiment because he collected and recorded specific data.

• The manager conducted an experiment where he manipulated the variables to yield different volumes in each container.

• The manager conducted an observational study where he manipulated the variables to yield different volumes in each container.

• The manager conducted an observational study which would require additional research to verify results.

Which of the following situations best describes the chemical weathering process of sedimentary rock?

• Sedimentary sandstone is carried away by water along the bedrock of a stream.

• Sedimentary sandstone allows water to freeze and thaw inside its cracks.

• Sedimentary limestone cliffs are battered by strong ocean waves.

• Sedimentary limestone is exposed to acid rain at the top of a mountain.

Scientists use a special computer that generates models of complex Earth systems interactions. Which of the following statements is least likely to describe how information from an Earth Systems computer model might be used?

• Information may be used to visualize a concept and transfer information to other disciplines within the earth sciences.

• Information may be used to design experiments and to formulate hypotheses in the earth sciences.

• Information can be used to encourage systems thinking within the earth sciences.

• Information can be used to reject other existing computer models within the earth sciences without further testing.
