Minerals, Rocks, Weathering, Erosion, & Deposition Quiz

In the processes responsible for changing sediments into sedimentary rock are compaction and

• intrusion

• cementation

• stratification

• foliation

Which of the following properties of minerals is usually tested on an unglazed porcelain plate?

• streak

• hardness

• fracture

• cleavage

Which statement about the formation of a rock is best supported by the rock cycle?

• Sediment must be compacted and cemented before it can change to sedimentary rock.

• Igneous rock must be melted and cooled before it can change to sedimentary rock.

• Sedimentary rock must condense before it can change to metamorphic rock.

• Sedimentary rock must cool before it can change to metamorphic rock.

Which of the following best describes the mineral composition of the rock?

• The layers show that the rock was formed by one or more minerals that cooled very quickly.

• The layers show that the rock was formed by a single element under high pressure.

• The layers show that the rock was formed by a single element under extreme heat.

• The layers show that the rock was formed by one or more minerals that compacted over time.

Josh noticed several cracks in the sidewalk. Weeds were growing through them, causing the cracks to expand. What process is this?

• erosion

• sedimentation

• deposition

• weathering

Which is the correct definition of a mineral's streak?

• a line of ore in the mineral that is a different color

• a crystal in the mineral that is a different color

• the color of the powder a mineral makes

• the color of the outside of the mineral

The diagram models a rock before and after undergoing some process. Which process is most likely modeled by the diagram?

• Water weathering the rock, settling in the crack and freezing, then breaking the rock as it expands.

• Winds weathering the rock, moving through the crack and causing the rock to break apart.

• Gravity eroding the rock, pulling down on its particles and causing it to break apart.

• Water eroding the rock, breaking down and carrying away loose rock particles.

Which would most likely increase erosion caused by a stream?

• increased rainfall

• decreased animal life

• increased evaporation

• decreased temperature

During a field trip to a Kansas state park, Uriah observes a rock in the shape of a mushroom, as shown. What is the most likely reason for the shape of the rock?

• animals eroding the rock

• wind weathering the rock

• acid rain dissolving the hard parts of the rock

• growth of small plants in the cracks of the rock

The diagram shows debris left in the path of a glacier. Which most likely describes the event in the diagram?

• It is an example of erosion by wind.

• It is an example of erosion by ice.

• It is an example of physical weathering by water.

• It is an example of physical weathering by gravity.
