Rocks Test Corrections

Which of the following statements describes how rocks are classified? AKS 2b (DOK 1)

• Rocks are classified based on stratifications

• Rocks are classified based on how they are formed

• Rocks are classified based on where they are located

• Rocks are classified based on their color and hardness

Refer to the diagram above. What processes are occurring along arrows E and D to turn both the sedimentary rock and igneous rocks into metamorphic rocks? AKS 2b (DOK 1)

• Heat and Pressure

• Melting and Cooling

• Erosion and Depostion

• High temperatures and cementation

Which of the following best describes the differences between a metamorphic and igneous rock? AKS 2b (DOK 1)

• 
  A metamorphic rock is formed by weathering and erosion while an igneous rock is formed by magma or lava.

• A metamorphic rock is formed by magma or lava while an igneous rock is formed by weathering and erosion.

• A metamorphic rock is formed by heat and pressure while an igneous rock is formed by melting, cooling, and hardening.

• A metamorphic rock is formed by melting, cooling, and hardening. while an igneous rock is formed by heat and pressure.

When limestone is exposed to enough heat and pressure, it goes through physical changes.  

These changes can turn limestone into a different kind of rock called marble. Which of these best describes marble? AKS 2b (DOK 2)

• It is an igneous rock.

• It is a synthetic rock.

• It is a sedimentary rock.

• It is a metamorphic rock.

During a summer vacation in Hawaii, an island formed by volcanoes, Wayne found several rock samples to share with his Earth Science class. All of the crystals were large and the rocks had a coarse texture. Based on this information, which of the following statements is true about the rocks Wayne found?  AKS 2b (DOK 2)

• The rocks were foliated.

• The rocks were extrusive

• The rocks were intrusive

• The rocks were nonfoliated

How do active volcanoes located on islands create more land area on these islands? AKS 2b (DOK 2)

• Lava from volcanoes cools and hardens, forming more land

• Lava from volcanoes melts through old rocks, exposing more land.

• Heat from volcanoes causes the ocean to evaporate, exposing more land

• 1. Heat from volcanoes causes minerals in seawater to condense, forming more land.

How does magma become a sedimentary rock? AKS 2b (DOK 1)

• 1. magma, melting, igneous rock, erosion,  sedimentary rock

• 1. magma, cooling, sedimentary rock

• magma   melting metamorphic rock heat and pressure sedimentary rock

• magma, cooling, igneous rock, erosion, sedimentary rock

A science student wants to start her own rock collection.  She finds the following rocks in her backyard and records a description of each type of rock in the table below.

Using this student’s detailed descriptions, classify each type of rock, and explain which evidence best supports the given answer. AKS 2b (DOK 3)

• 1. Rock 1 is a sedimentary rock because small rock fragments underwent the processes of compaction and cementation.  Rock 2 is a metamorphic rock because it has a glassy texture and formed from cooled lava.  Rock 3 is an igneous rock because it is foliated and formed by extreme pressure.

• Rock 1 is a sedimentary rock because small rock fragments underwent the processes of compaction and cementation.  Rock 2 is an igneous rock because it has a glassy texture and formed from cooled lava.  Rock 3 is a metamorphic rock because it is foliated and formed by extreme pressure

• 1. Rock 1 is a metamorphic rock because it has many visible pieces of rock pressed together.  Rock 2 is an igneous rock because it does not have any crystals.  Rock 3 is a sedimentary rock because it has bands which are similar to layers.

• 1. Rock 1 is a metamorphic rock because it has many visible pieces of rock pressed together.  Rock 2 is a sedimentary rock because it does not have any crystals.  Rock 3 is an igneous rock because it has bands which are similar to layers.

Two students in Earth Science Class constructed a model explaining the transformation of rocks in the rock cycle. Both students presented their models to their class.

Which students' model best explains how rocks change through the rock cycle?

• Model A is more accurate because it shows multiple pathways of geological processes that can change rocks

• Model B is more accurate because it shows multiple pathways of geological processes that can change rocks

• Model A is less accurate because it shows multiple pathways of geological processes that can change rocks

• Model B is less accurate because it shows multiple pathways of geological processes that can change rocks
