Igneous Rocks
Metamorphic Rocks
Rock Cycle
Lesson Outline Questions
100
Forms when sediments, rock fragments, minerals, or organic materials are deposited, compacted, and cemented together.
What is a sedimentary rock?
100
Forms from magma and/or lava when it cools.
What is an igneous rock?
100
This forms from existing rocks from heat and pressure.
What is a metamorphic rock?
100
Indicates that each type of rock can be formed into another type of rock.
What is the rock cylce?
100
This cools quickly above Earth's surface.
What is lava?
200
Weathering and erosion, deposition, compaction, cementation.
What ways do sedimentary rocks form?
200
Has big crystals and formed beneath Earth's surface.
What is an intrusive igneous rock?
200
Magma comes in contact with existing rock and the thermal energy of the magma interacts with the rock forming a new metamorphic rock.
What is contact metamorphism?
200
The tectonic process that forces rocks up from beneath Earth's surface.
What is uplift?
200
These are the two characteristics that can help idetify igneous rocks.
What is texture and composition?
300
This rock is coarse-grained and has has jagged, angular sediments.
What is breccia?
300
Formed above Earth's surface and has smaller crystals.
What is an extrusive igneous rock?
300
These metamorphic rocks form distinct, parallel layers.
What is a foliated metamorphic rock?
300
Weathering and erosion, compaction, deposition, cementation
What are the processes in the rock cycle that happen on Earth's surface?
300
This forms when lava cools too quickly to grow crystals.
What is volcanic glass/obsidian?
400
This rock has smooth, round sediments.
What is conglomerate?
400
Lava that cools quickly forms this type of rock.
What is an extrusive igneous rock?
400
The rock that changes during metamorphism.
What is a parent rock?
400
Deposition, compaction, cementation, weathering and erosion, melting, cooling and crystallization, heat and pressure.
What are the natural forces included in the rock cycle?
400
Metamorphic rocks do what and form layers during their formation.
What is bending?
500
Formed from the remains of something that was once living.
What is a biochemical sedimentary rock?
500
The crystals that form slowly in cooled magma.
What are large mineral grains?
500
This rock is foliated and looks like granite.
What is gneiss?
500
The rock cycle changes this sedimentary rock into marble.
What is limestone?
500
Bending and folding of rocks s common during the formation of what?
What are mountains?
