Rock Cycle
A solid mass of minerals or mineral-like materials
What is a rock?
Igneous comes from the latin word ignis which means.....
What is fire?
The order of events necessary to create sedimentary rock: erosion, cementation, weathering, compaction, deposition
What is: weathering, erosion, deposition, compaction and cementation?
Describe or explain what metamorphic rock means
What is that an existing rock is transformed into a new rock?
This is the type of rock that is created when existing rocks are transformed by heat, pressure, and fluids
What is metamorphic rock?
The three major types of rock
What are: Igneous, Sedimentary, and Metamorphic?
Name and briefly describe the two basic ways that igneous rock are formed
What are intrusive, beneath the surface, and extrusive, at the surface?
Rock sediments are classified by size. These are the size descriptions of clastic sedimentary rocks
What are: pebble angular, pebble round, sand, silt, and clay?
Metamorphic changes occur between the mantle and a few km below the surface. Name and describe the two types of metamorphism
Igneous rock has three different classifications based on composition (what its made of). Granitic composition can be described in this way
What is light colored, called felsic, made of feldspar and silica?
This is a model of how the rock types form and then transform from one type to another
What is the rock cycle?
What are texture and composition?
The difference between chemical sedimentary rocks and clastic
This is the effect heat, pressure, fluids have on metamorphism
What is that the cause the rock to recrystallize and compact more, changing the rock?
Igneous rock has three different classifications based on composition (what its made of). Basaltic composition can be described in this way
This is the type of rock that is formed from cooled lava or magma
What is igneous rock?
These are two examples of corse-grained and fine-grained igneous rocks that we read about
What are granite (corse-grained) and rhyolite (fine-grained)?
What is that biochemical rocks are made of living organism broken down and turned into rock?
What are foliated and non-foliated?
Describe what happens during the cementation process of creating sedimentary rock
What is dissolved minerals are deposited in tiny spaces between sediments, binding them together?
This is the type of rock that is formed from weathering, erosion, deposition, and cementation
What is sedimentary rock?
Igneous rocks that are porphyritic in texture, like andesite, are described as....
What is a mixture of large and fine-grained crystals?
What are: strata, fossils, ripple marks, and mud cracks?
This is what the term parent rock means
What is that it is the rock that a metamorphic rock used to be. Ex. Gneiss parent rock is Schist or Granite
These are the two types of pressure that result in the creation of metamorphic rock
What are confining and direct pressure?
