The Rock Cycle
Weathering
100
A plate boundary type where active volcanoes are most likely to form.
What are convergent oceanic-continental boundaries?
100
An inorganic material with definite structure and composition.
What is a mineral?
100
Rocks that are produced when magma cools and hardens.
What are igneous rocks?
100
Two processes that create an igneous rock from another rock type.
What melting and cooling?
100
During this break down of rock, the rocks size and shape are the only things that change. The composition stays the same, it just gets smaller.
What is mechanical weathering?
200
After the eruption of the Soufriere Hills volcano, much of the landscape was converted to this.
What is wasteland?
200
A mineral is composed of these. They have a patterned arrangement of atoms and all minerals have a different arrangement.
What is a crystal?
200
These are two types of igneous rocks.
What are extrusive and intrusive?
200
This process carries soil and sediment from one place to another.
What is erosion?
200
During this breakdown of rock the chemical composition changes, or chemical processes are used to break down the rock.
What is chemical weathering?
300
A steep sided volcano that erupts violently, and is composed of alternating layers of lava and tephra.
What is a composite volcano?
300
When a mineral is called this, it can be mined, smelted, refined, and then sold for a profit.
What is an ore?
300
These rocks are formed deep inside the Earth over a long period of time. It takes great pressure and heat to squeeze these rocks into a new form.
What are metamorphic rocks.
300
A rock type that is formed by compaction and cementation.It is formed from broken down bits and pieces of other rocks.
What is sedimentary rock?
300
When a rock changes colors it is an example of a particular type of weathering.
What is chemical weathering?
400
When a mineral is cut and polished it is called by this name.
What is a gem?
400
These are the two types of metamorphic rock.
What foliated and non-foliated?
400
The process by which rocks are broken down into sediment.
What is weathering?
400
Icewedging is an example of this particular type of weathering.
What is mechanical weathering?
500
Minerals can have one of these two properties, but not both. One is when it breaks into sheets, and the other is when it breaks into chunks.
What is fracture or cleavage?
500
These are the three types of sedimentary rock.
What are chemical, detrital, and organic?
500
In order for the Earth to build up enough heat and pressure to create a metamorphic rock, this must happen.
What is subduction or plate movement?
500
In this type of mechanical weathering the rock is broken down by wind and sand particles.
What is abrasion?
