Types
This type of rock forms when lava or magma cools and hardens
Igneous
The process that breaks down rocks into smaller pieces.
Weathering
What do you look for in an igneous rock
Crystals or Luster (shiny)
The process that continuously changes rocks from one type to another.
Rock Cycle
Any rock can change into another through this
Rock cycle
Formed by layers of sediment being compacted and cemented together.
Sedimentary
How can Ice or water break a rock
This happens when water freezes and expands in rock cracks.
What is sediment
small pieces of other rocks
How do you make Metamorphic
Heat and Pressure
The final stage in the erosion process.
deposition
This type of rock forms when other rocks are changed by heat and pressure.
Metamorphic
What is the force is the most common that breaks rocks
Water
Beaches are formed when waves deposit this.
Sand
how do you make sedimentary rocks
Sediment and pressure
When gravity pulls rocks and soil down a slope.
Landslides
Obsidian is which type of rock
Igneous
The process that moves rock particles from one place to another.
Erosion
Breaks into smaller pieces and mixed with other material and hardens
How do you make Igneous rocks
Heat
Moving ice that erodes rocks is called this.
Glaciers
Sedimentary
The process where sediments are dropped or settle out of water or wind.
Depositition
What is the difference between Lava and Magma
Lava - what comes out of the volcano
magma - what it is called when still in or below earths crust
The process of melting and cooling happens mostly here.
in or beneath earths crust
Wind erosion is most active in this type of region.
the desert
