The Rock Cycle
True or False: The rock cycle has a very direct path that rocks follow
False
This type of rock is formed by magma or lava cooling
Igneous rock
What two processes form rocks?
Temperature and Pressure
The series of processes in which rock forms, changes from one type to another, is broken down or melted, and forms again by geologic processes...
Rock Cycle
What do all three rock types erode into?
Sediment
What type of rock forms when an existing rock has been exposed to high levels of heat and pressure?
Metamorphic Rock
This is the process of wind, water, ice, and temperature changes breaking down a rock into sediment
Weathering
The process by which wind, water, ice, or gravity transports soil and sediment from one location to another...
Erosion
What is the process called where sediment is turned into sedimentary rock?
Compaction or Concretion or Pressing (accept any)
If an igneous is described as an EXTRUSIVE rock, where did it form?
On Earth's surface
Does pressure go up or down as you go down into the Earth? Bonus points for why
Pressure goes up because there is more rock above you pushing down on you
What is one of the three parts of the rock definition? Bonus points if you can name multiple
1. Solid
2. Naturally Occurring
3. Mixture of Minerals
What is one of the two main ways that sedimentary rocks form? Bonus points for both
1. Sediment is cemented together by pressure
2. Minerals dissolved in water cement together
If an igneous rock is described as INTRUSIVE, what does that mean in terms of crystal size?
Intrusive rocks have larger crystals
What is the difference between erosion and deposition?
Erosion is the transport of sediment; Deposition is the putting down of sediment
An area of deep cracks that forms between two tectonic plates that are pulling away from each other...
Rift Zone
