Rocky Questions
What is a principal ingredient in all rock types.
minerals
Igneous rock that formed from magma and cooled very slowly developing a coarse texture and large crystals.
intrusive
The process of red clay formation involves breaking down of sediment and what other process?
oxidation via H2O
Metamorphic rocks are created by these two primary forces.
heat and pressure
This type of topography is the official names for cave-like terrain.
Karst
This erosive force creates a U-shaped valley.
Glacier
This intrusive igneous rock cools slowly, has larger crystals and is commonly used in countertops.
granite
The process that squeezes out fluids and decreases the space between the grains in a sediment deposit and glues them together
compaction and cementation
These types of rocks can become metamorphic rocks.
igneous, sedimentary, metamorphic rocks
Which term explains how quickly water can pass through rocks or sediment? porosity or permeability
permeability
Before a rock becomes classified as sedimentary, these forces must occur.
weathering, erosion, transportation, depostion, compaction, cementation
What are the two classifications of igneous rocks based on light and dark mineral content?
mafic and felsic
The principal sedimentary rock that forms stalactites and stalagmites.
limestone
What are the two types of metamorphism we talked about in class?
contact and regional metamorphism
