Metamorphic Rocks
Metamorphic rocks with a layered or banded look are called--
What is Foliated?
What are two types of sedimentary Rocks?
What is Inorganic-land driven and what is chemically formed sedimentary rocks?
Lava cools quickly at the surface
What is extrusive rock?
Rock cooled from a lava or magma will become
What is igneous?
occurs when magma, which is always extremely hot, touches cold rock
What is Contact metamorphism?
rocks are made from the shells (i.e. hard parts), of once-living organisms or plant remains
What is bioclastic?
magma cools slowly deep in the Earth
What is Intrusive Rock?
Which of the following processes to make sedimentary rock?
What is compaction
, cementation
, deposition
no mineral alignment
What is non-foliated?
A rock made when the evaporation of salty evaporite lakes or deep ocean deposits
what is sedimentary chemical rocks?
gas pockets; rocks cool and release gases
What is vesicular?
During the rock cycle, sediment is transported by natural forces from one place to another.
what is erosion?
Which agents are necessary in the formation of metamorphic rocks?
what is heat and pressure?
the preserved remains, impressions, or any other evidence of once-living organisms.
What is fossils?
Individual grains can be seen with the naked eye
What is intrusive texture?
How do igneous rocks form?
what is through cooling and hardening of magma or lava
metamorphism that occurs over broad areas of the crust.
What is regional Metamorphism?
Most rocks that form from fragmental rock particles are classified as
What is clastic sedimentary?
igneous rocks have
light color (except obsidian which is black)
lower density
composition rich in silicon (Si) and Aluminum (Al)
What is felsic?
What type of rock is quartzite?
What is regional metamorphic?
