How do you form a Metamorphic rock?
What is when a rock is changed by heat or pressure, or by chemical reactions.
100
How do you form an Igneous rock?
What is from the cooling of magma or lava
100
What are the three major groups of sedimentary rocks?
What is clastic rocks, organic rocks, and chemical rocks
100
What is erosion?
What is the process by which water, ice, wind, or gravity moves weathered particles of rock and soil
100
what is a sediment?
What is small, solid pieces of material that come from rocks or living things
200
What subclass of metamorphic rock is this?
Foliated.
200
What is the difference between the lava coming out of a SHIELD volcano and the lava coming out of a CINDER CONE volcano?
Shield volcano has lava that is much thinner/runnier than the cinder cone.
200
How is a Sedimentary rock formed?
What is through a sequence of process. weathering, erosion, dessposition, compaction, and cementation.
200
What is deposition?
What is the process in which sediment is laid down in new locations
200
when do chemical rocks form?
What is they form when minerals dissolve in water solution chrysallize.
300
What subclass of Metamorphic rock is this?
Nonfoliated.
300
You notice that an Igneous rock is completely lacking crystals. Why does it not have any crystals?
It cooled too quickly for crystals to form/grow.
300
how does a igneous rock become a sedimentary rock?
What is through weathering and erosion
300
What is compaction?
What is the process that presses sediments together.
300
Water, wind, and even glaciers can carry sediment away from its parent rock in a process called...
Erosion
400
If these both form from the same process, why does one have foliation and the other doesn't?
Foliation requires heat & pressure applied to more than one mineral.
Non-foliation occurs when only one mineral is present (sometimes 2 if they are very similar).
400
granite is an (instrusive/extrusive) igneous rock
What is instrusive
400
what does sandstone form from?
What is the sand on the beaches, the ocean floor, riverbeds, and sand dunes.
400
What is cementation?
What is the process by which dissolved minerals chrystallize and glue particles of sediment together into one mass
400
what can turn igneous rocks into sediments?
What is weathering
