igneous
What starts the process of igneous rocks
What is cementation
When sediments crystalize or stick together
Where are metamorphic rocks formed
deep in the earth
What is foliated rock
When metamorphic rocks have layer like bands
What is physical weathering
When a force moves or break rocks such as wind,heat or rain Etc.
What is characteristic you can find on extrusive rocks
vesicles(air bubbles)
What is lithifacation
When sediments turn into sedimentary rocks
What is a parent rock
A metamorphic rock before it was exposed to heat and pressure
what does glassy mean
It looks shiny or scratchy
What happens when a rock cools
it tightens or gets smaller
What do you use to identify a igneous rocks
texture and color
what does it mean if a rock has a glassy structure
it means it has a scratchy or shiny apperance
What does medium grained mean
You can sometimes see the crystals
What are the four kinds of sizes for clastic rocks
Silt,sand,pebble/cobble,and clay
What happens when a rock gets really hot
It expands
How does the amount of silica effect the color of a rock
The more silica the lighter the color
What are the three characteristics used to describe sedimentary rocks
type, structure, and texture
What does a parent rock do for scientists
It allows us to make a connection between the two
What does an intermdiate color mean
gray or brown
when do animals cause weathering
When they burrow down
What are the four textures of igneous rocks
fragmental, glassy, coarse, and fine
what does it mean if it is a fine texture sedimentary rock
no visual sediments
How do we describe the texture of a metamorphic rock with big crystals
Coarse grained
How are crystalline and resinous rock different
Crystalline has crystal while resinous contains resin
What does felsic mean
very light color
