Igneous Rocks
This is the name of molten rock found below Earth's surface.
What is magma?
Sedimentary rocks form when this material is compacted and cemented.
What are sediments?
Metamorphic rocks form when exposed to intense ___________ and ____________.
What is heat and pressure?
The Rock Cycle shows how one type of rock can do this over time.
What is change into another type of rock.
The process that breaks rocks into smaller pieces by wind, water, ice, or gravity.
What is weathering?
Rocks that form from lava cooling on Earth's surface are called...
What is extrusive igneous rock?
The process that presses sediments together under their own weight and squeezes out extra water and air.
What is compaction?
Metamorphic rocks that show visible bands to stripes are described as this.
What is foliated?
What type of change forms sedimentary rocks - physical or chemical?
What is a physical change?
The Grand Canyon formed mostly because of this process moving sediments over millions of years.
What is erosion?
If an Igneous Rock cools very quickly, it will have this texture because crystals didn't have time to form.
What is glassy?
The process that glues sediments together with minerals.
What is cementation?
What do scientists call the original rock that changes into a metamorphic rock?
What is a parent rock?
The main energy source that drives the formation of sedimentary rocks comes from this.
What is the Sun?
Breaking rocks into smaller pieces by freezing and thawing water is this type of weathering.
What is frost wedging?
The slower magma cools, the crystals that form are this size. What type of texture?
What is large/coarse-grained?
Sedimentary rocks often contain these, which give clues about past life.
What are fossils?
Marble forms from this type of parent rock.
What is limestone?
The main energy source that drives the formation of metamorphic and igneous rocks comes from this.
What is Earth's interior?
Sediments deposited at the mouth of a river, forming new land, is an example of this process.
What is deposition?
Explain why igneous rocks are sometimes called the "starting point" of the rock cycle.
What is because they form directly from cooled magma or lava?
Explain the order of the process that sedimentary rocks go through to form.
What is weathering, erosion, deposition, compaction, and cementation?
During metamorphism, rocks are exposed to extreme heat and pressure, but they do not reach temperatures high enough to do this:
What is melt?
How does an Igneous Rock become a Sedimentary Rock? How does a Sedimentary Rock then become a Metamorphic Rock? How does a Metamorphic Rock then become an Igneous Rock again? Explain the whole process.
What is: Igneous rock undergoes weathering and erosion to break into sediments, which are compacted and cemented to form sedimentary rock; then heat and pressure transform the sedimentary rock into metamorphic rock; then the metamorphic rock melts into magma and then cools, it forms igneous rock again?
What is the sequence of processes that turns a rock into sand at a beach?
What is rocks are broken down by weathering, moved by erosion, and then dropped as sediments on a beach by deposition?
