Rock Cycle Flashcards
What is magma?
Magma is formed beneath the surface of the Earth and is hot melted liquid rock
What was the third step in the starburst lab?
it was to heat up the starbursts for 30 seconds, making it into an igneous rock.
What was the second part of the starburst lab?
Applying heat and pressure makes it metamorphic rock.
What was the first step in the starburst lab?
Pulling it apart and making it sediments
What process creates metamorphic rocks?
Heat and pressure from sedimentary rocks create metamorphic rock.
Where are metamorphic rocks formed?
They are formed in mountain ranges and deep in the earth
What process creates sedimentary rock?
They are formed by compaction and cementation.
Where are sedimentary rocks formed?
they are formed near water
What prosses creates igneous rocks
the cooling of magma
where are igneous rocks formed
they are formed on volcano surfaces or inside the crust
What are some of the sand materials
glass, shale, shells, volcanic minerals, and sand
What are the sand colors
orange, grey, violet, red, green, black, dark brown, pink, white, and tan
What are chemical weathering
it is when water causes chemical weathering water/oxygen combines with iron to cause rust
What are examples of mechanical weathering
freezing water, deep rocks in the earth under pressure, plants making cracks in cement, water weathering down rocks
What is mechanical weathering
it is the process that breaks rocks apart without changing their chemical composistion
What is always happening to rocks
they are always changing and being recycled
