Rock Cycle
S A series of processes on the surface and inside the Earth that slowly changes rocks from one kind to another
S Example: sedimentary à heat & pressure à metamorphic à melting à magma à cooling à igneous à weathering à sediment à compaction & cementation à sedimentary
Rock Cycle
Sediment
S Small, solid pieces of material that comes from rocks (or sometimes organisms)
S Examples: sand, silt, gravel
S Non-examples: water, soil
Weathering
S The chemical and physical processes that break down rock on the Earth’s surface. Weathering is either mechanical (physical) or chemical.
S Examples: freezing & thawing, abrasion, plant growth, animal activity, water running, oxidation
S Non-examples: rock stays the same
Erosion
S The process by which natural forces move weathered rock and soil from one place to another.
S Examples: running water, mudslide, glaciers, waves, wind
S Non-examples: mining
Deposition
S The process by which sediment settles out of the wind or water carrying it.
S Examples: a glacier melts and rocks are dropped, ocean waves leave sand behind, wind creates sand dunes.
S Non-examples: weathering, erosion
Compaction
S The process that presses sediment together, one step in the formation of sedimentary rock.
S Examples: time + force; more sediment builds up on top and stuff on bottom is compacted
S Non-examples: erosion
Cementation
S The process in which dissolved minerals crystallize and glue particles of sediment together.
S Examples: sandstone, cobble, shale
S Non-examples: granite, obsidian, marble
