100
Inorganic means
not alive
not made of carbon
100
The rock cycle takes place over (100s / 1,000s / millions) of years
MILLIONS!!!!!
100
Difference between weathering & erosion
Weathering = breaking down
Erosion = transport
100
True or False: Weathering shapes the land.
True
100
Name 1 feature ON LAND created from erosion
Cave
Arch
Stack
100
"Litho" sand means sand from
rock
200
Do minerals make up rocks? Or do rocks make up minerals?
Minerals make up rocks
200
What does the rock cycle show?
How rocks change over time
200
Mechanical vs. chemical weathering
Mechanical = physical change (size, shape)
Chemical = changes chemical makeup
200
Name 1 feature ON LAND created from erosion
Valley
Canyon
200
Name 2 things sand/sediment can be made of
Shells
Bones
Rock
Plastic / manmade materials
Space material
Chemicals from water
200
True or False: Erosion happens before weathering
True
300
When gravity moves rocks downhill, it causes
Erosion
300
Name 2 processes in the rock cycle
Melting
Heating
Pressure
Compression
Sedimentation
Cooling
Crystallizing
Erosion
Weathering
300
Give example of mechanical and chemical weathering
Mechanical = abrasion (sand/rock/wind/water), plant growth, animals, ice wedging, pressure release
Chemical = water, oxygen, acids, wildlife (acids)
300
Name 2 ways weathering & erosion shape the land
Moving water
Moving glaciers
Gravity
300
Rock that dissolves easily in water is called
Permeable
300
True or False: Rusting and water dissolving rock are examples of mechanical weathering
False
400
___________________ gives minerals their symmetrical, repeating patterns
Crystal shape
400
Sedimentary rock would become igneous rock by....?
Sedimentary rock melting into magma then cooling
400
2 factors that affect how quickly a rock weathers - be specific!
Climate = wet/warm
Rock type = permeable
400
How do glaciers shape the landscape?
Glaciers move, scraping rock and moving that rock with it
400
Name 3 things that cause erosion
Water
Ice
Gravity
Glaciers
Wildlife
400
What would cause erosion of soil and rock down a hill?
Gravity
500
Name THREE characteristics of minerals
Natural
Inorganic
Solids
Crystal shape
Definite chemical composition
500
Give an example of the rock cycle using all 3 rock types AND their processes (how they changed into each other)
Igneous = cooled magma
Sedimentary = sediment under pressure
Metamorphic = heat/pressure
500
Name 4 examples of mechanical weathering
Abrasion
Plant growth
Animals
Ice wedging
Release of pressure
500
What landform is this and how is it shaped?
Valley / glaciers and rivers
500
Difference between sediment and sedimentary rock
Sediment = loose pieces of rock
Sedimentary rock = sediment under pressure
500
Moss and lichens break down rock with
weak acids
