Layers of the Earth Rock Cycle More on Rock Cycle Weathering More Geologic Processes
100
What is the mantle
This layer of Earth is made up of molten and solid rock.
100
What is cooled
Igneous rock is formed from lava once it is
100
What are sediments
The products of weatherig are called
100
What is chemical weathering
The Chemical change within the rock’s minerals breaking down the bonds holding the rocks together, causing them to fall apart into smaller pieces.
100
What is erosion
This process carries the rocks away
200
What is the inner core
This layer is at the center of Earth and is made up of solid iron and nickel
200
What is magma and lava
These two things are formed when metamorphic rocks melt
200
What is compaction and cementation
To form a sedimentary rock these processes must occur.
200
What is mechanical weathering
The process that breaks rocks apart without changing their chemical composition
200
what is gravity, water, wind, and ice
The four types of erosion
300
What is the lithosphere
This layer is made up of the crust and top part of the mantle. It is a rigid shell overlying the weaker interior
300
What is heat and pressure
This process changes sedimentary rocks into metamorphic
300
What is obsidian
This rock is an igneous rock, that forms from cooling magma, it is black and very shiny.
300
What is oxidation, carbonation, hydrolysis
Name one of the three types of chemical weathering
300
What is deposition
When sediments are carried away and form layers one on top of the other, this processes is called
400
What is the asthenosphere
This layer is the upper part of the mantle and where convection occurs
400
What is cooling and hardening
Magma and lava form an igneous rock throught this process.
400
What is granite
This type of rock is used in the countertops of our kitchens
400
What is abrasion, ice wedging, plant roots, burrowing, temperature change, and gravity
Name one of the 6 types of physical weathering
400
what are arches, sand dunes, mushroom rocks
Name some features created by wind erosion
500
Inner Core, Outer Core, Mantle, Asthenosphere, Lithosphere, Crust
List the layers of the earth from the most dense to the least dense--remember there are 6
500
What is weathering
Sedimentary rocks can turn into sediments by this process.
500
Do the rock cycle hand gestures
500
Mechanical: quick, more likely to happen,
Chemical: slow effecting, rare,
Same: both can occur at the same time,
Other than one is caused by chemicals and the other is physical-what are some other differences and similarities between chemical and mechanical weathering
500
What are landslides, stump/creep, mud flows
Name some features created by gravity erosion
