Layers of the Earth | Rock Cycle | More on Rock Cycle | Weathering | More Geologic Processes |
---|---|---|---|---|
What is the mantle
This layer of Earth is made up of molten and solid rock.
|
What is cooled
Igneous rock is formed from lava once it is
|
What are sediments
The products of weatherig are called
|
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.
|
What is erosion
This process carries the rocks away
|
What is the inner core
This layer is at the center of Earth and is made up of solid iron and nickel
|
What is magma and lava
These two things are formed when metamorphic rocks melt
|
What is compaction and cementation
To form a sedimentary rock these processes must occur.
|
What is mechanical weathering
The process that breaks rocks apart without changing their chemical composition
|
what is gravity, water, wind, and ice
The four types of erosion
|
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
|
What is heat and pressure
This process changes sedimentary rocks into metamorphic
|
What is obsidian
This rock is an igneous rock, that forms from cooling magma, it is black and very shiny.
|
What is oxidation, carbonation, hydrolysis
Name one of the three types of chemical weathering
|
What is deposition
When sediments are carried away and form layers one on top of the other, this processes is called
|
What is the asthenosphere
This layer is the upper part of the mantle and where convection occurs
|
What is cooling and hardening
Magma and lava form an igneous rock throught this process.
|
What is granite
This type of rock is used in the countertops of our kitchens
|
What is abrasion, ice wedging, plant roots, burrowing, temperature change, and gravity
Name one of the 6 types of physical weathering
|
what are arches, sand dunes, mushroom rocks
Name some features created by wind erosion
|
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
|
What is weathering
Sedimentary rocks can turn into sediments by this process.
|
Do the rock cycle hand gestures
|
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
|
What are landslides, stump/creep, mud flows
Name some features created by gravity erosion
