Ch3 Flashcards
Result from a forcing pressure on an area
Pressure
When earthquakes occur they produce
Seismic waves
The layer of rock that forms earth outer skin
Crust
A dark fine grained rock
Basalt
A rock usually is a light color and has coarse grains
Granite
The rock below the boundary is the solid material of the ——– a layer of hot rock
Mantle
The group that contains the crust and upper most mantle this is called
Lithosphere
Below the lithosphere this soft layer is called
Asthenosphere
The result of increasingly high pressure
Mesosphere
A layer of molten metal surrounding the inner core
Outer core
A dense ball of solid metal
Inner core
The transfer of energy that is carried in rays is called
Radiation
Heat transfer by a movement of fluids is called
Convection
Heat transfer between material that are touching is called
Conduction
The measure of how much mass is in an object
Density
The flow that transfers heat within a fluid is called
Convection current
The approximately 20 minerals that make up most of the rocks of earths crust
Rock forming materials
most rocks are made up of these particles
Grain
The look and feel of a rocks surface
Texture
Forms from cooling of molten materials
Igneous rock
Forms when small particles of rocks or the remains of plants or animals are pressed and demented together
Sedimentary
Forms when a rock is changed by heat or pressure or by chemical reactions
Metamorphic
Solid naturally occurring substances
Minerals
Igneous rock formed from lava that erupted onto earths surface
Extrusive rock
Igneous rock that formed when magma hardened beneath the surface of earth
Intrusive rock
The thin flat layering found in most metamorphic rocks
Foliated
Small solid peices of material that come from rocks or living thinks
Sediment
The effects of freezing thawing plant roots acid and other forces on rock
Weathering
The process by which running water wind or ice carry away bits if broken up rock
Erosion
The process by which sediment settles out of the water or wind carrying it
Deposition
The process that presses sediment together
Compaction
The process in which dissolved minerals crystallize and glue particles of sediment together
Cementation
A sedimentary rock formed when rock fragments are squeezed together
Clastic rock
Forms where the remains of plants and animals are deposited in layers
Organic rock
Forms when minerals dissolved In a water solution crystallize
Chemical rock
A series of processes that occur on earths surface and in the crust and mantle that slowly change rocks from one kind to another
Rock cycle
Where does the heat come from that drives this convection current in the mantle
The core and the mantle
In order list the sequence or processes through which sedimentary rocks forms
Weathering and erosion
Deposition
Compaction
Cementation
What is ways sedimentary rocks have been used throughout history
Tools and building materials
Which type of rock
Coal
Organic
Describe how the granite of a mountain could change first into sandstone and them into quatize
The particles breaks off then streams carry them to the ocean layers of sand slowly pile on the ocean floor and is then compacted
Describe how collision between continental plates can result In metamorphic rock
When the plates collide heat and pressure slowly change from one type of rock to another
