Describe transform plate boundary
Plates remain unchanged, slide past each other
Explain how evaporites are formed. What is this process called?
Precipitation is the process that separates solids from a solution and forms evaporites
Wind and _____ moving over the surface break rock down into sand
Rain
Sedimentary rocks are made from sand and _____ compresses under heat and pressure
Water
How is sandstone deposited?
Water or air, can be represented by a number of different geologic environments
Sedimentary rocks are formed from _____ and _____ of igneous and metamorphic rocks
Weathering, Erosion
Explain how weathering and erosion aid in the formation of sedimentary rocks
Weathering- disintegration and decomposition of rock at the surface of Earth. Erosion- incorporation and transportation of material buy a mobile ager like water, wind, or ice
When softer rock erodes faster than the harder rock above, sometimes _____ is formed
Arch
____ in some rock were formed by chemical reactions in the rock when cool
Bubbles
When rain combines with iron in rock, it forms rust, which is a form of ______ erosion
Chemical
Composed of chemical material that was previously dissolved in water and later precipitated by inorganic processes
Chemical Sedimentary Rocks
Formed from process of water- dwelling organisms are biochemical sed rock
Chemical sed rock
_____ in the air contribute to erosion
Chemicals
Describe Oceanic-oceanic convergence and give example
Collision causes deep trenches because both subduct. Mariana Trench (Pacific) and Puerto Rican Trench
As water flows over rocks, it dissolves minerals causing different _____ to sometimes appear
Colors
Describe Oceanic-continental convergence and give example
Oceanic crust subducts and gets volcanoes on continent. Cascade Range (volcanoes)
Describe Continental-continental convergence
Fold upwards and create mountains. Rocky Mountains, Himalayans, Alps
Sedimentary rocks may contain _____ and indicate____
Fossils, Climates/ Environment
A huge flood happened in Washington State when a ____ broke
Glacier
Rocks ____ been melted or molten at some time
Have
What is the name and chemical compound of the indicator used to identify calcite?
Hydrochloric Acid (HCL)
Pounding water, wind, ____, and rain are major causes of erosion
Ice
Igneous rocks come from the word _____ meaning fire
Ignite
The process of converting sediments to solid rock by cementation or compaction
Lithification
____ rock is a combo of the other two and has changed into new rock
Metamorphic
More dense than continental crust, mainly made of iron
Oceanic Crust
Wind sometimes picks up ____ and blows them into rocks causing the rock to erode
Sand
Rock can change into sand and sand can then change into _____ over many years
Soil
Describe divergent plate boundary
The plates along the boundary are spreading and occur at mid-ocean ranges, results in construction
Describe convergent plate boundary
The plates collide
____ in farmland has a lot of living things in the top layer of horizon
Topsoil
What type of faults are likely to parallel the direction of transform plates? Give example
Transform faults, fault parallel to plate boundaries. Sanadras fault in cali
_____ can hold back soil from eroding and also break apart rocks causing erosion
Trees
