Weathering is processes that work to what?
What is break down rocks
100
Sediment is smaller loose pieces of rock called what?
What is sand silt and clay
100
How many types of rock are in the rock cycle?
What is 3- igneous, sedimentary and metamorphic
100
Erosion is the process of wearing away surface materials and doing what to it?
What is moving it somewhere else.
100
How is igneous rock formed?
What is from the cooling and hardening of magma
200
What are the two types of weathering?
What is chemical and mechanical
200
Soil can take how long to form?
What is thousands of years
200
What types of rocks can become magma? Through what process?
What is all of them through melting
200
Where is erosion more common? What kind of land?
What is steep slopes
200
How is sedimentary rock formed?
What is from the compaction and cementation of sediment
300
What is mechanical weathering?
What is physical process that breaks up rock into smaller pieces
300
What is soil?
What is a mixture of sediment, organic material, minerals, water and air.
300
what processes must a metamorphic rock go through to become an igneous rock?
What is melting and cooling
300
erosion occurs what water does what?
What is flows along earth's surface
300
How is metamorphic rock formed?
What is when minerals in existing rock are changed by heat and pressure
400
What is chemical weathering?
What is chemical reactions which dissolve minerals in the rocks breaking them down
400
Does soil differ based on location?
What is yes
400
all rocks can be weathered and become what?
What is sediments
400
Erosion also occurs when what picks up the sediments and transports them somewhere else? (not water)
What is wind
400
What is crystallization?
What is magma cooling at different speeds. The slower it cools, the bigger the crystals.
500
Give an example of mechanical weathering. Give an example of chemical weathering.
What is plant roots, animal burrowing or ice wedging. What is Carbonic Acid or Oxidation.
500
Due to weathering, different layers of soil form. These layers are known as what? These layers make up what?
What is horizons and soil profile.
500
If igneous rock goes under the process of heat and pressure, what does it become? Can it get back to igneous rock in one step?
What is metamorphic rock, and no.
500
When water seeps down through the soil horizons and dissolves, it carries minerals into lower horizons. This is known as what?
What is leaching
500
What is metamorphism?
What is when rock is exposed to extreme heat and pressure under earth's surface, but does no melt.
