Rocks
Physical Weathering
Chemical Weathering
Erosion
100
the study of our planet Earth;how it is made, what it is made of, and how it has changed over time.
Geology
100
layers if sediments (Fragments of rocks, minerals, animal or plant materials) form this rock
Sedimentary
100
Water gets into rock's cracks, freezes, expands, and breaks off pieces of rock
Frost Wedging
100
When oxygen change the color of the rock into a rust/orange color
Oxidation
100
wind causes smaller sediments to move in the direction of the blowing wind
Wind erosion
200
Scientist who studies the Earth; how it is made, what it is made of, and how it has changed over time.
Geologist
200
What do you look for when identifying sedimentary rocks?
Fossil imprints
200
Blown air and rushing water hits rocks and begin to crumble over time
Abrasion
200
Water causes the rock to dissolve (disappear)
Dissolution
200
rainfall, waves, rivers, and floods carry the sediments downstream
Water Erosion
300
How are mountains and valleys formed?
Two continental plates of the Earth's crust are pushed together.
300
When melted lava from a volcano is cooled and harden form this rock
Igneous
300
Rocks peel into sheets
Exfoliation
300
rocks change into other materials
Chemical Weathering
300
Giant slabs of ice that move slowly over land carving landforms bringing sediments with them as they move.
Glacier Erosion
400
Process where rock is dissolved, worn away, or broken into smaller pieces.
Weathering
400
What do you look for when identifing igneous rocks?
Shiny and Glasslike
400
Plant roots breaks up rocks as they grow larger
Plant action
400
Does weathering happen quickly?
No
400
Pulls rocks down the side of a mountain and cliff
Gravity Erosion
500
Rocks and sediments are moved from one place to another
Erosion
500
Sedimentary or igneous rocks change from heat and pressure for this rock
Metamorphic
500
physically breaks up the rocks
Physical weathering
500
List all the weathering and erosion types that helped bring down the Old Man of the Mountain
Frost-Wedging/Abrasion with wind as well as rain/ Exfoliation-the nose fell off in a sheet/Plant action/ Dissolution- water caused the rock to smooth and pieces to disappear/Wind erosion-high up in mountain very windy/Water Erosion from rainfall/Glacier erosion is what originally made the old man/Gravity erosion brought it down off the cliff/deposition occurred at bottom of the mountain
500
Process by which rocks, sand, and sediments are left in a new place by the forces of weathering and erosion.
