Breaking it Down
What does W.E.D stand for?
Weathering, Erosion, Deposition
The two key processes that turn layers of sediment into solid rock.
Compaction & Cementation
A natural resource that can be replaced quickly by nature.
Renewable resource
What type of erosion carves out U shaped valleys?
Glacial Erosion
A canyon at Palo Duro Canyon State Park was formed by this force
A river
What does Weathering do? Give an Example.
Breaks it down.
Ex:A river carving a canyon over millions of years.
Why does sedimentary rock often have visible layers?
Sediment builds up over time In layers
This fossil fuel is formed from the remains of ancient plats and is used as a major energy source.
Coal
A river slowly carves this landform over time by cutting into rock.
A canyon
A rock sample contains fossils of ancient sea creatures, but it was found on a mountaintop. What does this suggest about Earths past?
That it was probably once covered by an ocean and later uplifted.
When sediment is dropped and comes to rest in a new location.
Deposition
This fossil fuel is formed from the remains of ancient marine organisms buried under layers of sediment.
Oil
These two fossil fuels are similar because they both form from tiny marine organisms over millions of years.
Oil & Natural Gas
This landform is created when a river deposits sediment and the mouth where it meets an ocean.
Delta
A student claims that sand dues are only formed by deposition .What argument could you use to challenge their claim?
You also need erosion and weathering to breakdown the rock into small sediments (weathering) and move it somewhere else (erosion)
The process where rocks are word down by wind-driven particles over log periods.
Abrasion
Evidence of past life that gets trapped within layers of sedimentary rock.
Fossils
Explain why fossil fuels are considered nonrenewable resources.
They take millions of years to form and are used up faster than they are replaced.
Two type of forces that shape the Earth surface.One builds up landforms, while the other wears them down.
Constructive and destructive forces
A riverbed contains small,rounded rocks instead of jagged ones. What does that day about how the rocks were shaped.
The rocks have been weathered and smoothed by water over time.
Explain how deposition plays a role in forming a delta at the mouth of a river.
A river slows down, it drops sediment, which builds up over time to form a delta
The deeper a fossil is found in layers of rock, the _____it is.
Older
Describe how fossil fuels and fossils are similar in how they are formed.
Both are formed from the remains of once-living organisms, but fossil fuels require millions of years and immense pressure to develop.
Explain how a river can both erode rock and create new landforms.
It carves canyons by eroding rock and forms deltas by depositing sediment.
A student argues that erosion only happens through water . What evidence could you provide to prove that erosion occurs in multiple ways.
Erosion also happens through wind, ice, and gravity.
