I am the natural process of breaking down rocks.
Weathering
I am ripples in the sand. What caused me?
Wind
What evidence from this photo shows weathering, erosion and deposition occurred? Be specific.
The puddles.
What is the most nutrient filled horizon of soil called?
Topsoil
What is WED an acronym for?
Weathering, erosion, and deposition.
The movement of sediment or soil from one location to another by means of water, ice, wind or living things.
Erosion
I am a whole in Earth's surface. I was weathered by an agent/factor. What caused me?
Plant Growth
A longshore current could create what type of environment of deposition?
A barrier island or beach
What are the layers of soil called?
Horizons
What comes from the pollution created by humans?
Acid Precipitation or Acid Rain
When particles carried by water, ice, or wind are deposited (dropped) in another location
Deposition
I am soil being "washed" away on the ground. What caused me?
Rain and/or water.
What are the primary agents of deposition?
Water, wind, ice, and gravity.
How is soil formed?
Weathered rock and organic material
What specific process is this an example of?
Chemical Weathering (Oxidation)
Acidic waters pounding against a canyon wall and changing it's structure.
Chemical Weathering
I am a bunch of bones deposited in a hole, of eroded soil. What agent/factor could have cause me?
I did it!!! Animal Action
What does deposition do to the environment?
It forms landforms from the sediment that is relocated.
How does each soil layer differ based on it's position?
Each layer can be different in color, thickness, and composition
True or False. Living things can both cause and prevent Earth's changing surfaces.
True
Water freezing in the cracks of rocks and expanding.
Ice wedging
I am a tree ripped out of the ground. Based on evidence from this photo (look closely) what caused me?
Human Activity (Deforestation).
Geological processes, along with the help of the Colorado River, formed me over a very long time? What am I? Be specific.
The Grand Canyon
Why is humus important to soil formation?
Provides nutrients to the soil which makes it fertile
What environment of deposition to this represent?
Barrier Island
