Weathering
What is weathering?
The breakdown of rock
Islands are an example of what process?
Deposition
How would over grazing affect the soil?
It would make the soil loose and vulnerable to erosion
What is the order of the 3 types of soil from smallest to largest?
Clay, silt, sand
In a nearby mountain water runoff the mountains side DISSOLVING limestone, what process is this?
Chemical wheathering
What would happen to young mountains with sharp peaks and edges over time?
It would erode the sharp peaks over time resulting in a smoother mounatin
What is the order of erosion, wheathering, and deposition?
Weathering, erosion, deposition
What human activity is similar to wheathering?
Mining
Explain the differences of how water interacts with sand and clay
Water will flow through the sand grains easily, while water will be stuck on top of the clay particles or slowly move through it
What is an example of chemical weathering performed by plants?
Lichen releasing weak acids in order to break down rock
Landslides are caused by what?
Gravity pulling the rocks down to the Earth
What is oxidation?
The process of rock interacting with oxygen to form rust and break down
How can humans prevent or lessen the chance of erosion on Earth?
Allow natural vegetation to grow or by planting more native plant life
What is humus?
Decayed organic matter
What is the process when small bits of sediment are carried by wind or water to crash against larger pieces of rock to break them down over time?
Abrasion
Explain in two ways the soil from the coastline could be eroded
Strong winds or waves from a nearby storm
Explain ice wedging
The process of water repeatedly freezing and thawing until rock breaks
Deforestation is the process of humans removing trees from the environment....explain how this affects soil erosion
Without the roots and the trees acting as a barrier the soil becomes loose and vulnerable to wind erosion
If a mixture of sand, silt, and clay was mixed up in a jar then form layers, what property of soil is this representing?
Particle size
Explain how temperature may weather rock and what kind of weathering is it?
Rocks would become brittle and crack after repeated exposure to different temperatures. In colder temperatures rocks would contract then in hotter temperatures rocks would expand and begin to break.......Physical weathering
Is erosion a constructive or destructive process? Give an example
Constructive some examples include sand dunes, river deltas, and flood plains
Explain why a mixture of clay, silt, and sand is the best kind of soil for plant growth
Because it would be able to retain the water appropriately without the soil drowning the plant or sinking further downwards to prevent the plant from taking in water
