Weathering, Erosion, and Soil

is the process by which rocks on or near Earth's surface break down and change.
Chemical Weathering
changes the chemical composition of rocks.
Weather rate varies
Acid Precipitation
Has a pH value below 5.6
Frost Wedging
The repeated thawing and freezing of water in the cracks of rocks.
It occurs in the decomposition
Measures the pH scale
It is the process by which the other layer of the rock is stripped away.
Buildings and monuments that are made of limestone are greatly damaged by
Acid precipitation
Which of the following factors does not exert pressure on rocks that leads to physcial weathering?
Carbonic Acid
Mechanical Weathering
It is a process by which rocks and minerals break down into smaller pieces and it is also called physical weathering
Temperature and Pressure
Are some of the major factors that plays a significant role in weathering
It determines the effects of chemical weathering
Carbon Dioxide
It is an atmospheric gas that contributes to chemical weathering process
Carbonic Acid
It is when combines with with water and a week acid
Acid Prepcipation
It is another chemical weathering and caused by emission of sulfur dioxide and nitrogen
What climate conditions promote chemical weathering?
Warm Temperature, lots of rainfall, and wild life
What rock type is most easily weathered?
The more surface the more weathering there is.
It is the final stage of the erosional process, which materials are dropped in another location
The force that tends to pull all the materials downhil
The greater the potential for following water to erode earth materials
Coastal areas undergo erosion by
Ocean waves and wind
erode by scrapping, gouging, and picking up large rocks and debris pile
is a major erosional agent in areas with limited precipitation and high temperatures
it is loose covering of weathered rock particles and decaying organic matter overlying the bedrock of Earth's surface
Soil that is located above its parent material is called
Soil that has been moved away from its parent bedrock is called
Soil Profile
It is when heavy machinery digs out soil in the process of building a road, a vertical sequence layers of soil
It is a distinct layer or zone located within a soil profile
In which of the following climates would physical weathering most likely readily occur?
dry and cold
Explain rill erosion and how it differs from gully erosion
Soil cannot process too much water, the rill is a small river in soil which expands into a bigger rilled called a gully.
Describe the formation of barrier islands
Sand Bars on steriods.
