One agent of chemical weathering is ________________, which combines with water to form carbonic acid. Carbonic dioxide
The actions of animals most commonly can cause the type of weathering known as ______________. Mechanical
Rapid chemical weathering can be caused by _______________. Acid rain
Some plants produce acids that result in ___________ weathering. Chemical
The factors that determine the rate are the type of ________ and __________. Rock and climate
Acid rain causes very rapid ___________ weathering. Chemical
The most important agent of chemical weathering is __________. Water
After chemical weathering, the the chemical makeup of the weathered rock is _____________________ than the original rock. Different
Freezing and thawing are an example of ______________ weathering. Mechanical
The movement of rock particles by ice, wind, water, or gravity is called _________. Erosion
The rate of chemical weathering is _________________ in hot, wet climates than in cold dry climates. Faster
The gas that causes rock containing iron to oxidize is ______________. Oxygen
The type of weathering that occurs due to release of pressure is __________________ weathering. Mechanical
Plant roots that force cracks in rocks farther apart an agent of ____________________ weathering. Mechanical
What has a rock probably been chemically weathered by if it contains iron and becomes soft, crumbly, and reddish brown color? Oxygen
What may the growth of plant roots and animal activity result in? Mechanical weathering
What is the agent of mechanical weathering called in which rock is worn away by the grinding action of other rock particles? Abrasion
Granite will last a long time when it is used for building in what type of climate? Cold
What kind of weathering causes the mineral composition of rocks to change? Chemical weathering
What type of climate causes weathering to happen rapidly? Hot and wet
What is ice wedging? Water freezes in rocks and acting like a wedge to break the rock apart.
What is uniformitarianism? The same process that happened in the past thats happening today.
Why does permeable rock weather easily? It has tiny air spaces that allows water to seep into rock.
What can scientist infer from the rounded shape of the Appalachian Mountains? That some rocks are older.
A marble statue is left exposed to the weather. What agent of mechanical weathering probably will cause it to weather? Freezing and thawing
Describe how freezing and thawing of water causes mechanical weathering. When water freezes in a rock, it expands.
Explain how oxygen causes chemical weathering. Oxygen mixes with water to form oxidation
For hundreds of years, an ancient statue had been kept outdoors in a country with a dry, mild climate. A U.S. city bought the statue and placed it outdoors in the park. Predict how the city's climate will affect the weathering of the statue. Some of the reasons why the statue may weather is because of the pollution and the wet climate would cause acid rain, the hot/cold climate may result in freezing and thawing and ice wedging, and he fastest weathering occurs in hot and wet climates.
