the gas that causes rock containing iron ti oxidize is ________________. oxygen
the type of weathering that occurs to release of pressure is ______________ weathering. mechanical
Plant roots that force cracks in rocks farther apart are 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 in color? mechanical
What may the growth of plant roots and animal activity result in? mechanical
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? hot and wet
What kind of weathering causes the mineral composition of rocks to change? cold climate
What type of climate causes weathering to happen rapidly? chemical
What is ice wedging? hot and wet climate
What is uniformitarianism? water freezing in rocks and acting like a wedge to break the rock apart.
Why does a permeable rock weather easily? the same process that happened in the past to today
What can scientists infer from the rounded shape of the Appalachian Mountains? air holes
A marble statue is left exposed to the weather. What agent of mechanical they have been weathering for many years
Describe how freezing and thawing of water causes mechanical weathering. freezing and thawing
Explain how oxygen causes chemical weathering. oxygen mixes with the water to form oxadation
Predict how the city's climate will affect the weathering statue. Give reasons for your prediction. some of the reasons why the statue may weather is because of he pollution and the wet climate would cause acid rain, the hot/cold climate my result in freezing and thawing acid ice wedging and the fastest weathering occurs in hot and wet climates.
