review
| Question | Answer |
|---|---|
| Some plants produce acids which result in _________ weathering | chemical |
| A rock that contains tiny, connected spaces through which water can move is said to be | Permeable |
| One agent of chemical weathering is_________, which combines with water to form carbonic acid | Carbon dioxide |
| The action of animal most commonly can use a type of weather known as_______ | mechanical |
| Rapid chemical weathering can be caused by________, which is rain combined with pollutants | acid rain |
| Some plants produce acids that result in _______ weathering | chemical |
| The factors that determine the rate of weathering are the type of _______ and ______ | rock, and climate |
| Acid rain causes rapid ________ weathering | chemical |
| The most important agent of chemical weathering is _______ | water |
| After chemical weathering, 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 rocks father apart are an agent of ______ weathering | mechanical |
| What has a rock probably chemically weathered by if it contains iron and becomes soft, crumbly and reddish-brown in color? | It probably was weathered by oxygen |
| What may the growth of plants roots and animal activity result in? | mechanical |
| What s 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 it is used from building in what type of climate | cool |
| What kind of weathering causes the mineral composition of rock to change | chemical |
| What type of climate causes weathering to happen rapidly | hot |
| What is ice wedging | Water freezing in rocks and acting like a wedge to break apart |
| What is uniformitarianism | The same process that happened in the past is happening today |
| Why does a permeable rock weather easily | It has tiny air spaces that allow water to seep into the rocks |
| What can scientist infer from the rounded shapes of Appellation Mountains | They have been weathering for many years |
| A marble statue is left exposed to the weather. What agent of mechanical weathering probably cause it ti weather | Freezing and thawing |
| Describe how freezing and thawing of water causes mechanical weathering | Water freezing in rocks and acting like a wedge to break apart |
| Explain how oxygen causes chemical weathering | Iron combines with oxygen and water to form chemical weathering (oxidation) |
| A statue is outside in a hot, rainy summers, freezing winters, and air pollution, how will this weather affect the statue | The pollution and wet climate would cause acid rain, the hot/cold climate would cause freezing and thawing, also the hotter and the wetter the climate it is the faster things will weather |
