questions to 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 actions of animals most commonly can cause the type of weathering 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 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 chemical makeup of the weathered rock is............ than the original rock. | different |
| Freezing and thawing are and 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 are an agent of......... | Mechanical Weathering |
| What has a rock probably been chemically weathered by if it contains iron and becomes soft, crumbly, and reddish-brown in 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? | Hot |
| What kind weathering causes the mineral composition of rocks to change? | chemical |
| What type of climate causes weathering to happen rapidly? | Hot, Wet |
| What is ice wedging? | Water freezing in rocks and acting like a wedge to break apart. |
| What uniformitarianism | The same process that happened in the past is now happening today. |
| Why does a permeable rock weather easily? | It has tiny air spaces that allows water to seep into rock. |
| What can scientists infer from the rounded shape of the Appalachian Mountains? | They have been weathering for many years. |
| 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 rocks cracks and expands it then unfreeze like( ice wedging) then repeats it again. |
| Explain how oxygen causes chemical weathering. | Iron combines with oxygen and water to form chemical weathering. (Oxidation) |
| Predict how the weathering of the climate will affect the statue? | It will be broken up because of the pollution and wet climate would cause acid rain, Number 2 the hot/ cold climate may result in freezing and ice wedging and fastest weathering occurs in hot/ wet climate. |
