- 2. Multiple ChoiceThe process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.weatheringerosiondepositiondumptruck
- 3. Multiple ChoiceThis type of weathering occurs when rock is physically broken down into smaller pieces of rock.physical weatheringchemical weatheringerosion weatheringdeposition
- 4. Multiple ChoiceThis type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.physical weatheringchemical weatheringerosion weatheringdeposition
- 5. Multiple Choice
These rocks were made smooth by wind blowing smaller rock particles across their surface. This is an example of:ice wedgingchemical weatheringacid rainabrasion - 6. Multiple ChoiceThese rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:ice wedgingacid rainpermeabilityabrasion
- 7. Multiple ChoiceThis rock may chemically weather easily because is has many spaces or holes in it that allow water to seep through it, meaning it is:permeableabrasiveerosionunchangable
- 8. Multiple ChoiceThese gravestones have slowly broken down and turned a blackish color due to the action of:ice wedgingabrasionacid rainphysical weathering
- 9. Multiple ChoiceHow might a weathered mountain appear different than an unweathered mountain?Weathered mountain would be taller.Weathered mountain would be rounder and less jagged.Weathered mountain would be more jagged and less rounded.Weathered mountain would have no trees.
- 10. Multiple ChoiceHow is physical weathering different from chemical weathering?Chemical weathering happens over much shorter time frame than physical weathering.Chemical weathering changes the chemical composition of rocks; physical weathering does not.Chemical weathering occurs only in tropical climates; physical weathering occurs only in cool climates.Chemical weathering occurs only in the mountains; physical weathering occurs only on flat land.
- 11. Multiple ChoiceWeeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:physical weatheringchemical weathering
- 12. Multiple ChoicePotholes forming in the road after a cold winter is an example of:physical weatheringchemical weathering
- 13. Multiple ChoiceA metal statue slowly turning green after years of being outside is an example of:physical weatheringchemical weathering
- 14. Multiple ChoiceRocks along a riverbed that are smoothed from continuously moving water and sediment rubbing against them is an example of:physical weatheringchemical weathering
- 15. Multiple ChoiceA piece of sandstone changing color (from brown to rusty red) from exposure to water and air is an example of:physical weatheringchemical weathering
- 16. Multiple ChoiceThe formation of stalactites and stalagmites in a cave as water mixed with carbon dioxide creates carbonic acid, which dissolves away the limestone, is an example of:physical weatheringchemical weathering
- 17. Multiple ChoiceThe formation of large cracks in the face of a mountain from ice wedging is an example of:physical weatheringchemical weathering
- 18. Multiple ChoiceAcid rain wearing away the face of a marble gravestone or statue is an example of?physical weatheringchemical weathering
- 19. Multiple ChoiceExposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart. This is an example of:physical weatheringchemical weathering
- 20. Multiple ChoiceLichens (small green plants) growing on a large boulder release enzymes and other acids that slowly break the rock apart. This is an example of:physical weatheringchemical weathering
- 21. Multiple ChoiceWhich of the terms describes the process of acid rain wearing away limestone?Cryptic ErosionChemical WeatheringCryptobiotic WeatheringChemical Erosion
- 22. Multiple ChoiceThe process that breaks down rocks and other materials on Earth's surface is calledweatheringerosionsoil conservationdecomposition
- 23. Multiple ChoiceHow does freezing water cause the weathering of rocks? The freezing water—keeps the rocks in placemakes the rocks last longerexpands cracks and breaks rockscauses rocks to fall in landslides
- 24. Multiple ChoiceAll of the following are causes of physical weathering except...plant growthwindacid rainrunning water
- 25. Multiple ChoiceWhat is physical weathering?Process through which rocks are physically broken into smaller pieces.Rocks are broken down through chemical changes.Rocks are worn away from acid in plant roots.Rocks broken down by machinery.
- 26. Multiple ChoiceWeathering can change roads, sidewalks, buildings and sculptures over time.FalseTrue
- 27. Multiple ChoicePhysical weathering breaks down existing rocks byChanging them chemically, but not physically.Changing them physically, but not chemically.Changing them chemically and physically.
