- 1. 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
- 2. Multiple ChoiceThe process that breaks down rocks and other materials on Earth's surface is calledweatheringerosionsoil conservationdecomposition
- 3. Multiple ChoiceHow does wind abrasion work?Sediment is blown off a surface from wind.Wind-blown sediment strikes a surface.Wind blows large chunks of rock off a surface.Sediment falls off of a surface on its own.
- 4. Multiple ChoiceWhat is mechanical 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.
- 5. Multiple ChoiceWhat is permeable?a material that is softa material that is full of tiny air spaces that allow water to seep through ita material that is able to be broken and re-attacheda material that is able to be created into a different substance
- 6. Multiple ChoiceWhich type of climate will have faster chemical weathering?Hot and WetCold and DryHot and ColdCold and Wet
- 7. Multiple ChoiceDuring chemical weathering, what can happen to the type of rock that has undergone chemical weathering?a new rock is produced that is larger than the original rocka new rock is produced that is the same as the original rocka new rock is produced that is different from the original rockno new rock is created - it is just smaller in size
- 8. Multiple ChoiceThe diagrams shows a natural process that weathers rock.
Which statement best explains why this process results in weathering?frozen water acts as a solutewater expands when it freezesthe mass of water increases when it freezesfrozen water dissolves most types of rock - 9. Multiple ChoiceWhich of the following is an example of mechanical weathering?Acidic groundwater dissolving limestonefrost wedgingPaper being burned
- 10. Multiple ChoiceA marble statue is left exposed to the weather. Within a few years, the details on the statue have begun to weather away. This weathering probably is caused by...oxygen in the aircarbonic acid in rainwaterlichensabrasion
