- 1. Multiple ChoiceWhich of the following is NOT a type of chemical weathering?watercarbon dioxideice wedgingliving organisms secreting acid to break down rocks
- 2. Multiple ChoiceWhat is weathering?The process by which
water, ice, wind or gravity
moves fragments of rock
and soil.The process by which
water, ice, wind or gravity
deposit rock sediments
and soil in a new place.The breaking down of
Earth’s crust into smaller
and smaller pieces. - 3. Multiple ChoiceWhat is erosion?The process by which

- 6. Multiple Choice
What are the two factors that affect the rate at which weathering occurs?climate and mass of rockclimate and size of rocktype of rock and size of rocktype of rock and climate - 7. 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
- 8. Multiple ChoiceWhich of the following is an example of mechanical weathering?Acidic groundwater dissolving limestonefrost wedgingPaper being burned
- 9. 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 - 10. 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.
- 11. Multiple ChoiceThe process that breaks down rocks and other materials on Earth's surface is calledweatheringerosionsoil conservationdecomposition
- 12. Multiple ChoiceWhich type of climate will have faster chemical weathering?Hot and WetCold and DryHot and ColdCold and Wet
- 13. Multiple ChoiceCarbon dioxide (CO2) combines with water as raindrops fall through the atmosphere. This makes a weak acid, called carbonic acid. Carbonic acid is a very common in nature, where it works to dissolve rock. Pollutants, such as sulfur and nitrogen from fossil fuel burning, create sulfuric and nitric acid. Sulfuric and nitric acids are the two main components of acid rain, which speeds up chemical weathering.
This statue was probably destroyed by _____.WindHumansAcid RainAnimals - 14. Multiple ChoiceMechanical weathering increases the rate of chemical weathering. As rock breaks into smaller pieces, the surface area of the pieces increases Figure below. With more surfaces exposed, there are more surfaces on which chemical weathering can occur.
After hit with acid rain, tiny cracks form. Does this make it more likely or less likely to break apart?More LikelyLess Likely - 15. Multiple ChoiceHow do plants weather rocks?during photosynthesiswhen roots grow into cracks of rocks and expand the rockwhen the plant moves water from the roots to the leaves
- 16. 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
