| the type of weathering that occurs due to release is ____________ | mecanical |
| plant roots that force cracks in rocks further apart are an agent of _______ weathering | mechanical |
| if it contains iron and becomes soft ,crumbly,and reddish-brown color what is it called? | iron |
| what may the growth if plant roots and animal activity result in.? | mechanical weathering |
| what is the agent of mechanical weathering called when rock is worn away by the grinding away by rock particles? | erosion |
| granite will last long in what type of climate? | cold |
| what weathering causes rocks minerals to change? | chemical |
| what climate causes rapid weathering | hot and wet |
| what is ice wedging? | it melts and seeps into a deeper crack |
| what is uinfomitaianism ? | when weathering in the past happens today |
| why dose permeable weather happen easily | because it sokes up like a sponge |
| what can scientist infer about the appellation mountains ? | they are older and round |
| what happens to astatue made of marble if it is left outside? what agent of weathering causes it to weather? | freezing and thawing |
| how dose freezing and thawing of water causes mechanical weathering | the weather can change so both |
| how does oxygen causes chemical weathering | oxidation |
| how does the citys climate effect the statue? | pollution and acid rain, freezing and thawing will cause it to expand witch the bolts cant handle and they will break and the hot wet climate oxygen will cause rust. |
