Weathering Questions

QuestionAnswer
What process breaks down rocks, soils, and minerals? weathering
Do all rocks weather at the same rate? No. Some, like lime, weather more quickly. Others, like granite, weather more slowly.
What are some things that can cause weathering? animals, plants, heat, cold, water, ice, pressure, and gravity
Name 3 ways that weathering can be helpful. creates new minerals and new sedimentary rocks, creates soil, creates chemical compounds
True or false? Natural weathering processes occur around us every single day. True. Natural weathering occurs on a daily basis, even though it may only be on a very small scale, such as a crack in a rock expanding ever so slightly.
True or false? As soon as a rock particle moves--whether by wind, water, or ice--we call it weathering. False. Once a rock moves, it is called erosion. Weathering involves the breakdown or decomposition of rocks, not their movement.
Which is not a product created as a result of weathering? the formation of acids soil formation the release of carbon into the atmosphere chemical compounds Chemical compounds, soil formation, and the release of carbon into the atmosphere are all important products created from weathering. Acid formation, however, is not a by-product of weathering.
How does the formation of soil begin? weathering of rocks and minerals
Where can you find more fertile soils? near sources of water
Where can you find less fertile soils? dry, desert areas
What 4 factors influence soil development? parent material, climate, biotic factors, land topography
What is physical weathering? taking a bigger rock and breaking it down into smaller pieces of that same rock. No new chemical substances are created when this process occurs.
What is chemical weathering? causing rocks to break down using chemical reactions. When these chemical reactions take place, new substances are formed.
What two things typically cause chemical weathering? oxygen and acids
Where do acids come from that weather rocks? Acid rain, acid in groundwater, acids produced by living things.
