Question 1: Where do acids come from that weather rocks?

Answer:

Acid rain, acid in groundwater, acids produced by living things.

Question 2: 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

Answer:

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.

Question 3: What are some things that can cause weathering?

Answer:

animals, plants, heat, cold, water, ice, pressure, and gravity

Question 4: What 4 factors influence soil development?

Answer:

parent material, climate, biotic factors, land topography

Question 5: Do all rocks weather at the same rate?

Answer:

No. Some, like lime, weather more quickly. Others, like granite, weather more slowly.

Question 6: What is chemical weathering?

Answer:

causing rocks to break down using chemical reactions. When these chemical reactions take place, new substances are formed.Question 7: True or false? Natural weathering processes occur around us every single day.

Answer:

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.

Question 8: Where can you find less fertile soils?

Answer:

dry, desert areas

Question 9: Name 3 ways that weathering can be helpful.

Answer:

creates new minerals and new sedimentary rocks, creates soil, creates chemical compounds

Question 10: Where can you find more fertile soils?

Answer:

near sources of water Question 11: True or false? As soon as a rock particle moves--whether by wind, water, or ice--we call it weathering.

Answer:

False. Once a rock moves, it is called erosion. Weathering involves the breakdown or decomposition of rocks, not their movement.

Question 12: What is physical weathering?

Answer:

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.

Question 13: How does the formation of soil begin?

Answer:

weathering of rocks and minerals

Question 14: What process breaks down rocks, soils, and minerals?

Answer:

weathering

Question 15: What two things typically cause chemical weathering?

Answer:

oxygen and acids
