Question

question 11 (1 point) which of these is not one of the four main components of soil? a plastic b air c water d organic matter question 12 (1 point) soil texture affects which property the most? a ph only b color c water retention d temperature question 13 (1 point) why is understanding soil important for the future? a so we can turn it into construction material b because it changes color quickly c to help protect and use it wisely for agriculture and ecosystems d so we can remove it completely

Explanation:

Question 11: The four main components of soil are minerals, organic matter, air, and water. Plastic is not one of them.
Question 12: Soil texture has a significant impact on water - holding capacity. Finer - textured soils can hold more water compared to coarser - textured soils. It has less impact on pH, color, and temperature compared to water retention.
Question 13: Understanding soil is crucial for agriculture as it affects plant growth and for ecosystems as soil is home to many organisms. Protecting and using it wisely is important rather than turning it into construction material, removing it completely, or because of its color - changing properties.

Answer:

Question 11: A. Plastic
Question 12: C. Water retention
Question 13: C. To help protect and use it wisely for agriculture and ecosystems
