Show Answers:

  1. the soil conservation technique that helps restore nutrients to the soil is called___________
    cover crop
  2. Increasing the surface area of a rock causes the rate of weathering to happen quicker or slower?
  3. Examples of agents that causes mechanical weathering are________
    Ice, wind, water, gravity, plants and animals
  4. In what type of climate does mechanical weathering have a greater rate of occurring?
    cold and wet
  5. the arrangement of soil particles
    soil structure
  6. the soil conservation technique that helps prevent erosion of sloping hills
    contour plowing
  7. What happens when oxygen in the air reacts with iron?
  8. the removal of substances that can be dissolved from rock or layers of soil due to the passing of water is called
  9. the layer of rock beneath the soil
  10. some areas get water from underground. when the water evaporates, it leaves behind salts that can kill plants. What is this area called?
  11. Due to temperature changes, frost action occurs. The soil is thick and fertile. What is the climate in this area?
    temperate forest and grassland
  12. the dark, organic material formed in soil from the decayed remains of plants and animals
  13. in this process, softer, less weather-resistant rocks wear away and leave harder, more weather-resistant rocks behind
    differential weathering
  14. When wind blows sand and silt against exposed rock, and eventually the rocks surface is worn away, what is this called?
  15. what determines the soils texture?
    the proportion of different-sized particles in the soil
  16. when water dissolves a sugar cube, what type of weathering has occurred?
    chemical weathering
  17. what are some benefits provided by soil?
    • provides a habitat for animals
    • allows for water storage for plants
    • provides minerals and nutrients for plants
  18. what benefit does terracing have?
    prevents erosion on steep hills by heavy rains
  19. how does no-till farming reduce water runoff?
    it provides cover
  20. a method to maintain the fertility of the soil by protecting the soil from erosion and nutrient loss
    soil conservation
  21. the process by which wind, water, or gravity transports soil and sediment from one location to another
  22. The climate with low soil temperatures and little rain which causes soil formation to occur slowly. This limits the amount of humus in the soil.
  23. The climate with large amounts of rain and warm temperatures. Plants can grow year round
    tropical rain forest
  24. rain, sleet, or snow that contains a high concentration of acids
    acid precipitation
