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