Weathering and Soil

QuestionAnswer
rain, sleet, or snow that contains a high concentration of acids Acid Precipitation
Ice, wind, water, gravity, plants, and animals are all agents of Mechanical Weathering
The term for the arrangement of soil particles is Soil Structure
The proportion of different-sized particles in soil determines the soil’s Soil Texture
The removal of substances that can be dissolved from rock or layers of soil due to the passing of water is called Leaching
What is it called when wind blows sand and silt against exposed rock, eventually wearing away the rock’s surface? Abrasion
When oxygen in the air reacts with iron, the result is Oxidation
the process by which softer, less weather resistant rocks wear away and leave harder, more weather-resistant rocks behind Differential weathering
the dark, organic material formed in soil from the decayed remains of plants and animals Humus
the layer of rock beneath soil Bedrock
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
These areas get some water from under the ground, but when it evaporates it leaves behind salts that can kill plants. Desert
. Low soil temperatures and little rain cause soil formation to occur slowly. Because of the temperature, decomposition of plants and animals occurs slowly or stops, limiting the amount of humus in the soil. Arctic
The heavy rain leaches nutrients from the topsoil. Crops can be grown year round because of the warm soil temperature, so plants are using nutrients from the soil yearround. Rainforest
Frequent changes in temperature in this climate lead to frost action, which allows thick, fertile soil to develop. The soils in this climate are some of the most productive in the world. Temperate Forest / Grassland
