Soil By: Lucas Wheeler

What is the definition of silt?

• soil component that feels like powder because of its small grain size; particles are smaller than sand but larger than clay
• a description of he shape and size of the particles that make up a rock or soil; sand, silt, clay are examples
  
• makes up the first inches of soil, contains large amounts of humus, water, and living organisms, contains nutrients that plants need in order to grow and develop, easily eroded
• is the layer of the Earth that is composed of soil, and it is where soil-forming processes occur

What is the definition of soil?

• configuration of surface feature, including position and slope; also influences types of soils that develop
• water that flows over Earth's surface and is redeposited into water basins such as lakes, rivers, streams, and oceans
• mixture of weathered rock, organic matter, water, and air, that evolves over time and supports the growth of plant life
• soil component that has a very large grain size, a gritty texture, and does not hold water well

What is the definition of Topography?

• I dont know...
• configuration of surface feature, including position and slope; also influences types of soils that develop
• soil component that has a small grain size, a sticky texture, and can hold water better than any other component
• soil component that has a very large grain size, a gritty texture, and does not hold water well
  

water that flows over Earth's surface and is redeposited into water basins such as lakes, rivers, streams, and oceans is the diffintion of what?

• runoff
• loam
• sand
• clay

soil component that has a very large grain size, a gritty texture, and does not hold water well is the definition of what?

• Runoff
• loam
• sand
• clay

soil component that has a small grain size, a sticky texture, and can hold water better than any other component is the definition of what? 

• Runoff
• loam
• sand 
• clay

soil that contains a mixture of sand, silt, and clay; they have the best characteristics of each of the soil components, it is loose and has a gritty texture, a balanced porosity and permeablility is the definition what?

• runoff
• loam
• sand
• clay

What is the definition of pore space?

• soil component that feels like powder because of its small grain size; particles are smaller than sand but larger than clay
• the spaces between particles of soil; water and air can be found here
• soil component that feels like powder because of its small grain size; particles are smaller than sand but larger than clay
• soil component that is dark in color and is made up of decomposed organic material; usually found in the top layer of soils

What is the definition of humus?

• soil component that is dark in color and is made up of decomposed organic material; usually found in the top layer of soils
• a description of the shape and size of the particles that make up a rock or soil; sand, silt, clay are examples
• makes up the first inches of soil, contains large amounts of humus, water, and living organisms, contains nutrients that plants need in order to grow and develop, easily eroded
• below the topsoil, has less humus, often has more clay and is packed more tightly than topsoil, water gets trapped in this horizon, does not erode easily, plants do not grow as well in this horizon

What is the definition of soil texture?

• below the topsoil, has less humus, often has more clay and is packed more tightly than topsoil, water gets trapped in this horizon, does not erode easily, plants do not grow as well in this horizon
• makes up the first inches of soil, contains large amounts of humus, water, and living organisms, contains nutrients that plants need in order to grow and develop, easily eroded
  
• a description of the shape and size of the particles that make up a rock or soil; sand, silt, clay are examples
• mineral portion of the soil is formed, can be weathered rock from bedrock underneath, or it can be material that was deposited by wind, water, or ice
