One of the main ingredients of soil comes from bedrock.
The particles of rock in soil are classified by size as gravel, sand, silt, and clay.

Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down rocks. It is also formed when animals and plant decay.]]> 2022-11-04 16:44:25 UTC https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2370394901 davfracalossi28 https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2370412464 There is the O horizon, A horizon, B horizon, C horizon and bedrock. The O horizon is at the top of the soil, and is made up of organic matter. The A horizon also called the topsoil is a layer of mineral soil that has a defined sol structure, and it is mostly made up of humus.The B horizon is a mineral horizon below the o, and the a horizon in which all or much of the original parent material structures or bedding features have been obliterated. the layer of a soil profile immediately below the B horizon and above the bedrock, composed of weathered rock little affected by soil-forming processes.Bedrock is the hard, solid rock beneath horizons o,a,b,c. Bedrock also underlies sand and other sediments on the ocean floor.]]> 2022-11-04 16:57:36 UTC https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2370412464 davfracalossi28 https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2370418402 Soil is very important to us in many ways. Soil allows plants to grow.

The second cause is water. When it rains the water will slide down a hill or anything with a higher elevation and will pick up a ton of soil. The third is ice/glaciers. Rocks carried by glaciers scrape against the ground below, eroding both the ground and the rocks In this way, glaciers grind up rocks and scrape away the soil. The last cause of soil erosion is gravity. causes the water to slide down hills and pick up soil.]]> 2022-11-04 17:08:54 UTC https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2370427539 davfracalossi28 https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2370428222 2022-11-04 17:09:27 UTC https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2370428222 davfracalossi28 https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2370432260 6 methods of soil conservation are Strip Cropping which happens when different crops are sown in alternate strips to prevent soil erosion. Windbreaks which is a thing, such as a row of trees, fence, wall, or screen, that provides protection from the wind. Crop Rotation which is a system of rotating crops. Cover Crops which is a plant that is used primarily to slow erosion. Buffer Strips which is an area of land along a water body maintained in permanent vegetation that is not tilled or used to grow annual crops. And Grassed Waterways which is plants growing in these contoured pathways that help slow the flow of water and the plant roots help to hold the soil in place.]]> 2022-11-04 17:12:38 UTC https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2370432260 davfracalossi28 https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2373583580 2022-11-07 18:02:09 UTC https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2373583580 davfracalossi28 https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2373584374 2022-11-07 18:02:38 UTC https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2373584374 davfracalossi28 https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2373586895 2022-11-07 18:04:11 UTC https://padlet.com/davfracalossi28/5uiaa0z2aia1npsa/wish/2373586895
