PPT-How Soil Forms Chapter 2 Section 2

Pages 48 54 Objective Describe the composition of soil amp explain h ow it is formed and recognize the soil horizons Soil is formed as rock is broken down by weathering and Mixes with other materials on the surface. The soil should be neutral or slightly acidic with pH 65 to 70 having high organic content Very light sandy soils are not recommended owing to their poor moisture holding properties Climate Light Light is one of the most important climatic factors i texturecourtesyNASA: (Getandsample)soilhorizonsmallthesprayLetthebetweenthemoisturethroughout.OncetheStepStep(TestIf the soil: handswhenrubbedandStep themediumribbon mean to . roses. ?. Aka, what can I use to grow a healthy garden of roses and maybe even a “Queen” of show?. How your rose bush . makes food . Your. rose bush takes in carbon dioxide from the air, water and nutrients from the ground and makes sugars and starches (the source of energy to do that is sunlight and the reaction is known as photosynthesis). These building blocks in rose bushes are technically known as carbohydrates (carbon and water). The plant uses these to grow and make beautiful roses. The plant does not need the oxygen left over from the carbon dioxide and so the plant releases oxygen back into the atmosphere.. What is soil?. Rocks and sediments might not seem to have much in common with soil, but soil is what they become when they are weathered.. Soil. is the loose, weathered material on Earth’s surface in which plants can grow!. Soil is a mixture of. rocks, minerals, decayed. material, water, and air.. Soil is one of Earth’s most valuable natural resources. . Everything . that lives on the land, including humans depends on soil.. Are they different? and . Do they matter?.
