Geography(soil)
| Question | Answer |
|---|---|
| What is the study of soil known as? | Pedology |
| Soil is made up of a number of elements and ingredients, what are they? | Mineral matter(rock particles), humus,air,water and living organisims |
| What are rock particles? | Pieces of rock resulting from the processes of weathering and erosion |
| What is humus? | What forms when plants and animals decay and rot. It provides food for living organisms in the soil. The darker the soil the more humus present |
| What is air? | Air contains oxygen and nitrogen, which are vital to a plant life |
| What is water? | Water can make up 25% of soil composition. Water carries dissolved minerals or nutrients to the roots of plants |
| What are living organisms? | Micro-organisms (such as earthworms,woodlice and millipedes) help to break down dead plant matter to form humus |
| What is soil profile? | A cross-section of the soil which reveals layers called horizons |
| What are the horizons? | O horizon(plant litter) A horizon(topsoil) B horizon(subsoil) C horizon(bedrock) |
| What is the A Horizon(topsoil)? | The upper layer of the soil,it contains humus and so is dark in colour. Leaching and hardpan can occur here |
| What is leaching? | In wet conditions,when minerals are washed downwards |
| What is hardpan? | The outcome of leached material. This is an impermeable(water cannont flow through it) layer and the soil may become waterlogged |
| What is the B Horizon(subsoil) | It contains less humus and so is light in colour. It is more stony that A horizon |
| What is the C Horizon? | The bedrock or parent material of the soil |
| What are the factors that influence soil formation? | Climate,parent material, vegetation,living organisms,water and time |
| What are the characteristics of sandy soils? | dry,light and gritty. They are also 70% sand |
| Brown earth soils are found in Ireland, what are the characteristics of brown earth soils? | O Horizon(Deciduous trees) A Horizon(humus,little leaching,dark) B Horizon(less humus,lighter brown) C Horizon(parent material) |

| Brown earth soils are found in Ireland, what are the characteristics of brown earth soils? | O Horizon(Deciduous trees) A Horizon(humus,little leaching,dark) B Horizon(less humus,lighter brown) C Horizon(parent material) |
| Peat earth soils are found in Ireland,what are the characteristics of brown earth soils? | O Horizon(coniferous trees) A Horizon(organic and mineral matter,dark colour,large amount of water) B horizon(grey colour,little air,few organisms) C Horizon(impermeable rock) |
| What is overcropping? | Planting of the same crop in the same area of land area time after time |
| What monocultre? | Farming of a single crop |
