Weathering and soil
| Question | Answer |
|---|---|
| Weathering | natural process by which atmospheric and evironmental agents such as wind, rain, and tempature changes, disintegrate, and decompose rocks. |
| Mechanical Weathering | process by which rocks breakdown into smaller pieces physical means |
| abrasion | the grinding and wearing down of rock |
| chemical weathering | how rock is broken down by chemical reactions |
| acid precipitation | rain sleet or snow that contains ahigh concentrasion of acids |
| differential weathering | breaking down rock with less weather |
| soil | mixtuire rock fragments organic material water and air that can support the growth of vegetation |
| parent rock | rock formation that is the source of soil |
| bedrock | layer of rock beneath soil |
| soil texture | soil quality that is based on the proportions of soil particles |
| soil sdtruture | arrangement of soil particles |
| humus | dark organic material made up of decayed plants and animals |
| leaching | removable substance that can be desolved |
| soil conservation | to protect the soil from erosion to keep nurtrentis |
| erosion | process by wind water ice or gravity transports |
| mass movement | when gravity moves downhill |
| glacier | enormous mass of moving ice |
| creep | slow downhill movement of weathered rock |
| landslide | sudden movement of rock and soil down a slope. |
| mudflow | flow of a mass of mud or rock and soil mixed a large amount of water |
| rock fall | rapid mass movement of rock down a steep cliff or slope |
| control group | participants NOT exposed to the Independent variable |
| experimental group | participants EXPOSED to the Independent variable |
| Controlled Experiment | tests only one factor at a time |
