| Sedimentary rock formed from weathered rock pieces. | Clastic |
| Sedimentary rock formed from the remains of once living organisms. | Organic or Non-clastic organic |
| Sedimentary rock that is formed from substances dissolved in water | Chemical or Non-clastic chemical |
| The process of breaking down rocks | Weathering |
| 4th layer of soil which is solid rock is called: | Bedrock |
| How are sedimentary rocks formed? | The weathering of igneous rocks |
| This is the fastest type of erosion that causes the most erosion world wide. | Running water |
| The top layer of soil: | Topsoil |
| The 2nd layer of soil (B horizon) | Subsoil |
| Type of weathering in which oxygen reacts with metal. | Rusting (Oxidation) |
| 3 processes involved with changing sediments into sedimentary rocks | Compaction of mud; cementation of pebbles; evaporation of water leaves rock behind |
| Type of weathering where trees grow under sidewalks and push them up | Biological weathering |
| What happens to erosion process when people remove trees? | Speeded up |
| Name for decayed plant and animal material | Humus |
| 3 factors that affect the rate rocks weather: | climate, type of rock, amount of rock exposed |
| This type of organic sedimentary rock is formed from compacted shells | Fossil limestone |
| Composed of compacted/cemented mud & clay (Clastic) | Shale |
| Made from plant remains (Organic) | Bituminous coal |
| If it fizzes in HCl acid it must be... | Limestone |
| Used to melt ice in winter to clear roads | Rock Salt |
| Used to Make chalk and buildings | Limestone |
| Large amounts of snow that fall from mountains-caused by gravity | Avalanche |
| the decompostion of a rock | Chemical weathering |
| type of rock that is formed from substances dissolved in water | Non-clatic chemical |
| The process by which sediments are carried away. | Erosion |
| When one rock hits another | Abrasion |
| Large amounts of rocks that fall from a mountain; it is caused by gravity | Landslide |
| List 10 sedimentary rocks | shale, limestone, rock salt, bituminous coal, sandstone, siltstone, fossil limestone conglomerant, breccia, chalk |
| Made from sediment of sand | Sandstone |
| Sediments laid down in a new location | Deposition |
| A cross section of the soil horizons | Soil profile |
| Soils develop and separarte into layers called | Horizons |
| A soil with only two layers is called | Immature |
| The caves in w. VA were formed by what type of weathering? | Chemical |
| Bituminous coal is what type of sedimentary rock? | Non-clastic |
| Landslides, rock slides & avalanches are caused by what type of weathering? | Mechanical - Gravity specifically |
| Type of weathering where water constantly runs over pebble in stream | Mechanical - Abrasion |
| The layer of rock found beneath the topsoil & subsoil is | C Horizon / Saprolite |
| This is formed by rocks breaking down and provides foundation for plants to grow | Soil |
