3rd Soil & Erosion
| Question | Answer |
|---|---|
| Topsoil | the uppermost layer of soil It has lots of humus and plants grow well there |
| Subsoil | the layer of soil just below the topsoil |
| Bedrock | the bottom layer of solid rock that lies beneath the subsoil |
| Humus | the decayed remains of plants and animals |
| Clay | this type of soil has the smallest particles; it soaks up water too quickly |
| Loam | a mixture of sand, silt, clay, and humus; many plants grow well in this soil |
| Silt | a soft and smooth soil that can turn dry and dusty; it has smaller particles than sand but larger particles than clay |
| Which type of soil has lots of humus and is great for planting? | Loam |
| Which type of soil has the largest particles, so water runs too quickly through it? | Sand |
| Which type of soil has the smallest particles and is slippery when squeezed? | Clay |
| Which type of soil has bigger particles than clay but smaller than sand? (It can turn dusty). | Silt |
| This type of soil would not be good for planting beacause water would run out of its particles too quickly | Sand |
| The dropping of sediment by wind, water, ice, or gravity is called _____ | deposition |
| This material is in loam and contains decayed remains of plants and animals. It is dark in color | Humus |
| _______ is a force that makes soil and rocks move downhill. | Gravity |
| This type of soil has the smallest particles and absorbs water very fast. It is not the best type of soil for planting, but we have it in Georgia! | Clay |
| This process is the movement of weathered rock material from one place to another | Erosion |
| A ______ is a large mass of slow-moving ice that flows down a slope | glacier |
| ______ is the slow breaking apart or wearing away of rock into smaller pieces. | Weathering |
| A ______ delta is formed by deposition. It is a large mass of dropped sediment at the end of a river. From above it looks like a triangle. | Delta |
| _______ is the best type of soil for planting because it contains a mixture of sand, silt, humus, and clay. | Loam |
