| Weathering I | ||
| #1 | This is the process involves reactions that dissolve or alter the minerals in rocks or change them into different minerals. | What is chemical weathering? |
| #2 | This is the process by which rocks are broken apart by physical processes. | What is mechanical weathering? |
| #3 | This is a type of mechanical weathering where water enters cracks in rocks and freezes putting pressure on the rock that can cause it to break apart. | What is ice wedging? |
| #4 | Rocks that have smaller amounts of this experience accelerated weathering due to the exposure to water and oxygen. | What is surface area? |
| #5 | These 3 terms are used to describe specific particle sizes of weathered rock and are also referred to as sediment. | What are sand, silt, and clay? |
| Weathering II | ||
| #1 | These two organisms can cause cracks in rocks due to root growth or burrowing. | What are plants and animals? |
| #2 | This type of chamical weathering occurs when materials are exposed to oxygen and water. | What is oxidation? |
| #3 | This is the name of the scale that measures the strength of acids and bases. | What is pH scale? |
| #4 | This affects the soil temperature and moisture and also affects the rate of mechanical and chemical weathering. | What is climate? |
| #5 | These two types of acids weaken rand weather rocks by dissolving minerals in the rocks. | What are natural acids and plant acids? |
| Soil Formation | ||
| #1 | This is a mixture of weathered rock, decayed organic matter, mineral fragments, water, and air. | What is soil? |
| #2 | This is the dark colored material that comes from the decayed organic material. | What is humus? |
| #3 | These three things add organic matter to soil. | What are plants, animals, and microorganisms? |
| #4 | This is the name of the soil type in Murphysboro. | What is temperate? |
| #5 | These are the five factors that affect soil formation. | What are climate, slope of land, types of rock, types of vegetation, and amount of time the rock has been weathering? |
| Soil Profiles | ||
| #1 | This is the soil horizon that contains the litter including leaves, twigs, and other organic material. | What is the O horizon? |
| #2 | This is the process by which dissolved minerals seep into horizon B from horizon A. | What is leaching? |
| #3 | This is the soil horizon that is most similar to the parent bedrock. | What is the C horizon? |
| #4 | This is the horizon that contains the most organic material. | What is the A horizon? |
| #5 | This is the horizon that is darkest in color | What is the A horizon? |
| Erosion | ||
| #1 | When vegetation is cleared, this can occur to soil. | What is erosion? |
| #2 | These are three ways in which clearing vegetation can lead to erosion. | What are agricultural cultivation, forest harvesting, and overgrazing? |
| #3 | This is a process in which plant stalks are left in the field and the soil is not plowed. | What is no-till farming? |
| #4 | This process slows the flow of water down slopes and prevents gullys. | What is contour farming? |
| #5 | This process allows farmers to grow crops on very steep hills and mountains. | What is terracing? |
| Final Question | |
| These are all of the materials that make up soil. | What are rock and mineral fragments (sand, silt, and clay), organic matter (humus), air, and water |
