Prevention & Treatment: Do not plant beans in low-lying, poorly drained areas. Plant beans on raised beds. Plant after the soil has warmed to 69 Â°F at a 4-inch depth. Reduce disease buildup in the soil by rotating locations in the garden where you plant bean or pea with other vegetables.
These collapses can be small, or, as this picture shows, or they can be huge and can occur where a house or road is on top. The most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania. The picture to the left shows a sinkhole that quickly opened up in Florida, apparently eating a swimming pool, some roadway, and buildings.
The place where two plates move apart, or diverge, is called a divergent boundary (dy vur junt). Most divergent boundaries occur along the mid-ocean ridges where sea-floor spreading occurs. Divergent Boundaries. Divergent boundaries also occur on land. When a divergent boundary develops on land, two of Earthâs plates slide apart. A deep valley called a rift valley forms along the divergent boundary. For example, the Great Rift Valley in East Africa marks a deep crack in the African continent.
