WebSurface rupture occurs when movement on a fault deep within the earth breaks through to the surface. NOT ALL earthquakes result in surface rupture. WebMay 6, 2024 · If the blocks of rock on one or both sides of a fracture move, the fracture is called a fault (figure 11). Sudden motions along faults cause rocks to break and move suddenly. The energy released is an earthquake. Figure 11. Faults are easy to recognize as they cut across bedded rocks. Slip is the distance rocks move along a fault.

Second, geologic maps are essential tools for practical applications such as zoning, engineering, and hazard assessment. WebA fault is a crack in Earth’s crust. An intrusion is a body of igneous rock formed within Earth’s crust. When two features intersect, the one that cuts through the other is younger. This is known as the law of crosscutting relationships. Some strata contain index fossils, or fossils associated with a specific time in Earth’s history. northeast florida healthy start
