Despite their limited time on earth, humans have been a dominant force of change to earth's systems. very little land or water is left untouched by human activity. humans have been such a force of change that scientists have proposed a new geological time period—the anthropocene or “age of the human.” when would you define as the beginning of the anthropocene epoch?

Match each law or principle to its description. 1. law of original horizontality sediment continues to spread in a flat plane until it hits an edge or runs out of material. 2. law of superposition the youngest strata are at the top and the oldest are at the bottom. 3. law of original lateral continuity sediment gets pulled down by gravity in a horizontal and flat layer. 4. law of cross-cutting or intrusive relationships if there is a fracture or intrusive feature seen in rock strata, it is younger than the rock strata.
