Answer;
-Communities that experience moderate disturbances often exhibit greater species diversity than other communities,
-Moderate disturbances create openings/opportunities for colonizing species
Explanation;
-Ecological disturbances may be generated by abiotic, or nonliving, forces such as weather and wildfires, or they may occur as a result of biotic, or living, forces such as disease and invasions of exotic species.
-Disturbance can result from natural causes or from the activities of humans.
Disturbance can be caused by physical stressors such as volcanic eruptions, hurricanes, tornadoes, earthquakes, and over geological time, glacial advance, and retreat.
-Humans can also cause physical disturbances, for example, through construction activities. Wildfire is a type of chemical disturbance caused by the rapid combustion of much of the biomass of an ecosystem and often causing mortality of the dominant species of the community such as trees in the case of a forest fire.
Rocks erode and sediment is deposited.
No sediment is deposited over a long time
Explanation:
Unconformity can form when rocks erode and sediment is deposited in that process, it can also be a period of non-deposition for a very long time. Unconformity represents a time break in the stratigraphic record.
- There are different types of unconformity.
- Unconformity is due to a period of non-deposition or series of erosion which is followed by deposition of sediments.
- Usually, they are expressed by the presence of unconformable beds or some prolonged erosional surfaces that are preserved.

<span>B. 0 - 12 hours.</span> There are four phases in the continuity implementation. Phase 1 is readiness and preparedness; Phase 2 activation and relocation, which acceptable time period is between 0-12 hours; Phase 3 - continuity operations, acceptable time period is between 12 hrs to 30 days and Phase 4 - reconstruction
