Answer:
Natural processes such as waves, tides, and weather, continually change coastal landscapes. The integrity of coastal homes, businesses, and infrastructure can be threatened by hazards associated with event-driven changes, such as extreme storms and their impacts on beach and dune erosion, or longer-term, cumulative changes associated with coastal and marine processes, such as sea-level rise. Scientists working on Coastal Change Hazards conduct basic and applied research and provide relevant science-based products to assist the Nation with these coastal change hazard challenges. By building a community with a broad range of expertise, CCH facilitates the integration of diverse coastal science and the exchange of new ideas and approaches across the Coastal-Marine Hazards and Resources Program (CMHRP). Innovative collaboration is encouraged in order to identify and address the Nation’s needs and coastal change hazards problems. Through observation and modeling, CCH develops robust and accessible coastal change assessments that help improve the lives, property, and economic prosperity of the Nation’s coastal communities, habitats, and natural resources.

Answer:
The correct answer is A. Country X has the higher natural increase rate.
Explanation:
Natural increase rate is the excess of fertility over mortality, that is, the difference between the number of births and deaths over a period of time; making the basis for population growth.
As Country X has a crude birth rate of 40 and a crude death rate of 15, its population's natural increase rate is 25. In turn, Country Y has a crude birth rate of 20 and a crude death rate of 9, so its population's natural increase rate is 11. So, as we can see, Country X has a higher natural increase rate.
