Depends on the context. If you told more then I could help.
Earth's atmosphere has a series of layers, each with its own specific traits. Moving upward from ground level, these layers are named the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Hope this helped.
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.
Explanation:
If we look at the average American footprint -2-3 of that is made of of carbon emissions. this means that for the four earths we would need if everyone consumes like an American.
If I'm not wrong, that would be the prime meridian. The prime meridian is the line of 0 longitude.
