The Tripping Point in a climatic system is a threshold that exceeds and can lead to changes in the state of system potential points like those of the physical climatic system like the global carbon cycle and these include the land-use changes and global oceanographic and loss of biodiversity integrity.
The atmospheric tripping point is related to the carbon cycles and the increasing temperature records and geologically rapid rates of transformation between the different climates.
This reflecting on the planet's heat and temperature records due to an increase of the Co2 emissions which in turn is resulting increasing of the greenhouse gases.
The other tipping point is an increase of sea levels and the melting of the ice sheets and collapse of the monsoon Asia and which is linked with that of the environmental changes taking place over the ecologic realms and hot spots over the world.
The type of plate boundary that exists along the San Andreas fault is the transform plate boundary. The tectonic plate that is in California is the Pacific plate and the North American plate
Sand can be trucked in from other sources and filtered for sediments to eventually make way into the air and water. They can also build seawalls, revetments, and jetties along the shoreline. :)
