Geologists are likely to make the observation that land is spreading out more and more every year.
The most earthquakes occur in Alaska, followed by California.
the san Andreas faultline lies on the north American plate and the pacific plate
The odds of experiencing an earthquake, at least a tremor in San Fransisco on any given day are pretty good. The west coast of the US, especially California is one of the most geologically active areas of the country. Positioned in such close proximity to so many major and minor faults, earthquakes in most California cities are pretty common.According to the USGS, the probability of the San Francisco area experiencing at least one magnitude 6.7 or greater earthquake in the next 30 years is about 63%, distributed among these faults as follows:Hayward fault about 31%San Andreas fault about 21%San Gregorio fault about 10%Calveras fault about 7%Concord fault about 4%etc.See: http://www.earthquakesafety.com/earthquake-faults.html
The coast of California has a high risk because of it's location on the transform boundary between the North American and the the Pacific plates. In this region stress can build up along the fault where it gets locked in place and this can cause large earthquakes. Another section of the US that is at significant risk of earthquakes is Alaska due to the subduction of the Pacific plate under the North American plate (this caused the largest earthquake in US history in 1964 with a magnitude of 9.2)
If global warming continues, scientists predict that weather events like storms, floods and droughts will become more severe and more common. Ice caps and glaciers will melt causing sea levels to rise. This will affect low lying countries, especially in the Pacific Islands.

Observation
San Andreas Fault located in western Northern America (the one between San Francisco and Los Angeles
The two plates are the Pacific Plate and the North American Plate are the plates causing the San Andreas Fault.
Yes, scientists know what is causing the ozone layer to disappear. It is the continues use of ozone depleting substances.
Because the Pacific plate collided with the North American plate long ago, causing a variety of land phenomena (like the San Andreas fault).
The most earthquakes occur in Alaska, followed by California.
no one cares
Check that your graphics drivers are up to date and that the card is not overheating.
Scientists think that human burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity (which releases carbon dioxide (CO2)), is causing the atmospheric temperature rise.
There are no natural factors that scientists think are causing the present climate change. It is now clear that global warming is caused by deforestation and the burning of fossil fuels (coal, oil and natural gas).
