4.
This is the layer of gases surrounding the planet Earth that is retained by Earth's gravity.

atmosphere

cryosphere

hydrosphere

Scientists have used computer models to create a series of maps that show how susceptible coastal cities and island countries are to the sea rising at different levels. The maps show that a 1-meter rise would swamp cities all along the U.S. eastern seaboard. A 6-meter sea level rise would submerge a large part of Florida. Thermal expansion has already raised the oceans 10 to 20 centimeters.
The MOST likely cause, directly and indirectly, for such a rise in sea level is
The MOST likely cause, directly and indirectly, for such a rise in sea level is
a)
global warming
b)
increased sedimentation
c)
change in ocean salinity
d)
decrease in ocean density
100 %
