# The Greenland ice sheet can be one km thick. Estimate the pressure underneath the ice. (The density of ice is 918 kg/m3.)

The Greenland ice sheet can reach thicknesses of up to one kilometer, creating immense pressure on the underlying land. To estimate this pressure, we must take into account the density of the ice (918 kg/m3) and the force of gravity acting upon it. According to Pascal’s Principle, when an external force is applied to a confined fluid (such as water), it is transmitted equally throughout that fluid. Therefore, we can use this principle to calculate the pressure underneath the Greenland ice sheet.

The formula for calculating pressure is P = F / A where P represents pressure and F stands for Force .Using known variables – including ice density 918 kg/m3 ,gravity 9.81 m/s2 ,and height 1000 meters – we arrive at value 125 N/m^2 or 12500 Pa .This means that if large enough area were exposed beneath surface chunk could bear weight roughly equal 12500 Newtons per square meter.

## The Greenland ice sheet can be one km thick. Estimate the pressure underneath the ice. (The density of ice is 918 kg/m3.)

It is important remember that though result may seem intimidatingly high ,taking into consideration temperature fluctuations within arctic region over time makes figure far more manageable due fact that densities change according outside conditions.. For instance, during winter months snow accumulation adds additional insulation layer thus reducing overall stress while warmer temperatures summertime cause melting which lowers amount weight needs be sustained on same area size ..

Finally ,it worth noting significance these figures not only scientific but also environmental sense since knowing how much stress surface can withstand helps us better understand consequences global warming have polar regions will ultimately lead changes in sea levels across world .. By deepening understanding matter hope further our knowledge climate dynamics well effects thereof in order plan accordingly prevent any disasters might arise from issuing out planet..
