Answer:
hello
Explanation:
altimeter is your answer
Answer:
Sea level
Tide gauges and satellites laser altimeters are the main tools to measure sea level. The height of the sea as recorded along the shore in relation to a particular place on ground is just what tide sensors all around the world tell us about what is happening locally.
Explanation:
The pressure begins to decrease as we rise above sea level. Since there is a relationship between atmospheric pressure and height above sea level, one can use this feature to determine the height above sea level of a certain location while taking other factors into consideration.
Mean sea level (MSL, frequently abbreviated as sea level) is the average surface level of one or more of the Earth's coastline waterbodies, which can be used to gauge heights like elevation. The global MSL is a standard geodetic datum that is used as a form of vertical datum, The midway between a mean low and mean high tide at a certain area is a more typical and simple mean sea-level criterion.
Numerous variables can alter sea levels, which are known to have changed significantly throughout geological time spans. Sea level increase throughout the 20th century and the present century, however, is thought to be a result of climate change[2], and careful monitoring of MSL changes can shed light on contemporary global warming. Populations affected by climate change-related sea level rise will need to invest in adapting to climate change to ameliorate the worst effects, or when population numbers are in severe risk, a process controlled retreat, because the majority of human settling and infrastructural facilities was built in reply to a more normalised sea level with restricted anticipated increase.
