Prior to 1900, sea levels rose at maximum, 4 cm per year. Since 1900 sea levels have risen 11 cm per year.
<h3>How sea level is measured?</h3>
Tide stations and satellite laser altimeters are the main tools used to measure sea level.
The height of the sea as measured along the shore in relation to a particular place on land is what tide stations all around the world tell us about what is happening locally.
NASA uses satellites to measure sea level all over the world.
Height of the ocean's surface, often known as sea level, is measured by the Jason-3 satellite using radio waves and other equipment.
It studies how the global sea level is changing over time for the entire Earth every 10 days.
The average sea level is 6,371.001 km (3,958.756 mi), and it is 6,356.752 km (3,949.903 mi) at the poles.
Hydrogen and oxygen are often found in the form of H2O but even if hydrogen surpasses oxygène in number it doesn't when it comes to mass because M(O) = approximately x16 M(H)
