<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.
