Then you could measure sea level accurately. If you did this, the level of the ocean's water projected across the entire planet would be called the geoid. On land, you can think of the geoid as the level that ocean water would have if you were to dig a canal from the ocean's ...
These geographic variations were resolved in 1993 when two satellites were launched that use radar to measure the level of the ocean very precisely from space. This high-tech approach eliminates the problems of land motion on Earth and has given us a new global sea-level rise rate over the p...
If global warming causes the polar ice caps to melt, how much will the oceans rise? What causes high tide and low tide? Why are there two tides each day? How do they measure "sea level"? How much water is there on the Earth? What is a Nor'easter? Why would there be no more fi...

The height of mount Everest is often referred to as altitude, which is the height difference between the summit and sea level. Then how to measure the height of Mount Everest? The measurement of the peak position can use the global positioning system (GPS), its error can be within a centi...
s, and many of the world’sglaciers, are all slowly melting. The runoff feeds into rivers and directly into the oceans. This too adds to sea levels. Prior to the use of satellite systems, measurements were taken using tide-gauges, devices that measure the height of a water level relative...
Measure the total time from the very first clap to the very last echo. In that time, sound has traveled a total of 20 × 2 × 100m (or the distance between you and the wall), which is about 4000m (4km). To find the speed of sound, divide the total distance by the total time...

EMIT is proving to be a key tool in our toolbox to measure this potent greenhouse gas – and stop it at the source.” Orbiting the Earth every 90 minutes from its location aboard a space station about 400 kilometers high, EMIT is able to scan vast stretches of the planet tens of ...
