The Effects Of Gravity Remote Measurement In The Earth Surface Essay Samples
The gravity has many applications in the solar system and on Earth surface. It is mainly responsible to keep us ground and the natural climate changes. Moreover, the scientists have developed a tool to measure the approximate of Earth’s gravity. This tool is back up with careful studies and experiments. The advantages and disadvantages such as radioactivity are also included and specify that one cannot eradicate the radiation from the environment.
In space, the gravity is responsible for the planet orbits and other terrestrial bodies in the solar system. It maintains the constant distances between planets and of the sun. It is also responsible for the natural climate changes and landmasses of Earth-from trenches in the ocean up to the ranges of the mountains.
Actually, the NASA and GAC (German Aerospace Center) have developed a tool that can record and measure the Earth’s gravity anomalies. The tool is called as GRACE (Gravity Recovery And Climate Experiment). It’s a satellite craft the records the gravity anomalies and geods of the Earth surface. The gravity anomalies can be determined by the changes of concentration of masses with in a region. Just as the masses of the trenches in the ocean and glacier. While the geods can be calculated without the presence of wind and water- these are represented with maps and approximate distances. The tool generally records the data of millennia ago and up to the present. It can cover the Earth’s gravity field every month from one source and the precision is 100 times accurate than of any existing tool measurements.
It helps us to understand the changes of sea levels, polar ice caps, and ocean current transports. Thus, it can help to differentiate the amount radiation in the environment. There are many people believes that radioactivity is all human-caused, but actually it is not. It’s part of the Earth’s natural process.
