NASA has put to rest any speculations that Earth maybe expanding or contracting. New research has found that there has been no statistically significant expansion of the solid Earth.
Tectonic forces like earthquakes and volcanoes push mountains higher, while erosion and landslides wear them down, helping to change the Earth's shape. However, despite the facelift, this new research - using space measurement tools and a new data calculation technique - says Earth's size will remain the same.
Researchers referenced their measurements against the International Terrestrial Reference Frame established by the global science community. This reference frame is used for ground navigation and for tracking spacecraft in Earth orbit .... http://www.redorbit.com
