Earth viewed from space

                                      EARTH FROM SPACE


Viewed from space, the most striking feature of our planet is the water. In both liquid and frozen form, it covers 75% of the Earth’s surface. It fills the sky with clouds. Water is practically everywhere on Earth, from inside the planet's rocky crust to inside the cells of the human body.

This detailed, photo-like view of Earth is based  largely  on observations from MODIS,                            Earth from space               
the Moderate Resolution Imaging
Spectroradiometer, on NASA's Terra satellite.
It is one of many images of our watery world
featured in a new story examining water in
all of its forms and functions.
