Satellite measurements offer scientists a new view of our planet.

Warm colors (red, orange, yellow) represent areas with strong gravity. Cool colors (green, blue) represent areas with weak gravity.

Mountain ranges, such as the Himalayas, have a high concentration of mass, and therefore have a strong gravity field.

Ocean trenches, such as the Mariana Trench, have a low concentration of mass, and therefore have a weak gravity field.

Undersea mountains that line this section of the Mid-Atlantic Ridge contribute to the strong gravity field observed in this region.
