These maps show how the continents would look if you could see gravity

Tech Insider:

Precisely measuring Earth's gravity is surprisingly difficult - we know how strong it is in general, but the force of our planet's pull varies significantly from one part of the planet to another, and detailed maps of that pull offer significant clues to what lies under Earth's surface, not to mention critical information for architects and engineers.

Some of the best maps of Earth's gravity come from the Western Australian Geodesy Group at Curtin University. Geodesy is the mathematical study of Earth's shape and properties. The group combined data from satellites and Earth-bound observation to produce the highest-resolution maps of the planet's gravity ever made. The result: maps of six of Earth's continents by local gravity.

Here's what they look like in North America. Blue regions have lower gravity, while red regions have higher gravity:
