One theory suggests that the Great Sphinx of Giza formed — in part — naturally as a result of erosion, and ancient Egyptians added features to the bedrock formation. To Keep reading

Painting in Sediment
Pale plumes of sediment flow off these islands in the Gulf of Mannar between India and Sri Lanka. As waves erode the land, currents and tides carry the sediment outward, Keep reading
Why We Can’t Control Rivers
Rivers are systems in a constant state of change, balancing flow speeds, path length, sediment deposition, and erosion, as seen in this previous Practical Engineering video. The next video in Keep reading
Snow-Covered Trees
In the Hakkōda Mountains of Japan, snow encases the trees, transforming the ski slopes into a hoodoo-filled winter wonderland. Photographer Sho Shibata captured these images while journeying through the area Keep reading
Why Rivers Shift
In their natural state, rivers are variable in their course, shifting and meandering. Sometimes they deposit sediment, and sometimes they erode it. In this video, Grady from Practical Engineering digs Keep reading
Sedimentation After Flooding
The new year brought California a series of atmospheric rivers that poured record amounts of water onto drought-stricken lands. While the precipitation refreshed snowpacks and reservoirs, much of it washed Keep reading
The Delta Series
It’s easy in the rush of our daily lives to forget just how dynamic rivers are. In his “Delta Series” conservation photographer Paul Nicklen explores that ever-changing nature from above Keep reading
Eroding Grains
When a spacecraft comes in for a landing (or a tag similar to what OSIRIS-REx did), there’s a turbulent jet that points straight into a bed of particles. How those Keep reading
Frozen Wind-Sculpted Sands
On the cold, wind-swept beaches of Lake Michigan, the sands sometimes turn into a landscape of miniature hoodoos. Strong winds erode the frozen sand into these shapes, which last only Keep reading
“Ruin of the Tides”
As tides and waves flow back and forth over a beach, they erode the sandy shore. Here photographer Michael Shainblum captures the streaks and rivulets left by a falling tide. Keep reading
