Each sand grain is about a tenth of a millimeter in size.

The mass balance between sediment being transported and sediment in the bed is described by the Exner equation.

So what have we learned from these animals with a brain that's the size of a grain of rice?

And that alternates with a sediment that looks like this.

It has wings, it has eyes, it has antennae, its legs, complicated life history, it's a parasite, it has to fly around and find caterpillars to parasatize, but not only is its brain the size of a salt grain, which is comparable for a fruit fly, it is the size of a salt grain.

This sediment is 100 percent made up of the shells of microscopic plants.

Erosion accelerates as the mountains rise, and great volumes of sediment are shed into the rivers, which carry sediment away from the mountains to be deposited in sedimentary basins in the surrounding lowlands.

It's trying to walk on the coarse terrain, sandy area, but depending on the moisture content or the grain size of the sand the foot's soil sinkage model changes.

Here the river slows considerably, dropping sediment that might otherwise form a river delta.

Three sheets of sediment have been found on top of the lava that lies below the city and, mixed in with the sediment, archaeologists have found bits of animal bone, pottery shards and plants.

And when you're squinting, what you're doing is you're turning that from fine grain to coarse grain.

As the trees fell, the fine sediment in which the forest grew protected the plants.

Lots of evidence from sediment cores and the pollen types, oxygen isotopes and so on.

Rivers washed sediment into the seas, until the organic remains of the algae were buried.
