And the bonding process can happen by either melting and depositing or depositing then melting.

And they said scaling, which is the build up of minerals inside of pipes.

And these are mineral deposits that are also made by bacteria.

The alluvial deposits in Wadi Araba contain important supplies of fresh water.

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

This type of plume often forms bright circular deposits consisting of sulfur dioxide.

Scree deposits are common toward the bottom of many mountains and cliffs.

It contains rocks deposited before the Cambrian Period 540 million years ago.

Canal bottom sediments form as a result of the annual natural channel reshaping process.

Deposits on the bottom of the Caribbean Sea and Gulf of Mexico have a thickness of about 1 km.

These areas may also be important as global sinks for the deposition of carbon.6

12. Preliminary chemical analysis provided some indication of wide spread, low level oil contamination of the fine grained sediments.

These plumes form red (from the short chain sulfur) and black (from the silicate pyroclastics) deposits on the surface.

Volcanic deposits from Alba Mons range in age from Hesperian to early Amazonian (approximately 3600 to 3200 million years old).

Rivers carry sediments hundreds of kilometres, thus affecting downstream activities and contributing to the spread of malaria.

And so in our initial explorations, we were totally focused on exploring the boundary of creation, looking at the volcanic features running along that entire 42,000 miles.

The glacial sediments of the Makganyene formation of South Africa are slightly younger than the Huronian glacial deposits ( 2.25 billion years old) and were deposited at tropical latitudes.

Deposition began approximately 73 million years ago, in the late Campanian, and ended between 68.0 and 67.6 million years ago.

47 million years ago in the Eocene when the Messel deposits formed, the area was 10 further south than it is now.

We go out for months at a time and drill into the sea bed to recover sediments that tell us stories of climate change, right.

Temperatures between 600 and 650 C and pressures between 25 and 150 Pa yield a growth rate between 10 and 20 nm per minute.

It accepts algae and detritus in one end, and through this beautiful, glamorous set of stomach organs, out the other end comes cleaner water.

Quantitative determinations of deposition (mainly throughfall), litterfall and runoff were deemed important to achieve reliable catchment budgets.

And for those who think eating seafood is healthier than land animals, just remember how much irretrievable waste and contaminated sediments are dumped into our oceans.

Ammonia emissions from intensive agriculture are known to cause local pollution effects and excess nitrogen deposition has been identified as a major problem worldwide.

11. The subtidal sediments in the near offshore areas of the ROPME sea area, from Kuwait to Qatar, were found to contain relatively low and uniform concentrations of polynuclear aromatic hydrocarbons.

The study also shows that dams along the river have caused water stagnation, making it saline and hampering the natural process through which fertile sediments would be deposited on the banks.

The sediment contributed from these two rivers forms the Bengal Delta and Submarine fan, a vast structure that extends from Bangladesh to south of the Equator, is up to 16.5 km thick, and contains at least 1130 trillion tonnes of sediment accumulating over the last 17 million years at an average rate of 665 million tons yr.
