layer

A thin layer of dust covered everything.

See, the carton contains thin layer of wax laminate.

Now one important characteristic of snowflakes is that they have something called a quasi-liquid layer, the QLL.

Well, we find a quasi-liquid layer on the surface of ice is basically a thin layer of water that’s not completely frozen.

Now this quasi-liquid layer, it plays an important role on what we are going to talk about next.

There is a layer of water molecules on the surface, they attached molecules only on one side.

But that top layer, it only has a layer below it.

But the bricks of water molecules, well, this top layer would be the quasi-liquid layer.

Now there is the ozone found in the stratosphere which is the layer of the atmosphere from 6 to 30 miles above the Earth.

Now snowflake’s quasi-liquid layer plays an important role in some complex chemical reactions.

So the more branches you have in an ice crystal, the more quasi-liquid layer there is.

The more quasi-liquid layer, the more reactions and the more chemicals that reduce ground-level ozone.

A waning flood might deposit a layer of gravel, overlain by sand and finally topped by silt and clay.

He found that the deeper the water, the colder it got, and he concluded that the seafloor was covered with a thick layer of ice.

The mature ponderosa trees have bark two inches thick and are relatively resistant to fire, which instead burns out the understory - the lower layer - of fire-sensitive Douglas fir seedlings that have grown up since the previous fire.

So for example, sometimes, thin reed mats were stuck onto the walls, so these thin reed mats would be like an additional layer between the original part of the wall and the frescos, the painted part of the walls that were done over them.

Other times though, plaster was applied directly to the walls, a thick layer of plaster, to fill in spaces between the bricks, to smooth out the wall surface for painting the fresco.

Actually, what happens is that the waves caused by the winds build a sort of protective layer of sediment.

So the active layer of permafrost thaws faster than the water can drain from the soil.

That is the areas where the ground, the soil, is always frozen, except for the very top layer, what we call the active layer of permafrost, which melts in the summer and refreezes again in the winter.

Then in the summer, when the active layer, the top layer of the permafrost, melts, the melt water runs into those cracks in the permafrost, then freezes again, because that ground, the ground beneath the active layer is still below freezing.

Then in the autumn, the active layer on top freezes again.

So the next summer when the active layer melts again and flows into the widened cracks and freezes, it makes the cracks even wider.

So when the ice wedge reaches a certain size, its top part in the active layer turns into a little pond when it melts in the summer.

From the oldest soil layer dating back 10,000 years, they found evidence of pits, stake holes and ditches.

The second phase, which they identify from a higher layer of soil, featured regularly distributed mounds.

The western Pacific develops a thick, warm layer of water while the eastern Pacific has the cold Humboldt Current enhanced by upwelling.

As far as the extraction process the petroleum industry digs deep wells to reach underground oil fields where crude oil has accumulated over a large area and extract between layers of rocks.

And that creates distinct layers of soil as far down as the rock underlying the soil.

Stromatolites look like wavy layers of sedimentary rock, but they are really fossils, fossils of the waste from microbial masts.

Layer the potatoes in a dish.

They're layered over each other.

They're layered in such a way that the silicon nano particles don't pack together tightly.

The arrangement of the biological mass ("biomass") of the vegetation into layered forms is termed its “structure” (as opposed to its “composition”, which refers to the species of organisms forming the community).

The dancers were filmed and layered in the editing room.

He layered pieces of glass and used thin copper strips instead of lead, which let him make these really intricate flowery designs for stained-glass, which he used in lamp shades.

So, layered glass, Tiffany glass, became very popular and still is today.

Proxy temperature records have been reconstructed from ice core drilled out of the central Greenland ice cap, calcite shells embedded in layered lake sediments in Western Europe, ocean floor sediment cores from the tropical Atlantic Ocean, ice cores from Peruvian glaciers, and ice cores from eastern Antarctica.

There were two many layers of management in this company.
