dense

Where Bucharest now stands, there once was a large, dense forest.

The calcification is so dense, it reads like metal.

One factor is the direct effect of logging, which often turns a forest into something approximating a huge pile of kindling (wood for burning): the ground in a logged forest may remain covered with branches and treetops, left behind when the valuable trunks are carted away; a dense growth of new vegetation springs up, further increasing the forest's fuel loads; and the trees logged and removed are of course the biggest and most fire-resistant individuals, leaving behind smaller and more flammable trees.

When a fire finally does start in a sapling-choked forest, whether due to lightning or human carelessness or (regrettably often) intentional arson, the dense, tall saplings (young trees) may become a ladder that allows the fire to jump into the crowns of the trees.

In an ideal world, the Forest Service would manage and restore the forests, thin them out, and remove the dense understory by cutting or by controlled small fires.

The presence of mammal species that require grassland vegetation has led Arctic biologist Dale Guthrie to argue that while cold and dry, there must have been broad areas of dense vegetation to support herds of mammoth, horse, and bison.

The result is insignificant-looking flowers and catkins (dense cylindrical clusters of small, petalless flowers).

Rich clusters, or dense clusters, contain a relatively high number of galaxies.

A regular cluster is sphere shaped, symmetrical, and most dense in the middle.

In the 1840s, when mining operations started, it was a dense green forest.

One type of pattern was of a specific density and was to be classified as dense, while the second type of pattern could vary in density, but was always less dense than the first one.

The denser layers are generally darker than the less dense layers.

Few of the cultural traditions and rules that today allow us to deal with dense populations existed for these people accustomed to household autonomy and the ability to move around the landscape almost at will.

The terrestrial planets are mostly rocks: dense rocky and metallic material, with minor amounts of gases.

How did those dense southern Maya populations deal with the resulting water problem?

They clearly prefer hard wood forests with dense shrubs, bushes underneath the trees.

As evaporation continued, the remaining brine (salt water) became so dense that the calcium sulfate of the hard layer was precipitated.

He's not a bad man, just a bit dense.

Am I being dense? I don’t quite understand.

God！ Frank, please don't look so dense.

The inner zone, its nuclear fires no longer burning, will begin to collapse under the influence of its own weight and will contract into a tiny hot core, dense and dim.

They imagined the deep sea as being filled with an unmoving and undisturbable pool of cold, dense water.

The thick and dense wall of the mound insulates the interior microclimate from the variations in humidity and temperature of the outside atmosphere.

They can only originate and spread in places where there's some dense physical medium, like atmosphere or water.

Astronomers can tell that it lacks a dense core from the details of its gravitational pull on the Galileo spacecraft during several very close flybys.

Soil there is dense and very low in oxygen, so Spartinas have air tubes, air enters through tiny openings on the leaves, the tubes provide direct pipe line for oxygen, carrying it down the leaves through the stems and into the roots, where it is needed.

Both oil and gas are less dense than water,so they generally tend to rise upward through water-saturated rock and sediment.

A dense column of smoke rose several miles into the air.

Likewise, when you get a concentration of cold air, that air's gonna be very dense, so it's gonna create an area of high pressure.

Since water vapor is a greenhouse gas, this humid atmosphere—perhaps denser than Earth’s present-day atmosphere, but far less dense than the atmosphere that envelops Venus today—would have efficiently trapped heat from the Sun.

His prose is vigorous and dense, occasionally to the point of obscurity.
