The presence of corals and trilobites with well-developed eyes and the rarity of plant fossils from the central basin areas suggest a shallow-water environment.

The central basin has an area of 8.6km2 sqmi with intertidal flats having an area of approximately 2km2 sqmi.

The gardens are a classical composition of lawns, avenues, eight parterres around a central basin, hedges, and small groves of trees.

The sea covered more than one million square kilometers in the central basin area.

The inlets have a total area of 15.8 km2, most of the area being found in the central basin.

Fill the basin with the pudding mixture and top with the greaseproof paper disc.

Aspects of the sediment, namely its composition, primary structures, and internal architecture, can be synthesized into a history of the basin fill.

The initial basin fill was a variable sequence of sandstones and minor volcaniclastic sediments.

Most lakes are geologically young and shrinking since the natural results of erosion will tend to wear away the sides and fill the basin.

One corner of the lake has little rock basins filled with extremely hot water, converting the whole thing into a natural spa.

Snow cover in the lake basin persists for 180 to 200 days a year.

However, affected by the complicated topography of the lake basin, there are some differences in pollen assemblages from different sites of the lake basin.

There are 50 mi of trails offering a variety of one way and loop trips into the lake basin areas and mountain summits.

About 200 bird species from 15 families have been observed in the lake basin.

The lake basin provides an important habitat for woodland caribou.

Most of the discoveries were made in an ocean basin that could have been isolated from other ecosystems for millions of years.

Its 180-decibel-plus bellows, below our range of hearing, could conceivably carry through a deep, cold layer of seawater across an entire ocean basin.

At the edge of the ocean basin, 200 million years later, they will slide beneath the lighter continental crust in a final volcanic firework display.

The great quantities of dense water sinking at polar ocean basin edges must be offset by equal quantities of water rising elsewhere.

This incipient ocean crust remains locked to the continental margin when the ocean basin closes, emplacing the incipient ocean crust into the collision zone.

A bathroom — portable loo, water basin, small mirror — was installed in the vestry.

Pastures equal 793.1 hectares, forests - 2263.7 and water basin 329.4 hectares.

A large water basin was heated for the tropical marsh flora.

Menace of oil pollution of the water basin and littoral (coastal) ecosystems.

A water basin, comb, and powder brush are all displayed on the table.
