At one astronomical unit from the sun ( the Earth's distance ) the dust orbits are probably nearly circular.

At the peak of the Cretaceous transgression, one-third of Earth's present land area was submerged.

At the Survey, he worked mainly in geodesy and gravimetry, refining the use of pendulums to determine small local variations in the Earth's gravity.

At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground.

At the close of the 20th Century, all of the Earth's kaiju have been collected and confined in an area known as Monster Island, by the United Nations Science Committee, in the Ogasawara island chain.

At its height, the British Empire covered a quarter of the Earth's land area and comprised a quarter of its population.

The idea was used by Edgar Rice Burroughs, the creator of Tarzan, in the seven-novel " Pellucidar " series, beginning with At the Earth's Core ( 1914 ).

At that time it had lost the first page, but the second ( the current beginning of the Ynglinga Saga ) starts Kringla heimsins, " the Earth's circle " of the Laing translation.

At Standard Sea Level conditions ( corresponding to a temperature of 15 degrees Celsius ), the speed of sound is 340. 3 m / s ( 1225 km / h, or 761. 2 mph, or 661. 5 knots, or 1116 ft / s ) in the Earth's atmosphere.

At Earth's orbit its typical density is 6 ions / cm < SUP > 3 </ SUP > ( variable, as is the velocity ), and it contains a variable interplanetary magnetic field ( IMF ) of ( typically ) 2 – 5 nT.

At 10-15 kilometers ( 6 – 9 miles ) above the Earth's surface, the absorption of sunlight would further heat the smoke, lifting some, or all of it, into the stratosphere, to where the smoke would persist for years, with no rain to wash it out.

At 165. 25 million square kilometres ( 63. 8 million square miles ) in area, this largest division of the World Ocean – and, in turn, the hydrosphere – covers about 46 % of the Earth's water surface and about one-third of its total surface area, making it larger than all of the Earth's land area combined.

At first, oxygen would quickly combine with other elements in Earth's crust, primarily iron, as it was produced.

# At the Earth's Core ( 1914 )

The first novel was filmed as At the Earth's Core ( 1976 ), directed by Kevin Connor and starring Doug McClure as David Innes and Peter Cushing as Abner Perry.

At, Russia is the largest country in the world, covering more than one-eighth of the Earth's inhabited land area.

At standard temperature and pressure, radon forms a monatomic gas with a density of 9. 73 kg / m < sup > 3 </ sup >, about 8 times the density of the Earth's atmosphere at sea level, 1. 217 kg / m < sup > 3 </ sup >.

At the measured distance of Vega, this corresponded to an actual radius of 80 astronomical units ( AU ), where an AU is the average radius of the Earth's orbit around the Sun.

At high latitudes ( near the Earth's poles ), they are very low, making communication difficult or impossible due to factors such as atmospheric refraction, Earth's thermal emission, line-of-sight obstructions, and signal reflections from the ground or nearby structures.

At that point in Earth's history these rocks made up the soft bottom sediments of a large, shallow ocean, which stretched across much of North America.

At the Earth's surface, earthquakes manifest themselves by vibration, shaking and sometimes displacement of the ground.

At Limoges, he is found with Mars and at Astorga with Serapis, Isis, Mars-Sagatus and Core.

Similar to the Mole from Thunderbirds, it is named after the underground world from Edgar Rice Burroughs's At the Earth's Core.

At the discretion of the Mouse Subcommittee, Core G also occasionally evaluates mouse lines provided by investigators.

At the spring 2007 IDF exhibition Intel Corp. demoed Q4RT, a raytraced version of Quake4, running on a blade server composed of four Core 2 Quad based machines.

They first appeared in the 1968 short story Grendel, but were already mentioned in the 1966 short story At the Core.

In the short story " At the Core ", Beowulf Shaeffer, who made the discovery about tidal forces five years previously, in " Neutron Star ", discovers that the Galactic Core is exploding.

At this time, the Foundation held a large portion of the periphery in economic control and word of the Foundation was beginning to reach the Empire at the Galactic Core.

Crashlander brings together the short stories featuring the space pilot Beowulf Shaeffer — " Neutron Star " ( 1966 ), " At the Core " ( 1966 ), " Flatlander " ( 1967 ), " Grendel " ( 1968 ), " The Borderland of Sol " ( 1975 ), and " Procrustes " ( 1993 ).

Neutron Star, At The Core, Flatlander, and Grendel were previously included in the 1968 collection Neutron Star.

* At the Earth's Core ( 1976 )

At first Sanakan is an antagonist ; later in the story, she is given a new mission to protect Cibo and the Core.

At the Earth's Core may refer to:

* At the Earth's Core ( novel ) ( 1914 ), by Edgar Rice Burroughs

* At the Earth's Core ( film ) ( 1976 )

For instance, two stories in the Crashlander short-story anthology consider separately the implications of a super-fast hyperdrive (" At the Core ") and medical nanotechnology (" Procrustes ").

The Long Shot — the ship flown to the galactic core by Beowulf Shaeffer in the short story At the Core and flown to the Pierson's Puppeteers ' fleet of worlds by Louis Wu, Speaker to Animals, Teela Brown, and Nessus in Ringworld — is built inside a # 4 General Products hull, most of which is filled with the advanced " quantum II " hyperdrive leaving only a small two-chamber living area.

At the heart of the York College campus is the Academic Core, which houses classrooms, lecture halls, laboratories, art studios, the library, computer facilities, academic and administrative offices, as well as dining facilities and a bookstore.

Critic William Fulwiler argues that Edgar Rice Burroughs ' At the Earth's Core was one of Lovecraft's primary inspirations for " The Nameless City ", citing " the reptile race, the tunnel to the interior of the earth, and the ' hidden world of eternal day '" as elements common to both tales.
