These were due to an enormous amount of exceedingly fine dust blown to a great height by the volcano's explosion, and then globally diffused by the high atmospheric currents.

These events would have released massive amounts of dust and ash into the atmosphere, reducing surface sunlight, hindering photosynthesis, and severely disrupting Earth's biosphere.

These include emissions of airborne pollution in the form of dust, gases, noise and vibration when operating machinery and during blasting in quarries, and damage to countryside from quarrying.

These dust lanes have caused astronomers to discern that it recently merged with a small spiral galaxy.

These roads have the same base layer as gravel roads but are covered with a thin layer of bitumen to reduce maintenance cost and dust formation.

These much wider disks were found to be circular and free of clumps, with dust particles ranging from 1 – 50 μm in size.

These observations supported a number of longstanding hypotheses about comet construction, particularly Fred Whipple's " dirty snowball " model, which correctly predicted that Halley would be composed of a mixture of volatile ices – such as water, carbon dioxide and ammonia – and dust.

These volumes were advertised as being written by the author of Nancy Drew, and were promoted heavily on dust jackets for this series.

These layers may have been formed by deceleration due to radiation pressure as the dust has moved towards the stars.

These immense dust storms — given names such as " black blizzards " and " black rollers "— often reduced visibility to a few feet ( a meter or less ).

These symbiotic binary systems are composed of a red giant and a hot blue star enveloped in a cloud of gas and dust.

These include sunning themselves, dust bathing and water bathing.

These other eruptions had already built up a substantial amount of atmospheric dust.

These result because the diamond dust crystals form directly as simple hexagonal ice crystals — as opposed to freezing drops — and because they generally form slowly.

These clumps of dust could be explained by gravitational interaction with a planet orbiting just inside the ring of dust.

The center of our galaxy also shines brightly in the far-infrared: These emissions are from dust in circumstellar shells around numerous old red giant stars.

These stars heat up the dust and cause it to glow brightly in the infrared.

These objects can be seen with minimal obscuration from dust because the constellation is not in the direction of the galactic plane.

These winds are likely to be driven by radiation pressure on dust condensing in the upper atmosphere of the stars.

These effects can sometimes cause a slight loss of sharpness in the scanned image when Digital ICE or a similar infrared channel dust removal function is used.

These screens should be vacuumed or washed to remove dust.

These include dust from solid rocket motors, surface degradation products such as paint flakes, and coolant released by RORSAT nuclear powered satellites.

These trails became primitive roads which were eventually paved.

These trails are designed exclusively for foot traffic and cyclists, and now pass through many communities, beginning at the downtown core and extending into areas such as Langford and Central and North Saanich.

These mogul trails are generally relatively steep.

These exotic plants thrive by utilizing manmade structures such as roads and trails.

Water vapor Condensation trails | contrails left by high-altitude jet airliner s. These may contribute to cirrus cloud formation.

These trails and roadways gradually evolved into U. S. Route 11.

These trails are known as the Western or Great Western trails.

These trails were later used by the fur traders and settlers, and were known as the " ox cart trails.

These hiking and biking trails run through the county:

These trails do not have clear tracks ; in many cases there are only occasional markers in the natural forest and it is inadvisable to use them without the company of an experienced bushwalker who knows the area.

These Spanish scouts blazed a number of trails in the area, including the Anza Trail, which runs through the Edgemont area of present-day Moreno Valley.

These locations include lighted sports fields, winding trails, playgrounds and beautiful picnic space.

These trails soon become roads and with roads, railroads came as well.

These include neighborhood and community parks, athletic fields, playgrounds, greenways, trails, tennis courts, skating rinks, picnic areas, conservation areas, nature areas, several public fishing areas, swimming beaches, and the City's Central Maintenance Facility, Senior Center, and the Lakeville Area Arts Center.

These trails were used by early settlers and freight companies, and helped to establish where the community of Twin Bridges would develop.

These trails are known as the Western or Great Western trails.

These include the Trailhead to the North which is a starting point for many different hiking trails. The Sonju hiking trail is a great way to view the North Shore during the Summer months.

These areas include lakes, rivers, and expansive ranges of mountains, covered with trees and wildlife and hiking trails, including Farny State Park, Wildcat Ridge WMA, and Mount Hope Historical Park and Splitrock Reservoir.

These facilities provide a wide range of activities from walking trails to tennis courts.

These plans will help the town grow in a meaningful way and provide more sidewalks and trails along with an overall plan for better roads and transportation.

These trails are located on private land but access is unrestricted.

These observations led the astronomer to formulate the hypothesis, subsequently proved to be very exact, that the meteor showers could be the trails of comets.
