Ocean Floor Appears: This out¬ward movement could push continental blocks apart or push previous ocean Floor rocks be¬neath the continents, which would explain the comparatively young age of the rocks on the ocean floor. In the Pacific Ocean, for example, the new ocean Floor seems to spread outward from a great ridge known as the East Pacific Rise. As the new Floor moves outward, the older seabed ahead of it should be forced downward into the deep trenches that ring the Pacific Ocean.
As one writer put it, the ocean Floor appears to act as an enormous magnetic tape on which changes of the earth's magnetic field are recorded. We can play back this tape by mov¬ing magnetometers across it. Heirtzler, Dickson, Herron, Pitman, and LePichon of Lament have extended this study of sea-floor spreading both geographically and in time. In a series of publi¬cations in March 1968 they amassed an impresbody of consistent data that appears efutable.See Also Clean The Floor And Fill:If the Floor is uneven, it is best to use screeding compound to level it. You can buy this either as a powder that you mix with water, or ready-mixed in a tub.
Clean the Floor and fill the Floor thoroughly, then use a little of the compound to fill any holes and cracks. Allow these repairs to set before -you apply the screeding compound over the whole area. Simply pour the compound out on to the floor, brush or trowel out, and leave it to find its own level.
After gnawing teeth are in use, place pet in large animal cage (see Part IV). Reproduce forest Floor as closely as possible: Fill cage with 12-14 inches of Clean the Floor and fill, moist soil, preferably mixed with leaf mold; moisten soil from time to time; change once a year; put piece of old tree stump against one side of cage for pet to sprawl on; scatter 2-3 flat rocks about for it to dig under, as well as old bark and layers of dead pine needles and dry leaves. Provide bunches of Clean the Floor and fill, dry grass, sweet hay, old furniture stuffings such as Clean the Floor and fill kapok for nesting, but do not use cotton.
On The Other Hand See Synthetic Floor Coverings
Among:Synthetic Floor Coverings
Among the Floor coverings made from combinations of synthetic ma¬terials may be mentioned vinyl, linoleum, rubber, cork, and asphalt tile. Vinyl is a plastic used extensively for Floor tiles. It has a hard, slightly resilient surface and is reasonably resistant to denting, scratches, grease and acid stains. It is very suitable to heavy wear and particularly in kitchens and other service portions of a house. It is manufactured in variously dimensioned square and rectangular Tile sizes of %th and l/12th inches in thickness, and in many colors, marbleized and wood-grained effects. It can be laid in patterns of contrasting shapes and colors and is often alternated with ceramic tiles or brass strips. It is also used as a binder in making tiles of cork, asphalt and asbestos.
Selection and Laying oŁ Rugs and Carpets
In nearly all rooms of the house, with the possible exception of en¬trance halls and sunporches, it is preferable to cover the Floor with rugs, carpets, or other forms of covering. Floor coverings add warmth, dull the noise of footsteps, help silence any possible echo, and by their pattern, weave, or color, make an important contribution to the general scheme of decoration. Floor coverings should generally be considered as backgrounds for the furniture, and although patterned materials may be used, these should never be obtrusive. Strong color contrasts between pattern and field are psychologically uncomfortable to tread upon, and as a general rule plain-colored Floor coverings should be subdued in tone. The Floor covering, whether patterned or plain, should always have its color or colors re¬peated elsewhere in the room. A Floor covering that is in a colored pattern usually will not permit the use of other important colored patterns on the Wall or larger pieces of upholstered furniture. Plain Rugs and carpets have been woven only since about 1900 and they have consistently grown in popularity since that date. Texture mottling, pepper and salt effects made by twisting different colored threads in the pile, and patterns produced by contrasting pile heights have served to give them surface interest.
