However, there are other, more serious causes of floaters, including infection, inflammation (uveitis), hemorrhaging, retinal tears, and injury to the eye. Floaters are more likely to develop as we age and are more common in people who are very nearsighted, have diabetes, or who have had a cataract operation.
Quick Answer. One cubic meter of soil weighs between 1.2 and 1.7 metric tonnes, or between 1,200 and 1,700 kilograms. These metric figures convert to between 2,645 and 3,747 pounds, or between 2.6 tons and 3.7 tons, per cubic meter. Loose topsoil is lighter, and compacted topsoil is heavier.
The texture of soil is determined by the ratio of sand, clay, and silt in soil. Soil with higher sand is sandy loam and feels more grainy because sand grains are larger than than the other rocks grains. Silty loam is produced by a higher percentage of silt in the soil. It is a finer grained soil because silt tends to be smaller than sand. On the soil triangle, these three components are able to make up a wide variety of soil textures. Soil is named for its texture, thus the texture of a soil is very important. Too much or too little of any of these components can make the soil not usable for agriculture.
