Among the three major types of rock, fossils are most commonly found in sedimentary rock. Unlike most igneous and metamorphic rocks, sedimentary rocks form at temperatures and pressures that do not destroy fossil remnants.ost sedimentary rocks contain either quartz (especially siliciclastic rocks) or calcite (especially carbonate rocks). In contrast to igneous and metamorphic rocks, a sedimentary rock usually contains very few different major minerals.
How many tons for a 1500 sq ft home. I have been getting bids for an ac unit in my home and I have been getting a range of 3 tons to 3.5 tons. I live in Dallas Texas and my home is pretty well shaded during the days and the majority of my windows face north or south.
Best Answer: A short ton which is what we usually use in the US is 2000 pounds. A long ton is 2240 pounds (used in the UK). In addition, there is a metric ton which is 1000kg or 2204 pounds (about). In much of the world this is called a tonne, but in the US, it is usually called a metric ton.. The short/long is because of the different definitions in the US and UK for hundredweight. In the US a hundredweight is 100 pounds, but in the UK it is 112.
