Fossils A fossil is the prehistoric remains of a plant or an animal. Fossils are usually are kept at their best when they are buried under many layers of sand and mud. Under the great pressure from the ground‚ the sand and the mud become sedimentary rock. The minerals combine forming a mould of the plant or animal under the ground. A fossil can be a trace fossil or a body fossil. A body fossil is what actual organic material from a creature or plant (like a bone). Trace fossils are signs of

water that the mud turned to ’slime’‚ so we can imagine just how dirty the trenches are‚ with a thick slime forever flowing around them. The word ’guttering’ also helps make the metaphor effective as it emphasises the quantity and noise of the water. Alliteration is also used in the poem to emphasise the conditions of the trenches. "Choked the steps too thick with clay to climb"‚ is a line where the repetition of the harsh c/k sound imitates the squelching of the soldiers boots in the mud‚ but also helps

one way to bond with your horse. Having a connection with your horse always makes it more enjoyable and it helps you compete better.

For my horse I personally use a rubber curry comb which is good for getting

the experiment are: 1. To demonstrate pump performance when connected in series and parallel 2. To show shut off point of pump in series and parallel ABSTRACT / INTRODUCTION Pump is a general term for any fluid machine; used to transfer and add energy to fluid in a system‚ either at the same level or to a new height. There are some fundamental parameters used to determine the performance of a pump. The mass flow rate of fluid is the obvious primary pump performance parameter and for incompressible

process generates two types of wastes – drilling fluids and &ii cuttings. Drilling fluids (or muds) are used to aid the drilling process. Muds are circulated through the drii bit to lubricate the bit and to aid in carrying the groundup rock particles (drill cuttings) to the surface‚ where the muds and cuttings are separated by mechanical means. Most onshore wells are drilled with water-based or oil-based muds‚ while
