"A pair of scissors consists of two pivoted blades. In lower-quality scissors, the cutting edges are not particularly sharp; it is primarily the shearing<span> action between the two blades that cuts the material. In high-quality scissors, the blades can be both extremely sharp, and tension sprung - to increase the cutting and shearing tension only at the exact point where the blades meet. The hand movement (pushing with the thumb, pulling with the fingers) can add to this tension. An ideal example is in high-quality tailor's scissors or shears, which need to be able to perfectly cut (and not simply tear apart) delicate clothes such as chiffon and silk."</span>
Mountain building, weathering, and erosion eventually expose the fossil at the surface. Sedimentary rock is the type of rock that is made of hardened sediment. Most fossils form from animals or plants that once lived in or near quiet water such as swamps, lakes, or shallow seas where sediments build up.
The landforms in the interior of the continents and at their margins mostly differ because of the difference in geological activity.
Explanation:
The landforms that are found in the interior of the continents tend to be old. They also are mostly consisted of sedimentary and metamorphic rocks. In general the erosion is much more evident and dominant, thus the landforms also are with lower elevations when compared with the ones on the edges. This is due to the lack of geological activity as the interiors of the continents tend to be far away from the plate boundaries.
The landforms on the edges of the continents tend to be younger in general. The reason for that are the subduction zones and intense geological activity. The intense geological activity is due to the close proximity of the plate boundaries. The landforms tend to be higher in general, and volcanic arcs are also a common sight.
