The determination of seawater density, and its variation, is therefore one of the most important tasks in oceanography. How do you think the density of sea water changes with water depth? The density of sea water depends on: temperature T, salinity S and ; pressure P, which increases with water depth. Oceanographers discuss the density of sea water somewhat differently than a chemist or physicist. The values of sea water density, labeled on the diagonal lines in the graph below, do not include the density of fresh water (1 gram per cubic centimeter g/cm 3) or the decimal places.
Woodpeckers eat nuts, berries, termites, grubs, and other bugs that live inside trees. It pecks through the wood of a tree to find the bugs living inside. That is why their beaks are so long... and strong! + 66 others found this useful.
Even the most eager backyard birders may wish they'd never attracted birds when woodpeckers cause damage to their house, deck, chimney or other structures. Fortunately, there are a number of ways to deter woodpeckers and keep them from pecking unwanted holes.o matter how annoying woodpecker pecking may be, some methods to get rid of woodpeckers should never be used. 1  Do not apply sticky or greasy products to the wood the birds are pecking. 2  These products can coat the birds' plumage and can be dangerous or toxic.
