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.
1 The downy woodpecker is the most common backyard woodpecker in North America, and is one of only about two dozen woodpecker species found in the United States. These small woodpeckers with their stubby bills often visit suet feeders or will take black oil sunflower seeds or peanut chunks from other feeders. They will also nest in bird houses, and may use roost boxes in the winter. The most common plumage colors for all woodpeckers are black, white, red and yellow.
