It was discovered early in the 20th century that trees of the same species in the same region displayed remarkably similar ring patterns across the tree trunk and in the end grain of timber beams. Each year a tree gains another ring as it grows; the thickness of which depends on the amount of growth. In a year with ideal growing conditions, trees will produce a wider ring than in a year with poor conditions, and all the trees in the same region are likely to display the same general chronological growth pattern, despite any local ecological variations.
Unlike humans, whales can stay underwater for long in fact they sleep near the surface semi-consciously so as to reach the surface to breath when required quickly. Whales and human beings both are mammals but they are differ from each other due to their different features i.
Known as voluntary breathers, whales sleep in a partially conscious manner as their one hemisphere of brain sleeps at a time to avoid drowning in the water, though they are just like humans in many ways, but live in distinct atmosphere. Whales are mammals are similar with human being such as it,can stay longtime in underwater with out oxygen because it contains special respiratory system,and it will be conscious;mostly it lay by near surface.
Whales are different from humans by the environments in which they live and their breathing system since whales stay underwater but have to come out to the surface to breath and can hold breath for several minutes which makes it a voluntary breather and while they rest, only one hemisphere of their brain sleeps and remain partially conscious in fear of getting drawn.
Rings in the tree trunk can provide provide information on their growth patterns and species which could be used to analyse when the timber was felled.
Whales are mammal as similar as humans; however, the most crucial difference is that whales not only have special respiratory system that allow them to breath oxygen under water, but also can sleep under water by remaining partially conscious without drowning. Whales are mammals like a man but have extra ability to sustain underwater without taking oxygen for a long time and they sleep half conscious near sea surface to avoid drowning.
Whales are quite similar to other mammels such as human beings, but differ with respect to breathing and sleeping mechanisms. The appeal of dendrochoronology as a dating tool is objective and entirely independent of other evidence and the results are accurate and reliabe. Dendrochronology, a dating tool is based on the discovery that timbers from same species and same region develop a ring pattern across the tree trunk every year, which helps to accurately identify the year when the tree was felled, by comparing the tree rings of historic timber against the documented master chronology.
Dendrochronology or tree ring dating is the scientific method of dating based on the analysis of patterns of tree rings, also known as growth rings. Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year. This has three main areas of application: paleoecology, where it is used to determine [ ]. Here's how tree ring dating, known to scientists as dendrochronology (from the Greek roots Dendron = tree, and chronos = time), works. If you cut a tree down today, it's straightforward to count the rings inwards, starting from the tree's outside (corresponding to this year's growth ring), and thereby to state that the th ring from the outermost one towards the centre was laid . Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology is useful for determining the precise age of samples, .
Whales are like human just a one difference that they cannot sleep for a long time because if they become unconscious for a long they may drown, so they choose surface to come up for air easily.
Whale a distinct mammal that live in ocean and breathe outside, its sub-consciousness mind do not let it drown while sleeping and breathe when required by being near the surface of the water.
Whales are mammals like human, but an important difference is that they can stay underwater for longer period without breathing and even when they sleep, one hemisphere of their brain is conscious so that they do not get drawn and while sleeping remain near water surface so that, they can easily come to the surface to breathe through the blowholes on top of their heads.
Dendrochronology tree dating technique discovered in the 20th century reveals the timber felled year by trunk ring pattern, tree ring data are documented across country by laboratories and analysis results are reliable and accurate.
The Whales are in many ways like humans but they are distinct paramount in terms of; the environment they live in, a bizarre respiratory system and astounding way of partially conscious sleeping. Ring patterns in tree trunks shows equivalence in trees of same species in a particular region and is used as a dating tool dendrochronology due to its high precision. Whales are mammals, yet they are different from humans in terms of living environments and breathing system which helps them to stay underwater for a long period without breathing, and also due to respiratory system they cannot sleep in unconscious condition due to which they have to be in consciousness during the sleep as well.
Dendrochronology or tree ring dating is most useful technique to see the amount of growth in tree because each year additional ring develops in the trunk and which can be also noticed from the timber felled, moreover, this technique is completely reliable for analysis of tree.
Dendrochronology as a tree dating system is an objective method of identifying the time of the year when the trees used in the building were cut down that provides trustworthy and exact report of the age of the buildings.
Whales are mammals like us,but have unique features in their own way,they can breathe at their own will,whales never sleep fully so that they can breathe intermittently and avoid drowning. Dendrochronology or tree dating is the science which gives us important details about age of tree and buildings in which they are used,this knowledge of tree age with proper historical data of various tree species provides insights into aged building and structures.
Dendrochronology is the dating and study of annual rings in trees. The word comes from these roots: ology = the study of. chronos = time; more specifically, events and processes in the past. dendros = using trees; more specifically, the growth rings of trees.

Whales are similar to Human beings because they also need to breathe and sleep, however since they live in a different environment from us, they do these things differently from us. Whales are mammal as similar as humans ,being the most crucial difference is that humans and whales live in different environments and whales have a special respiratory system that enables them to stay underwater for several minutes without breathing oxygen.
The dendrochronology as a dating tool is that it is objective and entirely independent of other evidence such as datable design features and documented information, where analysis results in a clear match with the master chronology the outcomes are completely trustworthy and correct.
Tree ring data helps in reveling the history of the building based on when timber is cut, tree ring data is documented for most of regions across the country over the hundreds of years out of which oak has best documented evidence since its widely used in the construction, however if the results of dating tool and analysis match is highly regarded as accurate.

Even human beings and whales both are specified under mammal category,they have different living environment and different way of respiration and sleeping habits. Save my name, email, and website in this browser for the next time I comment.

Each record is valid for a geographic area whose extent depends on local weather patterns, because weather and hence tree growth patterns vary with location. A bonus of dendrochronology is that the width and substructure of each ring reflects the amount of rain and the season at which the rain fell during that particular year.
Thus, tree ring studies also allow one to reconstruct the past climate, e. Total Word Count: 0.
