The thicker the tree ring the more tropical climate they lived in. The thinner the tree ring the colder and drier the climate was. 80,000,000 years ago tropical trees lived in Greenland. This tells us that Greenland was a tropical island 80,000,000 years ago.
The rings in a tree trunk are used to work out how old the tree is. There is a ring for each year the tree has lived so by counting the number of rings you can work out how many years the tree lived for. You can also roughly determine the weather in those years based on the thickness of the rings, more water and nutrients makes thicker rings and drier years result in thinner rings.
Each ring represents a year of the tree's lifetime e.g. if a tree has 12 rings it is approximately 12 years old.
Tree rings tell you how old a tree is. As a living tree produces a new layer each year, one can measure the tree's age by counting the rings.
Ice cores with O16 and O18 water molecule isotopic compositions help in determining snow accumulations and past temperatures. Tree rings show difficult growing weather with narrow rings and prosperous growing weather with wide rings. The coarse and fine clay or silt in sediments show snowfall, rainfall, and temperature evidence.

In these rings itself the vascular tissue, specially the xylem is gathered in a tree. The phloem remain peripheral to these rings.
Trees tend to grow faster during warmer and wetter years, and this is reflected in the tree rings. Scientists can look back through the centuries using tree rings, and identify which years were warmer. If there is a warming or cooling phase, the rate of change and its duration can be identified readily from adjacent tree rings. With the help of this process, they have been able to show that the current global warming phase represents the fastest increase in average temperatures for several thousand years.
The climate above the tree line is called the alpine climate, or the tundra.
Tree rings or annual rings tell how old the tree is.
They give how old the tree is. Like if the tree has 800 rings, it is 800 years old. how many rings determine how old the tree is.
Palms do not show growth rings.
You can tell a lot of things by looking at the rings of a tree. Rings of a consistent with throughout indicate the same climate each year but narrower rings indicate drought or a severe winter.
The rings in tree show how old it is. Each year, a tree will create a new layer of bark around its old one.
due to the climate if its sunny or rainny climate.

Ice cores with O16 and O18 water molecule isotopic compositions help in determining snow accumulations and past temperatures. Tree rings show difficult growing weather with narrow rings and prosperous growing weather with wide rings. The coarse and fine clay or silt in sediments show snowfall, rainfall, and temperature evidence.
A tree ring reflects the type of season during that time in the life of the tree. Uneven rings show a mixed weather type of year.
Ice Cores shows the layers of snow it tell about atmosphere... The Tree show it age in tree rings and shows dryness mostly about the weather...
By examining tree rings and ice core samples, climatologists are able to determine the environmental and climate situation prevalent at the time the tree was growing and when the water froze.
