Question

A thick tree ring indicates which of the following

Answer 1

The correct answer is option A, that is, the year was good for growth.

In the regions where the length of the growing season is the restricting element, the thickness of the rings of the tree can suggest that when the growing time was lengthier (at the time of warmer times) and when the growing seasons were shorter (cooler times). The study of the development of the rings of the tree is called dendrochronology.

Answer 2

The correct answer is option A, that is, the year was good for growth.

Further explanation:

The science in which the rings of the trees is studied is known as dendrochronology. The number of rings present in the trunk of the tree determines the age of the tree. Each year an extra layer of cells is added to the trunk of the tree. The thickness of the tree is determined by the climate of the area in which the tree grows.  

During the spring and early summer season, there is quick growth in the bark of the tree which results in the thinner and darker rings in the fall season. During the fall season, there is a prominent slow growth due to which a thicker ring is formed around the trunk.

In the areas and season where the growth of the tree is lengthier, thicker layer of cells can be seen has rings around the trunk of the trees. This occurs mainly in the warmer times of the year. During the cooler times of the year, the season of growth is shorter and does the development of a layer of cells around the trunk is less. This leads to a thin ring.
