Question

Dendrochronology is:

• A. The method of scientific dating based on the analysis of tree-ring growth patterns.
• B. A core sample from the accumulation of snow and ice over many years that have re-crystallized and have trapped air bubbles from previous time periods.
• C. The study of glaciers or more generally ice and natural phenomena that involve ice.
• D. The scientific study of landforms and the processes that shape them.

Hint:

Split the word into "dendro" (tree) and "chronology" (dating by time).

Answer 1

The Correct Option is A

Step 1: Break down the word "dendrochronology".
"Dendro" refers to trees and "chronology" refers to the order of time or dating, so the word itself points to dating something using trees.

Step 2: Recall what part of a tree records time.
A tree grows one visible ring each year, and the width and pattern of these rings change with the weather each year, so counting and studying these rings gives a year by year record.

Step 3: Eliminate the other options.
Option B describes an ice core, which is used in glaciology, not tree studies. Option C describes glaciology directly, the study of ice, which is unrelated to trees. Option D describes geomorphology, the study of landforms, again with no link to tree rings.

Final Answer:
Dendrochronology is the method of dating based on studying tree-ring growth patterns. \[ \boxed{\text{Tree-ring dating method}} \]
