Studying Natural Climate Change

1. Tree rings

   • A tree ring is each of a number of rings in the of a tree trunk, representing a single year's growth.
   • Movement of Continents
     • Movement of continents describes one of the earliest ways geologists thought continents moved over time.
       • ¿how tree rings let me know about movements of continents?
         • Tree rings show us about the movements of continents by the tree at areas.The tree rings would give scientists some information about that area’s local movements of continents in the past. The trees and environmental areas had change in the different ecosystems that would make them analyze the tree rings.
   • Ice Ages
     • Ice ages are periods when ice sheets and glaciers expand across the planet.
       • ¿how tree rings let me know about Ice Ages?
         • Tree rings show us about the ice ages, the tree rings had a short distance of the rings during their first years, while the tree is old have an expansion in their rings, this would show the periods when the tree was growing it start to expand in the form and even from the place was plot from the first time. The tree rings expand during the years and would give scientists some information about that area’s local expand and the marks of the trees froths era left in the past.
   • Volcanic Activity
     • Volcanic activity occurs when molten rock, ash and steam pour through a vent in the earth's crust.
       • ¿how tree rings let me know about Volcanic activity?
         • Tree rings show us about the volcanic activity, a ring from the tree that have a scar from a forest fire this means,the past year the tree has suffered by any volcanic activity, the tree scar would give scientists some information about that area’s local climate in the past.
   • Solar Energy
     • Solar energy is the radiant energy emitted by the sun.
       • ¿how tree rings let me know about Solar energy?
         • Tree ring show us about solar energy, the stations and how looks the tree we could infer how much solar energy did the tree had received as the light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring plus one dark ring equals one year of the tree’s life. The tree rings would give scientists some information about that area’s local solar energy in the past, scientists look on the tree rings are if they have a change as dark or light colors on the rings, the size if is tall or still in a small size by the time.
   • The tree rings can not find enough information even having trees from oder periods and the ones from this years is not enough to show them a extensive data about the movements of continents that had past through years.
