All the answers
You are looking at a tree ring. What does the wide ring represent?
a drought( little to no rain)
a rainy and warm climate
snow
You are looking at a tree ring. What does the thin ring tell you?
that in this year there was a drought
that in this year there was a lot of rain
that in this year the tree grew 10 feet
A cross-section of a tree shows 25 rings, all of which are about the same size. Except for the 15th and 22nd ring which are twice as thick as the other rings.
What does this finding tell you about the tree?
During these two years, the tree lost all its leaves and branches.
The two thick rings protected the tree from cold weather.
During these two years, the tree grew much more than the other years.
The tree did not receive much rain during years 15 and 22.
A cross section of a tree has 65 rings. All of the rings are about the same size except for rings 22, 23, 24, 25, and 26. These 5 rings are half the size of the other rings. What does this tell you about the climate during those years?
During these 5 years it was very wet and rainy.
During these five years there was a drought(no rain)
During these 5 years the tree grew more than at any other time.
What information can we learn from ice cores?
We can learn how the climate has changed.
We can learn how the dinosaurs died
We can learn about droughts
Ice cores...
show the layers of volcanic ash that has occurred throughout time
show the layers of the oceans and their changes over time
show the tree rings and their growth over time
show the layers of snow and ice that have built up over thousands of year
Can cause missing information in rock layers.

Unconformities
Law of Superposition
Ice cores
This preserves much of the organism, including the organs and genetic material. It occurs when an organism becomes trapped, dies and is quickly frozen.

Why do intrusions and extrusions of igneous rock not have any fossils in them?
The high temperature of the magma destroyed any remains of organisms.
The rock is too hard.
The rock is too young.
Why not?
