1.
Which of the following provides the longest record of climate change?
Coral cores
Ocean sediment cores
Ice cores
Tree rings
Using this figure comparing the thickness of the tree ring core sample, determine which statement represents a reasonable conclusion about past precipitation (assuming the tree growth is precipitation limited).
Precipitation was relatively favorable for tree growth during 1983
Precipitation was relatively favorable for tree growth during 1994
Precipitation was relatively unfavorable for tree growth during 2000
Precipitation was relatively favorable for tree growth during 2005
3.
How can we use Corals and Trees as climate archives?
The length of the coral and tree samples tell us about past climate conditions
The annual growth rings tell us exact past climate measurements
The better preserved a sample, the warmer the climate was in the past
The annual growth rings tell us qualitatively about past climate conditions
4.
The 18O of high latitude ice is typically:
Greater than the oceans
Smaller than the oceans
About the same as the oceans
5
When there are large ice sheets on land, 18O values found in deep sea sediment are:
unchanged
larger
smaller
ACoral cores
BOcean sediment cores
CIce cores
DTree rings
2005 1990 2000 1980Explanation / Answer
ANswer 1: Sea sediments
Answer 2: 2005: thichker the tree ring more the rainfall or precipitation conditions.
answer 3: the annual growth tell us the quality about past climate
answer 4:smaller than oceans
this is becasue as the clouds move from low lattitude to high lattitude they become continously depleted in O18 and enriched in O18 so O18/O16=18O will decrease wr.t to oceans
answer 5: very large
during ice age O16 will not come back to ocean it frezze in ice sheets and oceans become depleted in O16 therefore O18/O16 will increase rapidly during ice age.
pleast thumbs if you like the answer.....for any question please ask me again i am happy to help you
