Click on each eon of Earth's Unknown
history microscopic
on the timeline above to view the microscopic
dominant lifeforms, then macroscopic
characterize
what you see.
In this lesson, you'll explore the The PETM was the last rapid warming
changes that took place during the event on
PETM. Why do you think exploring Earth. By exploring what happened then,
these changes is important for we can
understanding the effects of get an idea about what can happen to our
climate Earth
change today? today if it continues to get warmer.
Look at the world of the 75% the same
Paleocene-
Eocene. How similar would you
say it
is to today's world?
, What is the general surface Increasing
temperature trend from the late
Paleocene (~59 million years ago)
to
the early Eocene (~51 million
years
ago)?
What was the average global 23°C
surface
temperature at 59 million years
ago
(round to the nearest degree)?
What was the average global 28°C
surface
temperature at 51 million years
ago
(round to the nearest degree)?
What was the rate of temperature 0.00005°C/century
change during this period in time?
To
find the rate, divide the
temperature
change by 8 million years, then
multiply by 100. Enter your
number as
a decimal.
What was the average deep sea 8°C
temperature before the PETM
(round
to the nearest degree)?
