invitation
in the opportunity to talk about a
crater and the state pact made
in the yucatan peninsula and that is
part of a select group of structures
geological public had been heard
talk treated me very well although this
Friday
the alleged participants
[Music]
in the 90 minutes
let’s analyze what it is that makes
interesting because it is important
study of the skull
we love that impact of ash in
the surface the solid bodies in the
solar system
what we observe on the moon are
impact craters of different
sizes and shapes the same as well as by
the impact of a body the size of
mars collided with the earth information and
from that impact our
earth system the moon preserves the
record the impacts in those stages
early evolution of the solar system
studying the impact craters
we can learn about the evolution of
regulatory supervision
heat the satellites
Our system is inform in the country
depending on what you will say the moon
we can observe areas that have a
high density of tastings and are those
they have less in the stands and in this
we can determine mega clear what happens
when we get older we have the
traces of the passage of good years
moments in the most experience in
screen
also do not know the areas that have a
high density of character are more
oldest in the area next have
less large studios we can also
make similar geological maps to
that we have here on earth and we can
determine the sequence of inventions
that in this area of kraten keys in the
moon that is easy to beat me quattro cup
after approving first same after no
It is small they are in the
edge of the large area were formed a
once it was already formed by paco
and if we could see more details
we had the material and fragmented into
who knows the impact at the moment
like when we have a stone on
sand we raised by ccoo
if we throw stones we are going to make several
layers of sand and that we can not also
observe in the cloud and it’s not us
the ports
we can also learn about the
inside of the six bodies in on the
rest
about the physical properties the
composition of the cortex
this is the face of the moon that we do not see
and if they remember previous is different
The large instruction are
different we do not have those are the rules
of rabbit shape on the moon
one possibility is that for some reason
He is not going to do today than five or six
metal cores I decided to impact the face
that we do not see a different way to the
that they
this however is difficult to evaluate
the impacts occur in all
directions and both sides are
subject to the same type of impacts
then another possibility is that this
depends more on the properties of the
cuts so that when we negotiate with the
same object
also the force on the floor and some
of the screens here is being used in
boat will clearly also do
we have for example a good way the
Gaddafi a thicker way and the
hit the effects and by how they
transmits see this is eta
walk with the moon studies show
that the bark of the lake that we see is more
thin on the bark on the side that does not
we see it’s almost in the tone of this draw and
the core of the moon is displaced
towards the earth
this explains why the discussion that
transcends not occur the police
different
however despite a series of
additional questions that is why not
wants to be displaced
we have these differences in the cortex
is it
always the research is one thinks
who found a question about the
answer and what we are doing is
find a new one with the new law the
six impacts on the process that as
to the planets
the asteroids to all the bodies or
as it is called
it forms
[Music]
this is being
form a main campus
piece of the five concerts you assume
trainers
talking about the size of planets and in
those planets also touched like
what happened to the earth a jacket to
the moon
we have more than 50 athletes and now
we have this vote
most of the planets was
destroyed in these under these conditions
and earth
unlike what happens in the
surfaces of the other bodies
we have very few impact craters
very small number of 180 have been
documented and of them we only have three
of these large farms and adults
greater than 180 kilometers of origin
Chinese always from France reported does
two million years and they are very
modified
the former French conservative leader and the
Chinese contrast it formed ago
less time
66 million
let’s see in Catalan is the best place if
I would have touched because it starts with the
impact
[Music]
[Music]
choose
[Music]
I do not know
the power
however soccer
effective of which more than 3 in both
oceans the climate and the capacity of
life support systems in the
planet in the impact it generates
very high temperatures
plus five old members who
these heights uncomfortable and and the impact on
a few seconds
the center paragraphs these effects are the
that have the ability to affect not
I know the organisms and that’s what
that I started my interest to study
read what happened through a particular group of
organisms to dinosaurs that lived
employment in more than 160 170 million
years in and massify most of
the 30 equipment and systems in currents
then absolutely disappeared
these possible commissions will begin to
get on your knees to explain why
Hot suddenly disappeared
among them on climate change
volcanic even nurses and when
there was evidence of this impact and
that form treats of cello found the
way to study in the cells
its functions with other students
van halen 90 76 percent of the
species
three out of four times in oceans and
continents is extinguished
we do not know is the last mass extinction
that we have a registration record for
study mass extinctions is
also important to be able to understand
that we are causing cuts or the
organic eagle increasing number of
species are disappearing understand
the causes and how the
ecosystems is now part of our
interest is that already of this event that
he spent so much time studying
and also because some agencies
and programs about what happened next
for diversification
we have that are fear the impact is
marked in red with a thin layer of
clay
a few centimeters at 1,000 meters
has the figure of the lower part we can
see
these examples in the bottom
are in the segments of the time of
the dinosaurs on the top
is not use the segment from the time of
the six magistrates and stake for the
we can find in different parts
of the world c is the only one that has a
global distribution nor the campaign we saw
for the abundance of elements that are
rich I do not know what I’m going to say the comets
and very poor in the earth’s crust that
are the luxury items known as
plan e
study these sequences we also
allows you to see how much the sheet recovers
it took life to think of the different
places that happened at the impact site
in the area of the Gulf of Mexico and the
Caribbean
the largest thick ice layer
investment of 102 centimeters to 1,000
meters and at the bottom and the part
superior to oneself than the others
layers in other places a layer of
spherules ready from a layer of clay
that we mark the differences in a bar
in the middle we have a layer of sand
high energy concept is written down
they are from kitchen tsunamis bigger than
we have in the geological record and that
layer marked by the sales area that
has evidence of having achieved
temperatures of
hundreds of members the voice of god is
known as the fireball
this is another record in the part of
Atlantic ocean in the pair with faith not
we have in sediments from the time of the
dinosaurs at the top we have
Sediments of the Mammalian Age
and the medium what we have is what
happened to cause material destruction
for the Chinese market and a layer that
known as in the empty oceans that
have attracted a lot of attention because it is
difficult to find segments of more
deep that they do not have remains of
conchitas organisms and in this stage
is directly on the layer of
the temperature of the fireball the
evidence that we have in this type of
records strongly supports a relationship
cause between the impact and
institutions
we also have other questions
among them those of the tenth 10 to 15
minutes is like it’s a topic that
come back that we just saw until the
time no person fell with
a small impact in relation to size
of the planet
how is it possible to impact these
dimensions have this global effect
we can give us an idea of another potpourri
of this numerical simulation of the ce
it is 2.5 seconds fifteen seconds
thirty seconds to have time to
have only 12 seconds
the body has reached a temperature
of 2 degrees the policy was studied the
shock wave
in a forum with a second makes a glance
the name of ten names for when
we have five seconds
the hole already has 25 kilometers and the
most of the material is
sensitized out of gravity
land
for when we have half a minute the
continuous laterals of the material and
mental although the air the temperature is
the 10 matches in thousands of kilometers
outside the prat and that’s what causes
an impact of these dimensions
the other reason that are the
characteristics of the place that does not
I was thinking about that moment of choosing the place
ideal for that position despite being
voted on about three kilometers
of sulfur calcium carbonate and these
they have the possibility of generating gases
broken voice global warming and
sulfur compounds and causes changes
in twelve oceans savings in others
studies we have also gone from
study the organisms and mechanisms
take down the different groups and
also see under what conditions
some surviving organs had
shown delighted
the poster is covered by about 90
miles of rocks and if we’re going to comply
unfortunately we are not going to see which one
is the weight that you join these movies
public
however, thanks to that, it is very good
preserved it has left
I have not taken a sample to do
laboratory analysis
it turns out that we have to do and that
is what is happening to us for several
years
these studies do not re – comment a
part of the system the planetary system
among them it studies the characteristics
of the impact craters between them
this is known as the ring of
peaks is a fact and it is difficult to form
circular mountain chains we can
take to win more global or in
form of alcohol like the Himalayas
you know how hard to form chains
circular then part of our
interest to study how a
circular chain and these chains are the
free of charge and for this we did not
and
the part of the sea and the marine area in 3d
in Catalan and it is part of the programs and
international innovation throughout
almost 30 years that we have is that the time
before not finding answers to
different questions learn a lot
impact is able to fill these effects
environmental cause remission
however the most interesting afternoon is
the questions that have been generated at
over these years fast investigation
that we have opened
how the materials behave
[Music]
the counselor when I heard
it goes as a lesson to the earth
modifications that are regulated and
is a part has been the most
interesting and beautiful is that these
studies continue and surely
peppers surprises findings more
[Music]
