The rocks in our planet

Welcome

MY NAME IS CAROLINA ALVAREZ CURRENTLY A STUDENT AT VICTOR VALLEY COLLEGE. I'M 23 YEARS OLD AND MY FALL 2021 GEOLOGY CLASS IS THE MOST INTERESTING CLASS I'LL SHOW THE REASON WHY.

ROCKS ARE EVERYWHERE, OPEN YOUR EYES AND SEE THEM!

I remember when I was in high school, and I was a teachers aid for a geology class. My job was to grade the students work, but as I was in class, I would also get to know the information presented to them by the professor. I would love seeing how there was students who would know the volcanic rocks from left to right. When I decided to take this course, I was excited because it relates to humans and how we serve ourselves from this beautiful planet called earth. Since I was a little girl rocks to me seem so simple but at the same time super intriguing, so far, I know igneous rocks have two different processes, for example we have intrusive and extrusive rocks which they form either by magma or lava. Magma cools down while lava solidifies. I would like to explain more as I get more information in this class. My personal goal for this semester is to fully comprehend the processes, of the geological processes. My goal is to explain or present a topic without hesitating, I would like to know tell the difference between rocks. My realistic goal is to be able to explain to a person who does not know anything about geology, I know a major part of my family does not know what tectonic plates are and as a geology student I feel responsible for learning and growing in this subject so I could help more people understand, this subject often goes unnoticed by many.

SO?

now lets talk about our homes creation i believe we all started from a big bang BOOOM!

THEN THERE IS THIS THEORY THAT EXPLAINS ABOUT THE EXPLOTION WHERE IT ALL STARTED AND WALKED ITS WAY THROUGH WHERE WE ARE NOW, INCLUDING PLANETS AND ALL.

13.8 BILLION YEARS AGO WAS WHEN ALL THIS HAPPENED: THERE IS STILL STUDIES AND RESEARCHS, AND SCIENTIS STUDING IT SINCE IT KEEPS EXPANDING. BACK THEN THE HOT STUFF KEPT EXPANDING THROUGHOUT THE YEARS AND THEN CREATING OUR GALAXY.

IN OUR GALAXY WE HAVE A SOLAR SYSTEM, A START, THE SUN, NINE PLANETS AND EVERYTHING THAT IS BOUNDED TO IT BY GRAVITY. WE ALSO HAVE VENUS, MERCURY, EARTH, URANUS, SATURN, NEPTUNE, JUPITER, MARS, DWARF PLUTO, AND MANY DWARF PLANETS, DOZENS OF MOONS AND MILLIONS OF COMENTS, ASTEROIDS AND METEOROIDS.

THERES IS STILL RESEARCH ON MARS GOING ON TO SEE IF THERES HABITABLE PLANETS LIKE EARTH, WHERE WE LIVE AND NOW LETS FOCUS ON THE INTERIOR AND WHY EVERYTHING HAPPENS.

IN OUR PLANET (EARTH) WE HAVE PLATE TECHTINICS AND WITHOUT THEM WE WOULD NOT BE HERE, BUT HOW RIGHT? HERES IS HOW: SO WE NEED TO FOCUS ON THE INTERIOR TO UNDERSTAND .

THE EARTH DIVIDES IN DIFFERENT SECTIONS :

WE HAVE A CORE, A MANTLE, AND CRUST IN WHICH DIVIDES INTO ITS OWN SECTIONS.

INNER SOLID CORE
OUTTER MOLTEN CORE
LOWER MANTLE
UPPER MANPLE/ TRANSITION
ASTHENOSPHERE
CRUST
TROTOSPHERE
THERMOSPHERE

THE CORE IS PURE MAGMA; OXYGEN, POTASSIUM, SODIUM, IRON, SOLICON, ALUMINUM, CALCIUM... SO THIS MAGMA IS ALSO BEING PULLED OPPOSITE SIDES CREATING THE MAGNETIC FIELD. WHEN THERE IS TOO MUCH PRESSURE THIS MAGMA RELEASES THROUGH PLATE TECTONICS CREATING OPENINGS LIKE VOLCANOES. SO PLATE TECHTONICS ARE RESPONSIBLE FOR EARTHQUAKES, VOLCANOES MOUNTAINS AND ROCKS. THIS HAPPENS EVERYTIME THE EARTH MOVES AND WE MOVE ALL THE TIME!!! WHICH MEANS THAT RIGHT AT THIS MOMENT THE PLATE TECHTONICS ARE MOVING.

WE HAVE 3 TYPES OF PLATE TECHTONICS, CONVERGENT, DIVERGENT AND TRANSFORM: I LIVE IN CALIFORNIA AND THE PLATES HERE TAHT INTERACT ARE TRANSFORM. NOW WE ALSO HAVE BOUNDARIES CONSIRED THEM TO BE OCEANIC OR CONTINENTAL WHEN THEY INTERACT; ITS ALL CONNECTED

oxygen, silicon, aluminum, iron, calcium, sodium, magnesium, and potassium

AS THE EARTH SPINS THE PLATE TECHTONICS MOVE AS WELL, AND THESE MAKE THE MAGNIFICENT PLACES SUCH AS THE VICTORIA FALLS BETWEEN ZAMBIA AND ZIMBAWEE IN AFRICA, OR A HIGHER MOUNTAIN PLACE TECHNICALLY THE HIGHEST PLACE MAUNA KEA IN HAWAII ( BEING A HOTSPOT, IT IS ALSO LOCATED IN THE PACIFIC PLATE.

ILL INVITE YOU TO FOLLOW THIS STEPS TO LEARN SOME PRACTICE FOR PLATE TECHTONICS

FIRST ENTER ON YOUR BROWSER;WWW.GOOGLE EARTH.COM

THEN IN THE SEARCH BUTTON TYPE THIS NEXT COORDINATES

LASTLY JUST ANALIZE THE AREA

35.13.61241, -119.675569

THIS IS AN EXAMPLE OF THE INTERACTION OF THE PACIFIC AND NORTH AMERICAN PLATE, BOTH CONTINENTAL PLATES AND WITH TRANSFORM BOUNDARIES.

19.564145, -155.479122

THIS IS AN EXAMPLE OF A HOT SPOT WHERE OCEANIC PLATES ARE INTERACTING AND THE RARE THING IS THAT THIS IS NOT A BOUNDARY

IF THERE WAS AN IMAGE ABOVE , WOULD YOU BE ABLE TO IDENTIFY THE EIGHT LAYERS OF THE EARTH? LETS SEE IF YOU DO (ITS ALL IN THE SLIDE BEFORE THE EXERCICE)

INTRUSIVE ROCKS FORMED FROM COOLING MAGMA

EXTRUSIVE ROCKS FORMED FROM SOLIDIFIED MAGMA

EVERYTHING IS CONNECTED ...

THERE ARE 4 TYPES OF VOLCANOES:

SHAPED

COMPOSITE

CINDER CONE

LAVA DOMES

METAMORPHIC ROCKS ON THE OTHER HAND were one day igneous and sedimentary, this rocks go through a process called metamorphism inside the earths crust under heat and pressure often divided into three types like dynamic, regional and contact.

THIS ROCKS RIGHT HERE ARE FROM THE GEOLOGY LAB :

The first one is called Basalt and its a black volcanic extrusive rock used for arts, construction. the production of basalt at islands locations such like Hawaii begins with an eruption at ocean floor. There are produced significant amounts of basalt in above ocean hot spot.

The other rock is Rhyolite is another volcanic rock and also extrusive. it is the most rich in silica and a fine grained rock. the mineral composition of rhyolite is plagioclase and predominantly in quartz.

I was so excited when I found out there was a cinder cone volcano that erupted 20000-50000 years ago, its called Pisgah Crater. It was not far from my house so I went to explore since I needed to put into practice my knowledge on scoria an igneous rock, ill show you the video here...

These are igneous rocks, but lets not forget about sedimentary and metamorphic rocks.

Sedimentary rocks can have different kinds of composition such as detrital, biochemical and chemical meaning that all this compounds could be quartz, feldspar, rock fragments, and clay minerals, plant fragments, charcoal, calcium carbonate, caCO3, dolomite, halite, NaCl, hematite, gypsum and some more, ending up in conglomerate, breccia, mudstone, sandstone, shale, coquina, limestone, oolitic limestone, chalk, and chert could be added to the sedimentary rock classification.

MID-TERM REFLEXION

I HAVE BEEN IN CLASS EVER SINCE IT STARTED, BUT I DO FEEL LIKE I HAVE NOT BEEN FOCUSED 100% BUT REGARDLESS OF MY WORK I'M GETTING BETTER WITH MY TIME MANAGEMENT SINCE IN MY INITIAL REFLEXION IT WAS ONE OF MY COMPROMISES TOWARDS MY OUTCOME AT THE END. AS I WAS SAYING I HAD BEEN FEELING LIKE I WAS DOING ENOUGH AND SO I DECIDED TO DROPPED ONE OF MY CLASSES AND COMPLETELY FOCUSED ON THIS VERY FUN CLASS!!

IF I WAS TO GIVE MYSELF A LETTER GRADE UP UNTIL NOW I WOULD SAY I HAVE A B OR C SINCE I HAVE BEEN GOING TO CLASS AND PARTICIPATE IN THE ACTIVITIES, BUT NOT ONLY THAT IT IS ALSO MY CLASSMATES HAVE MADE THE CLASS FUN LEARNING WITH THEM AND THROUGH THEM. IM NOT FALLING FAR BEHIND THE GOALS I HAD SET FOR MYSELF, THIS PAST TRIP TO PISGAH CRATER MADE REALIZE HOW EASY IT IS TO APPLY KNOWLEDGE INTO EXPLORING YOUR KNOWLEDGE.

KNOWING NOW ABOUT ROCKS, ILL CONTINUE TELLING YOU MORE ABOUR OTHER BEUTIFUL ROCKS TURNED INTO GEMS!!! HERES HOW

MINERALS

AS WE CONTINUED WITH OUR TOPICS THERES IS THE MOST OF THE BEAUTIFUL CREATIONS ON THIS PLANET, MINERALS ARE EVERYWHERE AROUND US AN WE EVEN USE THEM IN OUR EVERY DAY LIVES! AMAZING!

solid compounds organic or inorganic with a unique chemical composition and crystal structures in the purest form. the majority come from the earths crust some are made up of oxygen, silicon, iron, sodium potassium, calcium, magnesium, some elements that under heat and pressure THEN minerals are cooked.

an amount of minerals can be fluorescent, I applied my knowledge of minerals when I went to the San Diego Natural History Museum and found so many kinds of different minerals than the ones I had seen in class, I enjoyed learning that all mineral have different amount of an element, or maybe it was the amount of pressure or heat that maybe they are the same mineral but different color and shape.

IM IN LOVE WITH MINERALS AND I WISH I KNEW SO MUCH MORE BUT SO FAR I ENJOYED HAVING SO MANY FUN FACTS ABOUT THEM!!

practicing minerals helped me to recognized them when found them at the museum! I found Fluorite in most corners of the museum AND IF YOU PAY CLOSE ATTENTION ON THE VIDEO THEY WERE FOUND IN DIFFERENT FORMS , it was fun because the last mineral I found was fluorite, I automaticallyalready knew

Here is a link to a video of the various minerals I found most interesting and fun to look at.

*towards the end of the video if you pause it you could appreciate the different forms that minerals take, there is even a phone and yes! without minerals we would not have phones, so it is important to get to know our minerals more.

MINERALS ARE VERY IMPORTANT LIFE SUSTAINERS, VISUALLY MY FAVORITE MINERAL IS OPAL AND GALENA

Opal is a hydrated amorphous form of silica ); its water content may range from 3 to 21% by weight, but is usually between 6 and 10%.

GEOLOGY.COM IS A GREAT SOURCE TO FIND MORE INFO ABOUT THIS BEAUIFUL EARTH CREATIONS

LETS CONTINUE WITH OUR FUN ANCESTORS THE DINOSAURS AS THEY FOUND EVIDENCE OF FOSSILS FOR THE "GEOLOGIC TIME"

I WENT ON ANOTHER TRIP TP THE SAN DIEGO MUSEUM TO FIND THE AMOUNT OF FOSSILS IM ABOUT TO SHOW YOU...

William "Strata" Smith worked as a surveyor in a coal-mining and canal-building in southwestern England he found so many opportunities to look at fossils and with them he discovered that fossils could be used to correlate rocks that were the same age.

with this in mind he proposes the principal of faunal succession using sedimentary material from the Paleozoic and Mesozoic era.

He was also aware of the principle of superposition developed later on by Danish Nicholas Steno in which its stated that young sedimentary rocks form on top of older ones.

GEOLOGIC TIME DIVIDES INTO FOUR EONS: HADEAN, ARCHEAN, PROTEROZOIC, AND PHANEROZOIC.

MOST OF THE BOUNDARIES BETWEEN THE PERIODS AND EPOCHS OF THE GEOLOGICAL TIME WAS FIXED ON THE BASIS IN CHANGES THAT WERE SIGNIFICANT ON THE FOSSIL RECORD. Example the boundary between cretaceous and Paleogene coincides exactly with the extinction of the dinosaurs.

At the museum I found fossils and I almost did not think it was real, but those were legit. the next video has some examples I encourage you to go to Natural History museum and explore.

now that we know fossils, its easy to do research since where we stand could have been the home of a mammoth ages ago think about it

Final Reflection

When I started this class my whole schedule changed and plus it was an eight-week class . I thought that not only being a short term class my assignments were going to be time consuming, and I was in class 96% of the entire semester. In terms of presence I believe it to be a 90 percent. I'm only being honest with myself and this participation even means I was taking notes and making sure I was studying them outside the class which i was spending five to eight hours a week to keep up with my knowledge, I wanted to see how good I was able to manage on my on but it was often when I would talk to doctor Cooper she was always reachable

However, practice work was really good since I went from not knowing anything to actually knowing and differentiating minerals and some rocks. the e portfolio was the most creative assignment I have done so overall I could grade it to be a good learning method.

I loved everything about it even my flaws because i actually did learned from what I did, interacting with peers, presentation experience, it was a diverse of ways that were included in this whole class because her I'm only giving you previews but she got the real deal in information.
