Rocks and Rock Cycle

3 Types of Rock: Igneous, Sedimentary & Metamorphic | AMNH

A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed. And there are three types of rocks. the sedimentary, the metamorphic, and the igneous rock. Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment. Metamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing). And Igneous rocks are formed when magma (molten rock deep within the earth) cools and hardens. Sometimes the magma cools inside the earth, and other times it erupts onto the surface from volcanoes (in this case, it is called lava).

HOW ROCK CHANGE

Interactives . The The Rock Cycle . The Rock Cycle — **Heat and Pressure** – A similar process happens to rocks beneath the earth’s surface. Due to movements in the crust, rocks are frequently pulled under the surface of the earth, where temperatures increase dramatically the farther they descend.

The rock GIF on GIFER - by Meziktilar — **Weathering and Erosion** – All objects on the earth’s surface are exposed to the wind, along with many other elements — water, the sun, temperature changes. Over time, these factors wear objects down and break them apart. The resulting bits and pieces of material are called sediment.

Rock GIF on GIFER - by Gravelbringer — **Melting** – The same thing happens to a rock when it is heated enough. Of course, it takes a lot of heat to melt a rock.

Over time, sediment accumulates in oceans, lakes, and valleys, eventually building up in layers and weighing down the material underneath.

Animated GIF - Imgflip — **Cooling** – Similarly, liquid magma also turns into a solid — a rock — when it is cooled. Any rock that forms from the cooling of magma is an igneous rock.

These are the five processes by which rock is formed and changed. After learning these processes, i am very surprised and amazed because i learn that that´s how rocks form and change.

ROCK CYCLE

A useful way to illustrate how the three main types of rock are related to one another and how changes to rocks happen in a recurring sequence is the rock cycle. It can be presented in a diagram in the right side.

The discussion went well; I learned a lot about rocks. After I studied and answered the rock cycle interactive questions, I learned a lot about the types of rocks, which are sedimentary, igneous, and metamorphic rocks, how rocks are formed and changed, and the rock cycle. It’s fun to study rocks and the rock cycle because it’s amazing how rocks form and change. This is also one of the reasons we live on such a lovely planet. This blog will end here. See you on the next blog!

Minerals

A mineral is a characteristic chemical composition, crystal form, and physical properties. There are five criteria for minerals: minerals are solid; naturally-occuring; inorganic, or should not belong to any class of organic compound; minerals have fixed chemical formula; and the last criteria is that minerals have a specific atomic structure. We were also able to identify if the spherical things were minerals or not. Ans we also discussed the different structures of minerals and the physical properties of minerals.

It is very refreshing to study this kind of lesson. It´s amazing that even if we can´t see the different minerals in person, it´s refreshing to see or to study them even just in pictures. There are many different types and structures of minerals, and by studying them, I learned something other than what I already knew about them. And we are studying this because we are increasingly dependent on mineral materials to create products that support our way of life, our health, and the global economy.

Exploring The Layers of The Earth

” Exploring the layers of the earth is like reading the pages of the book”
~James W. Mercer

In our discussion about the layers of the Earth, there are four compositions of the earth. These were the crust, mantle, outer core, and inner core. The crust is the outer layer of the earth, and it is like the peel or rind of an orange. The mantle is the thickest layer of the earth. The mantle is hot, dense, dark rock and it represents about 68% of the Earth’s mass. The third layer is the outer core. It is made from iron and nickel, in liquid form. And the fourth layer is the inner core. It is a solid metal ball, extremely dense and also made mostly of iron and nickel, just in solid form.

4 Layers Of The Earth: What Lies Beneath Earth's Crust

In my reflection, we are studying the layers of the earth to find out what the things behind and beneath us are. I know a lot of us have many questions about what is behind and beneath us, and so by studying it, some of our curiosity and questions might be answered. This topic taught me a lot, and it’s exciting to learn more about our planet Earth. This blog will end here. I will see you on the next blog!

Life on Earth

We have discussed the factors that make our planet capable of sustaining life. These factors are liquid water, the earth’s distance from the sun, the atmosphere, the moon’s influence, temperature, energy, a strong magnetic field, nutrients, and greenhouse gases. These are the elements that contribute to our planet’s habitability and ability to support life. We have also discussed the earth’s subsystems. These are the atmosphere, which is the set of layers of gases, the hydrosphere, which is the liquid component of the earth, the geosphere, which is the solid sphere of the earth, and the biosphere, which is the living sphere of the earth and the totality of all ecosystems on the earth.

Fundamentals of Earth's Sphere - Interaction Between Spheres

Each factor that makes our planet habitable is very important because one of them should not be lost. When one is lost here, the planet will not be capable of sustaining life. The earth’s four subsystems are also important because this cycle shows why each subsystem of the earth is important and how they need each other.

We are studying those factors for us to know their worth as well as the significance of why we should care for our planet. For us to know what these factors are, the earth is capable of sustaining life. It also answers our questions about why the Earth is the only planet capable of supporting life.

The Origin Of The Solar System

If we talk about the Solar System, a lot of questions will come into your mind, like how it was created, when it was created, and more. It is hard to say and answer these questions without concrete evidence of how it was created. After the discussion about the theories on the origin of the solar system, I learned the age of the solar system and the different theories that could somehow answer my questions about the solar system.

The Death of our Solar System We have learned now that the sun is fueled by the - Window To Infinity

Based on what I have learned in our discussion, the age of the solar system is approximately 4.45 billion years old. In our discussion, there are three theories about the origin of the Solar System. These are the Protoplanet Theory, the Encounter Hypothesis, and the Nebular Hypothesis. The theory that I believe the most is the Nebular Hypothesis. It was said to be the most accepted theory that explains the origin of the Solar System. The Nebular Hypothesis also explains why planets and stars usually spin in the same plane and direction, as well as the arrangement of the planets.

The discussion went well. I learned a lot about the theories on the origin of the Solar System. It was just amazing to think about and learn how the Solar System and the planets were created. I am looking forward to the next discussion and for my next blog about our solar system and the universe. This blog will end here. See you on the next blog!

Theories On The Origin Of The Universe

” Something pretty mysterious had to give rise to the origin of the universe.
~Richard Dawkins

When talking about the universe, there are a lot of questions that are hard to answer. No one knows how the universe was created or where it came from. That´s why we are studying the different theories of the origin of the universe to know and to have an idea of how our universe was created. After studying different theories on the origin of the universe, I’m a little enlightened, but I still have many questions. In life, we have many questions that are hard to find the answer to.

What are the theories about the origin of the universe?

The End of Everything' explores the ways the universe could perish | Science News

There are a lot of past and modern theories on the origin of the universe. In past theories, these include the Creationism theory, where God is the creator of everything, the Theory of Anaxagoras, the Atomic Universe, where everything is composed of atoms, the Geocentric model of the universe, and the Heliocentrism. In modern theories of the universe, these include the Oscillating Universe, the Study State Theory, which believes that the universe is always expanding but maintaining a constant density, the Multiverse Theory, and the Big Bang Theory.

It’s fun to study the universe. There’s a lot to learn and it feels like you are travelling the whole universe. For me, the theory I believe the most in past theories is the Creationism Theory, because I believe that our God made everything. In modern theories, it´s the Big Bang Theory, because it is the most accepted theory that can explain the origin of our universe. It started with pure energy, to explosions, and to inflation, and turned into four fundamental forces, which are gravity, electromagnetic force, strong nuclear force, and weak nuclear force.

Understanding Our Solar System

“The Solar System is completely wide open. Almost everywhere we go, I´m sure we would learn a lot.“
~ Alan Stern

Disclaimer: The content of this blog is about how I personally approach our lessons in earth and life science subjects. I will be sharing my journey and my reflections in our lessons during our synchronous class. All the contents of this blog are just my reflections and opinions.

To be honest, in my first synchronous class in the subject or earth and life science, I was a bit surprise because the first thing studied was the different solar systems related to the Greek methodology. it was just surprising because I don´t know and I dont remember studying like that. but yeah, it was a good start and I really learned a lot on my first day of class in earth and life science subject.

What is solar system? What are the parts of the sun? Why is earth peculiar?

Based on what I have learned from my class, the solar system is the sun and all the objects that orbit around it. the sun is orbited by planets, asteroids, comets, and other things. Our sun is composed of eight parts. These are the core, which is the center of the sun, the radiative zone, which is the section of the solar interior , the convection zone, the photosphere, the chromosphere, the corona, the sun spot, and the solar flare. And lastly, why is the earth peculiar? simply because it is the only planet that is habitable.

It was a good start, the topic/lesson was very interesting, and I´m looking forward to learn more about our solar system and our universe. And I am sure that everyone would love to know more about it. This blog will end here. See you on the next blog!

My Journey Through Earth and Life Sciences

The Meaning of Life and The Universe

INTRODUCTION

My full name is Clarissa Silvestre de Leon, 16 years old from Laoac East, Alcala, Pangasinan. I really love bracelets and necklaces, watching and playing sports especially volleyball, and reading books. I am a Grade 11–HUMSS student at Pangasinan State University, Bayambang Campus. Actually, I am more of an introvert. I chose this strand because I am not adept at public speaking. That is my primary motivation for enrolling in Humanities and Social Sciences (HUMSS) strand; I want to increase my self-confidence, improve my ability to interact and communicate with others, improve my public speaking skills, and learn new things. And in this blog, I will be sharing my experiences in studying Earth and Life Science.

These four images are the best depict myself. I adore bracelets or anything that may be worn on our hands or wrists. I’m not sure why, but I think it’s cute and appealing. And, as I mentioned in my introduction, I enjoy watching and participating in sports, particularly volleyball. I first became interested in volleyball while I was in elementary school. Finally, I chose an image of a chef in the kitchen. I know how to conduct a variety of domestic activities, but my favorite is cooking. Cooking became a way for us to bond as a family. And lastly, I am an animal enthusiast who adores dogs for their beauty and cuteness. They relieve my tension and make me really joyful.
