Rock and Minerals.

   Well hi :) The topic for our second week at NS is about rock and minerals. For introduction of the topic, inform yourself about Elements and Matter first.  Studying about with these two makes me miss my childhood when I dont have to worry much about my plates and just enjoying reading books alone.  Moving on, let me tell you about Minerals an Rocks.

Rocks and Minerals

    Mineral is a solid inorganic substance of natural occurrence. Minerals are can be formed by crystallization of magma, precipitation, pressure, temperature and through hydrothermal solutions. Minerals can be classified based on their composition: Silicates, Carbonates, Oxides, Sulfates and Sulfides, Halides and Native elements.  Their are also different properties of Minerals, these are: color, streak, luster, crystal form, hardness, cleavage, fracture, density, and other distinctive properties.


      The second part of the topic is about Rocks, well I'm not obviously talking about rock and roll but I'm talking about Rock that means solid mineral material forming part of the surface of the earth and other similar planets, exposed on the surface or underlying the soil or oceans. Rocks are also rockin' cool cause it have different types: Igneous, Sedimentary, Metamorphic, Magma, Lava, Weathering, and  Sediment. 




And also, Rock is also considered Rock and Roll cause it been through a roll or a cyle which is illustrated below: 

Rock Cycle

   I enjoyed learning about Minerals and Rocks cause some of it look so cute and colorful, its really wonderful and interesting to know how they're built cause they look great and amazing with only the help of nature. And also we also discuss about diamonds and how to know if it's fake or not. You can watch the video below so you can know about it too.  :)

Earth Science (Introduction)

          Here's our first day discussion at NS. It's about Earth Science, which serve as our review cause we already discuss this on our lower years of study.

          First of all, we have to define Earth Science, well it is the branch of science that deals with the physical constitution of the earth and its atmosphere. Earth Science includes  geology; the study of Earth,  oceanography; the study of the ocean, meteorology; the study of the atmosphere and the processes that produce weather, and astronomy; the study of the universe.

       Since were discussing about Earth here, the most widely accepted model explaining the formation and evolution of the Solar System including the earth is the Nebular Hypothesis. In the Nebular Hypothesis, stars form in gravitationally contracting clouds. The center region of a cloud contracts faster and actually forms the star but gas and dust is left orbiting and from this orbiting gas the planets form. When the center of the star becomes hot enough to generate heat by nuclear reactions (fusion) the star lights up and blows away the gas orbiting it, leaving mainly the heavier bodies such as planets. Along with the formation of Earth, layers and spheres of Earth are also formed. There are four major spheres of earth: Hydrosphere(all forms of water), Atmosphere(air), Biosphere(includes all life) and Geosphere(the crust, mantle, and core). View the Illustration below to review the Earth's Layer Structure.

Earth's Layer Structure

   Do you know that there's a theory that proposes that Earth’s outer shell consists of individual plates that interact in various ways and thereby produce earthquakes, volcanoes, mountains, and Earth’s crust itself? That process is called Plate Tectonics.    To explain further the formation of earth and plate tectonics, watch the video below

The Early Earth and Plate Tectonics

  To determine the location on the globe, there are lines that are used to determine the exact location: 

• Longitude
is distance east or west of the prime meridian, measured in degrees.

• Latitude
is distance north or south of the equator, measured in degrees.

    We also discuss about Earth System Science;a system is any size group of interacting parts that form a complex whole.Earth system science studies Earth as a system that is composed of numerous parts, or subsystems.And also Scientific Inquiry. Science assumes the natural world is consistent and predictable. The goals of science are to discover patterns in nature and to use the knowledge to predict.

Introduction.

Hi again and I am Aly, and this if my journey for science. 

Before I pursue learning art, my first interest was Science especially Astronomy. In fact, I compete at different science quiz bee when I was grade 1. I love studying science as much as i love solving math problems, and when I enter college, I miss it a lot and finally now on our third year, we have Natural Science which obey my longing for learning science again.

So before I start sharing things about science, I would like to give credits to our Professor Mr. Paner who currently teaching about this subject. You can view his latest curriculum viate HERE.
