There are other planetary systems in the cosmos that are similar to ours, with planets orbiting a host star. Our solar system is named after our Sun, Sol, which is derived from the Latin word which means sun, and anything associated to the Sun is referred to as solar. In our solar system, there are eight major planets, and each one has a moon or several moons surrounding it.
Smaller planets in the solar system are known as dwarf planets, and they have moons orbiting them. Every day, nebulas generate stars in our solar system, along with comets, meteoroids, and asteroids whizzing through at great speeds, crashing into planets.
The Sun is the center of the Solar System. The Sun gives us light and produces energy for the plants and heat for us to stay warm. The Sun is not the only star in our Galaxy there are maybe about 200-400 billion stars in the Milky Way Galaxy. Earth and many other planets revolve around the Sun.
The importance of understanding the solar system has never been greater. It teaches us to value the environment. When you gaze at the stars and the galaxy, you don’t feel like you’re from a specific region of the world; you feel like you’re from the entire solar system. In our solar system, we have the most amazing planet.
THE ORIGIN OF THE UNIVERSE
Humans often try to comprehend life and how we tick as humans evolve and improve. The solution can be found in the stars, galaxies, and the universe’s origins. Humans have been trying to figure out how the Universe came to be since the beginning of time. However, the prevalent theories have only been empirical in nature in the last few centuries, since the Scientific Revolution. From the 16th to the 18th century, astronomers and physicists began to build evidence-based explanations for how our Sun, planets, and Universe came into being.
At a broad level, a Creationist is someone who believes in a god who is absolute creator of heaven and earth, out of nothing, by an actor free will. According to Leucippus and Democritus’ atomic theory- that everything is composed of “atoms”. I’m also interested to the Multiverse idea, which states that there are numerous universes that exist and contain all space, time, and matter.
The concept that morality is somehow dependent on God, and that moral duty rests in obedience to God’s orders, is known as Divine Theory. At a broad level, a Creationist is someone who believes in a god who is absolute creator of heaven and earth, out of nothing, by an actor free will.
The planets are produced in a thick disk made up of material from the gas and dust cloud that collapses to become the Sun. The density of this disk had to be high enough to support the formation of planets while remaining thin enough for the Sun to sweep away any remaining matter .
Our solar system formed at the same time as our Sun as described in the nebular hypothesis. It is an idea of spinning cloud of dust made of mostly light elements
Many attempts have been made to construct hypotheses about the Solar System’s formation. There isn’t one of them that is completely satisfactory. However, we believe we have a good understanding of the entire mechanism.
It was a good start; the topic/lesson was fascinating, and I am eager to learn more about our solar system and universe.
And I’m sure everyone would be interested in learning more about it. This is where the blog will come to an end. Look forward to seeing you in the upcoming blog!
LIFE ON EARTH
Earth—our home planet—is the only place we know of so far that’s inhabited by living things. It’s also the only planet in our solar system with liquid water on the surface.
Earth is “just right” for life as we know it. The most accessible livable planet for research will always remain Earth. As a result, examining the origins and early evolution of life, as well as the long-term evolution of the Earth’s ecosystems, aids our understanding of why the Earth became habitable and why terrestrial life has survived for billions of years.
The Earth and the Sun are equally vital since the Earth would be a lifeless lump of ice-coated rocks without the Sun’s heat and light. It controls the temperature of water bodies, weather patterns, and plant growth by providing energy. The Earth’s distance from the Sun gives it an ideal place for life to flourish since it receives just the right amount of heat and light to allow life to emerge and thrive.
As we know that the Sun is the primary source of energy to the Earth, but the only planet that optimizes the amount of heat and light which is necessary for the life process. Energy can come from many sources including the Sun, chemical reactions, and the natural heat from the Earth. This energy is the fuel for all life. Liquid water, something found in abundance on Earth, is the last needed factor. The Earth has a suitable climate for the existence of all forms of life because of moderate amount of carbon dioxide, which is the driving factor for the survival of life forms.
Land, water, living beings, and air are the four basic subsystems that make up the Earth’s system. “Spheres” refers to these four subsystems. The “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air) are the four spheres (air).
THE LAYERS OF THE EARTH
“I didn’t know then that the mind, like the earth, has a several layers: A crust, a mantle, a boiling core.”
– Lauren Slater
Why do we need to study the layers of the Earth?
It is important that we understand the earth’s layer. Earth has numerous layers: the crust, mantle and the inner and outer core. These things might seem irrelevant at first but for those who aspire to be scientist or astrologers as a career for their future. Knowing our very own planet is like knowing every parts of the human anatomy.
The layers of Earth provide geologists and geophysicists clues to how Earth formed, the layers that make up other planetary bodies, the source of Earth’s resources, and much more.
The mantle is made up of rock, silicon, iron, magnesium, aluminum and oxygen. It is divided into the upper and lower mantle, it is extremely hot but not completely hard.
The inner core is mostly made up of nickel and iron, the inner core was spinning faster than the rest of the Earth.
The outer core is the only liquid core, and this layer is responsible for the Earth’s magnetic field which protects the Earth from things that can be harmful from the sun.
The crust is the top layer we see, the mantle causes volcanoes, and earthquakes. The crust is what you and I live on .
MINERAL
Do you know what mineral is?
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties.
THERE ARE 5 CRITERIAS OF MINERALS.
- Minerals are Solid
- Minerals are naturally occurring
- Minerals are inorganic
- Minerals have fixed chemical formula
- Minerals have specific atomic structure
Solid can be crystalline and amorphous. Take note minerals cannot be liquid or gases, ONLY SOLID.
Minerals are not man made.
Minerals can be classified into one of eight group based on their CHEMICAL COMPOSITION.
Why do we need to know all the minerals?
All of the minerals were discovered and as we studied them, they actually incorporate their understanding about Earth science, chemistry, physics and math. And because minerals are basic and essential raw materials in our daily lives.
DIFFERENT TYPES OF ROCKS
Earth, being a terrestrial planet, is composed of rocks and minerals as part of geosphere. There are 3 main types of rocks- the igneous, metamorphic and sedimentary rocks.
Rocks come in cool colors, shapes, textures, and sizes and are all found around you, but how much do you really know about them? How rocks formed?
Sedimentary rocks are formed from particles of sand, shells, pebbles and other fragments of material. You can often see sand, pebbles, or stones in the rock, and it is usually the only type that contain fossils. Examples of this rock type include conglomerate and limestone.
Metamorphic rocks are formed under the surface of the Earth from the metamorphosis that occurs due to intense heat and pressure.
Igneous rocks are formed through the cooling of magma or lava. The term “igneous” is based on the Latin term ignis, meaning fire. Obsidian is one type of igneous rock.
The rock cycle is a model geologists use to explain the endless cycle of change that rocks undergo. The main idea is that rocks are continually changing from one type to another and back again, as forces inside the earth bring them closer to the surface (where they are weathered, eroded, and compacted) and forces on the earth sink them back down (where they are heated, pressed, and melted). The rock cycle helps us to see that the earth is like a giant rock recycling machine!
Do you know how rocks change? I just like to share what I have learned.
All of these can lead to the transformation of the rock depending on the process involved.
Melting– happens to a rock when it is heated enough.
Cooling– any rock that forms from the cooling of magma is an igneous rock.
Compact and cementing– the same happens to sediment formed from the weathering erosion.
Studying of rocks is important because they contain clues about what the Earth was like in the past.
And I’m sure everyone would be interested in learning more about it. This is where the blog will come to an end. Looking forward to see you on the next upcoming blog!
