Environmental Science Day 2: What are the physical systems that affect the Earth?

Source: http://www.eduweb.com/portfolio/earthsystems/parent_page.html

Our Earth is greatly affected by a variety of processes and cycles that occur on our planet. Each of these systems are affected by energy, matter, and how though components are converted and exchanged between localities and components of our planet. They also interact with each other to change how these materials shift through the planet and how they are used by organisms on our planet. 

Some of the most commonly studied Earth Systems are: 

  • The Lithosphere, also known as the geosphere, which includes the inner portions of our planet, the plates that make up the crust of our planet, and how the plates move and produce geologic events. Essentially, the “land”. 
  • The Atmosphere, which is all of the Earth’s air and those things found within it, including clouds and other particles, as well as our ozone layer. 

  • The Hydrosphere, where all of our water is on Earth, as ice, liquid and vapor, as well as underneath the Earth’s surface. 

  • The Biosphere, the collection of all of the Earth’s life forms 
There are a few other systems that are specifically studied, such as the cryosphere: the system of the Earth’s glaciers and frozen ice; and the heliosphere: the sun, the region of space it occupies and how it affects the Earth and it’s systems. 
Needles to say, a lot of these systems overlap quite a bit. The cryosphere can really be thought of as a subset of the hydrosphere, given that all frozen water is water; but glaciers affect our planet’s radiation and ability to trap heat so much that it needs its own field of study. Similarly, the biosphere can be considered an amalgam of all of these other spheres, incorporating water, minerals from the Earth, air from our atmosphere, and even energy from our sun to become what we think of as life. However, life has so many other complex interactions and unique stipulations that it also has its own system. 

Since these spheres are so closely interconnected, a change in one often results in a change in the other. All of these spheres interact together in ecosystems, which we defined earlier on 7DoS as the sum of all living and non-living things in a physical location. Needless to say, the sum of all physical spheres of a location could also be used as a definition for an ecosystem. 

Understanding how events impact each sphere independently and together is an important aspect of environmental science. For example, when considering airborne pollution generated by human manufacturing, one has to of course look at how that pollution affects the atmosphere. However, some of those particles may also settle into streams and other sources of water nearby; thus, we also have to look at the hydrosphere. These pollutants will get into the lungs of humans, birds, and other animals as well as be absorbed by plants and other organisms. Thus, we have to look at how pollution affects the biosphere. This is how environmental science becomes so complicated and intricate - little things can affect so many aspects of so many different parts of our planet. 

Next week, we’ll look at energy specifically, and how it cycles through the Earth System as a whole.

The Sun’s Ballerina Skirt

The Sun’s magnetic field is the cause of many spectacular phenomena that we witness on Earth: the aurora that we see from the solar wind interacting with the earth’s atmosphere, coronal mass ejections where the magnetic field carries plasma into space, and sunspots, just to name a few. As the Sun rotates, this magnetic field gets twisted up since the rotation at the equator is faster than the rotation at the poles. At the equatorial plane, where the polarity of the field changes from north to south, there is a heliospheric current sheet—a blob of plasma with a small electrical current flowing through it which extends throughout the Solar System. This current sheet has a funny geometry, one that is called an Archimedian spiral. In mathematical terms, this means if there was a line drawn from the center of the Sun outwards in space, the spiral arms would have the same distance from each other along the line. Because of this shape, the strength of the solar magnetic field is much greater in the outer Solar System than if the Sun was not rotating.

For more on the Parker spiral (named for the solar physicist who predicted the solar wind and much of its behavior), consider downloading Wolfram Demonstration’s visual interactive for free. It can be found here.

I can’t believe Heliosphere is already a year old!

Honestly, I didn’t think my project would get this far! Since it’s an original one, I didn’t think that it would nearly get as much feedback as some of my other fanart. But this project is fun, and I’m so happy with the amount of support it’s getting! Including the fanart and help with ideas, gosh you have no idea how much I appreciate that! Whenever I receive some sweet fanart I die a little inside because it’s a death by giggles and squeals!

And it’s thanks to your help that the Uranian moons are FINALLY UP! So, here are the updates to the site! I hope you guys like it!

Heliosphere Tumblr site updates:

  • New theme songs are up and are continually updated! And as for the Uranian moons, their main theme song is FREEDOM DiVE↓.
  • Find the theme song of your favourite character!

  • Visitor and hit counter is now up, plus a scrolling text on your browser tab! We hope you have fun on your galaxy tour as a visiting comet! 

Read more in my deviantART account.
Seriously though, thank you guys for the continuing support! The blog itself isn’t actually a year old, but the project is! I started this blog about… four months after the project started, more or less. Again, thank you and we hope that you will enjoy more heliospheric and galactic fun!

Tektite was born within the Sol system, but not on earth.  She was formed on Jupiter’s most massive moon, Titan.  The satellite’s dense atmosphere brewed intense storms that pummeled the surface.  Being somewhat of an immaculate conception, Tek had no other gems around to guide her on how to form, so the process was lengthy and repetitive.  

When she finally harnessed the power of her gem and learned to channel lightning, Tek found she had the ability to travel and leave her world.  In a flash she was able to visit all the planets in Sol, including earth.  After much observation, she determined that humans would not react well to her presence, so she remained on Titan and vowed to protect earth from any invaders trying to enter the Sol system from outside of the heliosphere.

Because she is so accustomed to the frigid temperatures of Titan and space, earth is almost unbearably warm to her.  If Tek must visit the planet, she does so either at night or during rainstorms.

Her weapon is a long, needle like spear with a cross shaped blade.  It’s pulled from the raw-cut gem on the back of her head.

Hi there!! I'm doing a monograph on the heliosphere, and I read that past the termination shock, the solar magnetic field gets stronger. I haven't found any information on how much stronger it gets, but my professor wants me to quantify the specific increase in Gauss. Do you have any idea of where I could find that information? Thanks!

That’s a cool topic! I actually haven’t read much literature on the heliosphere but I know the Voyager 1 spacecraft has recently exited the heliosphere and has realtime data here on the magnetic field.

That’s raw NASA data so I’m not sure if it’s going to be in terms of what you’re looking for. If not, I recommend using google scholar to find some papers that will have been written recently on the Voyager mission. Good luck and let me know what you find! :)

The following is a thorough explanation of how DNA and human consciousness are completely interconnected, along with how this is related to the merging of the Sagittarius Dwarf Galaxy and the Milky Way Galaxy.

Filaments are unstable strands of solar material suspended above the sun by magnetic forces. Solar astronomers around the world had their eyes on this unusually large filament and kept track as it erupted. Both of the coronagraph instruments on the joint ESA/NASA Solar and Heliospheric Observatory, or SOHO, show the coronal mass ejection associated with the eruption. http://b4in.com/rOzo

“The top image was taken by SOHO’s LASCO C2 coronagraph and the bottom by LASCO C3.”

“LASCO, which stands for Large Angle Spectrometric Coronagraph, is able to take images of the solar corona by blocking the light coming directly from the Sun with an occulter disk, creating an artificial eclipse within the instrument itself. C2 images show the inner solar corona up to 8.4 million kilometers (5.25 million miles) away from the Sun. C3 images have a larger field of view: They encompass 32 diameters of the Sun.”

“To put this in perspective, the diameter of the images is 45 million kilometers (about 30 million miles) at the distance of the Sun, or half of the diameter of the orbit of Mercury. The white circle in the center of the round disk represents the size of the sun, which is being blocked by the telescope in order to see the fainter material around it.”

For the Heliosphere anniversary (May 22), I’m not sure what I’ll do but I’ll make sure I thank everyone who’s supported my project! I’m just really not ready for it and I’m HONESTLY surprised with the amount of support it’s getting despite it not regularly updated with comics.

And I think I’ll post an Eris cosplay makeup test for a day. Camera shy but it’s like a token of gratitude hehe
