How Earth Resembles a Gooey Confection

Posted by timothy on from the distinct-lawyers-of-slime dept.

Ant contributes a link spotted on Neatorama that may upset middle school Earth Science teachers, writing "LiveScience says Earth's simple schematic is not core, mantle, and crust anymore. It is more like the gooey center of a chocolate morsel harboring peanut butter and honey. Inner Earth is far more nuanced than outward appearances would suggest. A new model is proposed in the May 2, 2008, issue of the journal Science."

      Sir, your post is all over the place.

      What various anti-intellectuals do not understand is that Theology is about one set of things and Science is about something else.

      You are quite wrong. Christian Theology, the belief in a single sovereign God, having been based on God's written word, is "about" all things pertaining to God's adequacy and right to rule humankind, and therefore includes the origin of everything (and we are an object property of said everything).

      Science is "about"

      the universe around us, and that includes us as well. This is why science is naturalistic: it is all about natural processes and natural events. Science involves both description, which tells us what has happened, and explanation, which tells us why it happened.

      So then, you see, both the Bible (which term I will use rather than Theology, since when referencing theology you must be specific as to whose theology) and Science attempt to tell us What has happened: the physical space of the universe came into existence, followed by the stars and other heavenly bodies, geological formations occurred on earth while sitting in the midst of waters, vegetation began to live 'according to its kind,' creatures of the sea began life, then winged creatures of the sky ('heavens'), then living beasts on the surface of the ground; finally, mankind emerged on the scene, was superior to all of these previous lifeforms and was made out of dust (and Science certainly agrees that humans are composed of many of the same elements as dirt).

      They also attempt to tell us Why it happened. The Bible says that God 'created the earth even for it to be inhabited,' or in other words, made the earth as a perfect home to host his creations. Science does not really have an explanation to 'why,' but empirical evidence over thousands of years has proven true the fact that the earth truly is a wonderful home to life on it. Science agrees with this too, in that the placement of the earth relative to the Sun is just right to keep us from freezing and from frying. The combination of gasses that make up our atmosphere are just right to keep everything from being either wholly flammable or toxic to breathe.

      Relegating religionists and promoters of intelligent design to this class you deem 'anti-intellectual' really couldn't be more wrong. If one takes the time to discern what the Bible really says regarding creation, they will find it quite stimulating as well as accurate.

      Speaking to the aforementioned point and also to your objection on the matter of light--

      God introduced this fundamental division of time on the first "day" of the period during which he prepared the earth for mankind, when diffused light evidently penetrated the swaddling bands, thus causing the moisture-covered earth to experience its first day and night as it rotated on its axis through the light of the sun. "God brought about a division between the light and the darkness. And God began calling the light Day, but the darkness he called Night."

However, the record thereafter goes on to use the word "day" to refer to other units of time of varying length.

      It is not as simple as LiveScience apparently paints it - the low velocity seismic zones are well-known to geologists and have been explained by theory fairly completely.

      Though this isn't what they're talking about, there are different zones of seismic velocity within the layers themselves due to changes in temperature, pressure, and composition of the material, which leads to zones of partial melting. Seismic waves either slow down or disappear completely in liquids, depending on the type of wave, which explains some of these zones.

      What this article discusses is not those zones, obviously, but rather the boundary between layers. There are a lot of thoughts on that, too, and it's well known that the boundaries are not so distinct and perfect. For example, mantle plumes (which form hotspots like Hawaii and Yellowstone) have many theories of origin - one of them being that they originate near the core. If this were true, then there would be hot plumes of material reaching all the way through the earth to the core, which obviously would cause irregularities in the layer boundaries - creating zones of partial melting which slow down seismic waves.

      What this new article offers is a model of this behavior based on extended sets of data not available before. It's not really telling us anything too new, rather, it's describing and confirming what was already theorized using some nice new data (which is of course equally important as coming up with totally new ideas, but not as glamorous.)

Nowadays, you can pick these things up by hanging out and contributing in online forums, newsgroups, mailing lists, and IRC chat channels. These communities of practice learn expert-grade information, but it also allows techniques to evolve and for new techniques to propagate quickly; in this sense, these communities can actually be better than classic forms of learning.
