10 interesting facts about planet Earth
1. Plate tectonics keep the planet comfortableEarth is the only planet in the Solar System with plate tectonics. The outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate can go underneath another.
This process is very important. When microscopic plants in the ocean die, they fall to the bottom of the ocean. Over long periods of time, the remnants of this life, rich in carbon, are carried back into the interior of the Earth and recycled. This pulls carbon out of the atmosphere, which makes sure we don’t get a runaway greenhouse effect, like what happened on Venus.
Without the plate tectonics, there’d be no way to recycle this carbon, and the Earth would overheat.
2. Earth is almost a sphereThe Earth’s shape could be described as an oblate spheroid. It’s kind of like a sphere, but the Earth’s rotation causes the equator to bulge out . What this means is that the measurement from pole to pole is about 43 km less than the diameter of Earth across the equator.
Even though the tallest mountain on Earth is Mount Everest, the feature that’s furthest from the center of the Earth is actually Mount Chimborazo in Ecuador.
3. Earth is mostly iron, oxygen and siliconIf you could separate the Earth out into piles of material, you’d get 32.1 % iron, 30.1% oxygen, 15.1% silicon, and 13.9% magnesium. Of course, most of this iron is actually down at the core of the Earth. If you could actually get down and sample the core, it would be 88% iron. 47% of the Earth’s crust consists of oxygen.
4. 70% of the Earth’s surface is covered in waterWhen astronauts first went into the space, they looked back at the Earth with human eyes for the first time, and called our home the Blue Planet. And it’s no surprise. 70% of our planet is covered with oceans. The remaining 30% is the solid ground, rising above sea level.
5. The Earth’s atmosphere extends out to 10,000 kmThe atmosphere is thickest within the first 50 km or so, but it actually reaches out to about 10,000 km above the surface of the planet. This outermost layer of the atmosphere is called the exosphere, and starts about 500 km above the surface of the Earth. As we said, it goes all the way up to 10,000 km above the surface. At this point, free-moving particles can actually escape the pull of Earth’s gravity, and be blown away by the Sun’s solar wind.
But this high atmosphere is extremely thin. The bulk of the Earth’s atmosphere is down near the Earth itself. In fact, 75% of the Earth’s atmosphere is contained within the first 11 km above the planet’s surface.

6. The Earth’s molten iron core creates a magnetic fieldThe Earth is like a great big magnet, with poles at the top and bottom of the planet, near to the actual geographic poles. This magnetic field extends from the surface of the Earth out thousands of kilometers – a region called the magnetosphere.
Be grateful for the magnetosphere. Without it particles from the Sun’s solar wind would hit the Earth directly, exposing the surface of the planet to significant amounts of radiation. Instead, the magnetosphere channels the solar wind around the Earth, protecting us from harm.
Scientists think that the magnetic field is generated by the molten outer core of the Earth, where heat creates convection motions of conducting materials. This generates electric currents that create the magnetic field.
7. Earth doesn’t take 24 hours to rotate on its axisIt’s actually 23 hours, 56 minutes and 4 seconds. This is the amount of time it takes for the Earth to completely rotate around its axis; astronomers call this a sidereal day. Now wait a second, that means a day is 4 minutes shorter than we think it is. You’d think that time would add up, day by day, and within a few months, day would be night, and night would be day.
Remember that the Earth orbits around the Sun. Every day, the Sun moves compared to the background stars by about 1° – about the size of the Moon in the sky. And so, if you add up that little motion from the Sun that we see because the Earth is orbiting around it, as well as the rotation on its axis, you get a total of 24 hours. Now that sounds like the day we know.
8. A year on Earth isn’t 365 daysIt’s actually 365.2564 days. It’s this extra .2564 days that creates the need for leap years. That’s why we tack on an extra day in February every year divisible by 4 – 2004, 2008, etc – unless it’s divisible by 100 (1900, 2100, etc)… unless it’s divisible by 400 (1600, 2000, etc).
9. Earth has 1 moon and 2 co-orbital satellitesAs you’re probably aware, Earth has 1 moon (The Moon). But did you know there are 2 additional asteroids locked into a co-orbital orbits with Earth? They’re called 3753 Cruithne and 2002 AA29. We won’t go into too much detail about the Moon, I’m sure you’ve heard all about it.
3753 Cruithne is 5 km across, and sometimes called Earth’s second moon. It doesn’t actually orbit the Earth, but has a synchronized orbit with our home planet. It has an orbit that makes it look like it’s following the Earth in orbit, but it’s actually following its own, distinct path around the Sun.
2002 AA29 is only 60 meters across, and makes a horseshoe orbit around the Earth that brings it close to the planet every 95 years. In about 600 years, it will appear to circle Earth in a quasi-satellite orbit. Scientists have suggested that it might make a good target for a space exploration mission.
10. Earth is the only planet known to have lifeWe’ve discovered past evidence of water on Mars, and the building blocks of life on Saturn’s moon Titan. We can see amino acids in nebulae in deep space. But Earth is the only place life has actually been discovered.
But if there’s life on other planets, scientists are building the experiments that will help find it. A new rover called the Mars Science Laboratory will be heading to Mars in the next few years, equipped with experiments that can detect life in the soil on the Red Planet. Giant radio dishes scan distant stars, listening for the characteristic signals of intelligent life reaching out across interstellar space. And new space telescopes, such as the European Space Agency’s Darwin mission might be powerful enough to sense the presence of life on other worlds.

Chip “Sees” in 3D to Diagnose HIV, LeukemiaInexpensive, portable devices that can rapidly screen cells for leukemia or HIV may soon be possible thanks to a chip that can produce three-dimensional focusing of a stream of cells, according to researchers. “HIV is diagnosed based on counting CD4 cells,” says Tony Jun Huang, associate professor of engineering science and mechanics at Penn State. “Ninety percent of the diagnoses are done using flow cytometry.”Huang and his colleagues designed a mass-producible device that can focus particles or cells in a single stream and performs three different optical assessments for each cell. They believe the device represents a major step toward low-cost flow cytometry chips for clinical diagnosis in hospitals, clinics and in the field.Read more: http://www.laboratoryequipment.com/news-Chip-Sees-in-3D-to-Diagnose-HIV-Leukemia-053112.aspx

A New Gallup Poll On Americans’ Belief in Evolution Is Out Today …
… and it’s full of rather sad figures. A full 46% of those surveyed believe that God created humans in their present form within the past 10,000 years. The number has essentially remained unchanged for the past 30 years (44% in 1982).
You can check the Gallup report for the detailed results, but a few things jumped out at me:
Among people who never attend church, a full 25% still subscribe to creationist views.
There’s only a 17% difference (58% vs. 41%) between Republicans and Democrats
Almost four out of five Americans believe God had a hand in creating humans in some way
Now, I’m not bothered by the existence or acceptance of religion, when used for good. Nor do I believe that accepting evolution means that you must deny all other religious beliefs. Sure, the more one learns about science and the universe the more one will experience the pangs of cognitive dissonance and questioned faith. But those feelings and questions are part of the human journey. They carve the unique facets of your identity that make you truly you.
What bothers me is that evolution is at the core of so much of science, and to dismiss its truth is akin to a mathematician dismissing that 1 is half of 2 or a chemist refusing to acknowledge the existence of electrons. You simply can not fully immerse your brain in the workings of our living world without evolution. Medicine, biology, nature … any of it.
And in thirty years of bloody knuckled work to bring science into people’s lives, it feels like we still haven’t gotten anywhere.
