- The Earth is made out of many things. Deep inside Earth, near its center, lies Earth's core which is mostly made up of nickel and iron. Above the core is Earth's mantle, which is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals. The rocky surface layer of Earth, called the crust, is made up of mostly oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Earth's surface is mainly covered with liquid water and its atmosphere is is mainly nitrogen and oxygen, with smaller amounts of carbon dioxide, water vapor and other gases.

- The core of the Earth is tremendously hot, so hot that the electrons in the iron have been stripped from the nuclei of the atoms. Since it's spinning, the charges are moving, so you get a magnetic field. The real situation is far more complicated, as life, in general, is messier than an oversimplified movie review.The Earth's core isn't just spinning; there are currents inside it, and other factors which influence the Earth's magnetic field.he real situation is far more complicated, as life, in general, is messier than an oversimplified movie review.

- Finally, we would reach the Earth’s inner core. The inner core extends another 900 miles inward towards the center of the Earth. It is believed that this inner core is a solid ball of mostly iron, and nickel. The mantle is made of much denser, thicker material, because of this the plates float on it like oil floats on water.

The truth about MASH Here are the facts. Most of the MASH crew worked the entire eleven-year run of the show. If they were so miserable they would have bailed for other shows. The economy was actually good back then and there were other shows to go to.

Satellite-based earthquake detection mooted Scientists who used a satellite to detect sound waves from the 2011 earthquake in Japan say space-based earthquake detection is possible, albeit some way off. Scientists who used a satellite to detect sound waves from the 2011 earthquake in Japan say space-based earthquake detection is possible, albeit some way off.y Richa Malhotra. We may one day be able to detect earthquakes in remote areas of the Earth from space, say scientists who used a satellite to pick up low-frequency sounds from the earthquake that hit Tohoku, Japan, in March 2011. The researchers report that the satellite is the first seismometer in orbit.

How Do We Know What's in the Earth's Core? PM Explains The core's heat is mostly due to the slow decay of radioactive elements left over from when the planet first formed. The molten iron outer core lies about 3000 kilometers below our feet, while the solid iron inner core is another 2000 kilometers further down. A few other elements, including oxygen and silicon, are thrown in for good measure. But for the most part, iron rules the Earth's underbelly.

What is Earth Made Of? Scientists believe that this core is comprised mostly of iron, around 80% of it, which were pulled together and into the planet’s middle during it’s formation about 4.5 billion years ago. The earth is a lot more than what our eyes can see and is truly a spectacular, curious thing.

- Earth can be divided into three main layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. Both the inner and outer core are made up of mostly iron and a little bit of nickel.et's start from the inside and work our way out. Earth has a core, but this is really two distinct parts: the inner core and the outer core. Both parts of the core are made up of mostly iron and some nickel. The difference is that in the inner core, those minerals are solid and in the outer core, they're liquid.

- The Earth is made up of four distinct layers: The inner core is in the centre and is the hottest part of the Earth. It is solid and made up of iron and nickel with temperatures of up to 5,500°C. With its immense heat energy, the inner core is like the engine room of the Earth. The outer core is the layer surrounding the inner core. It is a liquid layer, also made up of iron and nickel. It is still extremely hot, with temperatures similar to the inner core. The mantle is the widest section of the Earth.

- Geologists hypothesize that the Earth's center is composed of predominantly iron. The outer portion of the center, known as the outer core, is thought to be liquid iron. While the interior portion of the center, known as the inner core is thought to be solid iron. This hypothesis is based upon two important observations. First, energy waves known as shear waves do not travel through the outer core. Secondly the Earth has a magnetic field.

- How do scientists know that the Earth's core is made out of Iron and not another magnetic metal? Question Date: 2012-05-03: Answer 1: Seismic waves that travel through the core move at a velocity that depends on the properties of the material the waves move through. The best fit is with iron, Fe. A second reason is that Fe is by FAR the most abundant metal in the UNIVERSE. Many meteorites have significant amounts of iron in them in the Native state.

- pretty much all dorito flavors were amazing in the early 90s. the chip itself was thicker and cooked in trans-fat which gave it flavor, now they are thin, light, nasty-tasting, flavorless. i've tried almost all current flavors and none of them compare to the doritos from the late 80s early 90s.
