The pressure in the center of the Earth is so high that the iron is in a solid state. Scientists have obtained most of this information from natural geological activity. What evidence indicates that the outer core in liquid? ozone layer protects us from. Seismic recodrings of earthquakes far away give evidence that the outer core is liquid. Evidence from earthquake waves indicates that the outer core is liquid. In 1906, a scientist found a boundary between the mantle and the core. ultraviolet radiation. We need you to answer this question!
Why is the inner core solid even though it is hotter than the outer liquid core? Earth consists of four major layers: the crust, mantle, outer core and inner core. While most of the layers are made of solid material, there are several pieces of evidence suggesting that the outer core is indeed liquid. our knowledge of the composition of the earths core comes from ? analysis of earthquake waves. what does the green house effect cause.
The Earth's outer core is a molten layer primarily composed of iron and nickel. Currents in the Earth's molten iron core create the planet's magnetic field. A seismograph observed that P waves were bent around the liquid outer core beyond about 100 degress away from the Earth . The great pressure at Earth's center forces the atoms in the core together, causing it to solidify. What evidence led to scientists to conclude that Earth's outer core is liquid? What evidence indicates that earths outer core is liquid? No S type of seismic waves are detectable at some locations after an earth quake. Evidence from earthquake waves indicated that the outer core is liquid. Earthquakes send seismic waves. what evidence indicates that part of the earth's interior is liquid . Compare the physical properties of the asthenosphere and the lithosphere. Its outer boundary lies 2,890 kilometers beneath Earth's surface. To this day, scientists have not been able to directly observe the Earth's core, but they have figured out how to determine what elements, and what states of matter, compose the inner and outer core. The speed and angle that the waves reach the seismic observatories are best explained by a liquid outer core. Density, seismic-wave data and Earth’s magnetic field provide insight into not only the structure but also the composition of Earth’s core. Which metal is likely to be denser: nickel or iron?
