How does earths inner core affect seismic waves?
They go faster through the inner core than the liquid outer core
Who discovered the Outer Core?
The outer core of the Earth was indirectly discovered by detecting seismic waves that travel through it. Scientists used data from earthquakes and seismic waves to infer the existence and properties of the outer core, which lies beneath the mantle.
Who discovered Earth's core?
The British geologist Richard Dixon Oldham discovered the Earth's core and published his results in 1906.
Conclusion based on the analysis of seismic data supports the inference that Earths outer core is liquid?
there are convection currents in the upper core.
How was Earth's core discovered?
By studying how seismic waves travel through the Earth's interior.
Evidence that earths core has a high iron content from?
Scientists have determined that Earth's core has a high iron content through seismic studies that analyze the behavior of seismic waves as they pass through different layers of the Earth. By studying how these waves travel and are reflected or refracted, researchers can infer that the core must be composed primarily of iron and some nickel. Additionally, the magnetic field of the Earth is consistent with the presence of a large iron-nickel core.
Samuel de Champlain's discoveries?
he discovered aliens in the earths core and f*** mountain.
How did Beno Gutenberg discover the boundary between mantle and outer core?
He didnt just discover 'a boundary' between mantle and outer core. He provided the first reasonable accounting of Earths interior (proved the thought that the earth was in layers and not just a homogenous planet). He was also the first to estimate the temperature and physical properties of the earths core, which is why the boundary is called after him. He first discovered the layers through seismic waves from earthquakes, realising they had different magnitudes and intensity because they must have had to go through layers before reaching the surface as well as depending where the epicentre is.
How does earths solid inner core affect seismic waves?
They go faster through the inner core than the liquid outer core.
What approximate is the diameter of earths core?
Seismic data was used to estimate the radius of the Earths core. Inner = 1,221 km Outer = 2,259km Total = 3,480km Therefore an approximate diameter to the Earth core is 6,690 km or 4,325 miles. See related link for more information.
What evidence did scientists use to figure out Earths inner core is solid?
Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.
Why do scientists think earths core is made of iron?
Scientists think Earth's core is made of iron because iron is a dense material, and it is abundant in Earth's crust. Also, studies based on seismic waves and Earth's magnetic field support the idea that the core is composed mostly of iron.
