Despite attempts, getting through the crust has proven impossible with current economic and technological constraints. Temperatures vary from 900 to 1600 degrees F at the Mohorovicic discontinuity, the boundary between the crust and the upper mantle. And the lithostatic pressure at the line dividing the crust and the mantle is estimated to be up to 116,000 pounds per square inch. It is not surprising that drill bits and shafts would be under tremendously high stresses. Geologists look into the interior by indirect means; examination of deep sourced volcanic material, meteorite and moon material, and behaviors of seismic waves. Much can also be inferred by computer modeling of Earth's gravitational influence and magnetic field.

∙ 11y agowee cant dig into the earth very far or go there so we have to rely on indirect methods such as using seismic waves

∙ 6y agoWe can't see earth's interior, making it more difficult to determine.

Why is it difficult to determine earths inner structure?
The Earth's interior cannot be directly observed. Scientists must rely on indirect data to make hypotheses about the interior. Indirect evidences include meteorite composition, volcanic ejecta, intrusive igneous rock exposed through erosion, and the behavior of seismic waves as they travel through the Earth. They porduce youmama and fu yall It is difficult to determine Earth's inner structure because of all the layers. The Earth altogether is made up of seven layers.
How far beneath the surface is the Earths core?
It's approximately (3,963)miles down to the earths core.
What is a sentence using inner core?
inner core is the earths center .
What is the distance of the inner core?
The earth's inner core is 3160 kilometers beneath the earths surface. The inner core is a solid ball of nickel-iron alloy.
What is the source of heat in the Earths interior?
the inner core
