Scientists discovered that the inner core of Earth is a solid. Explain what evidence supports this thinking. Be sure to include
Anni [7]

Explanation:

From the studies done on seismic elastic waves, it has been discovered that the innermost core of the earth is a solid concentric layer. Seismic P and S waves can be propagated through solids but the s-waves are cut off in contact with a liquid medium. This is because s-waves are shear waves and fluids do not shear.

  • At the outer core, the s waves is cutoff and it reappears in the region of the inner core.
  • This shows that the inner core is solid.
  • The inner core is made up of iron and nickel with some other siderophiles.
  • At the inner core, the pressure is very great. Pressure here is about 350gigapascal.
  • This huge pressure compresses matter into solids despite the very high temperature.
  • Also, during the differentiation of the earth, the heavier minerals moves downward to the core due to their density. Metals in the core have density of about 13g/cm³.

Most fat-soluble nutrients are absorbed in the _______ system. Question 19 options: vascular lymphatic neurological adrenal
Leya [2.2K]

Most fat-soluble nutrients are absorbed in the Lymphatic system.

<h3>What is Lymphatic System?</h3>

A network of tissues, veins, and organs known as the lymphatic system collaborates to transport lymph, a colorless, watery fluid, back into your circulatory system (your bloodstream).

Your body's arteries, smaller arteriole blood vessels, and capillaries each day carry about 20 liters of plasma. About 17 liters are then returned to the circulation through veins after providing nourishment to the body's cells and tissues and collecting their waste products. The remaining three liters permeate your body's tissues via capillaries. The lymphatic system gathers this extra fluid, which is now known as lymph, from your body's tissues and transports it to various locations before returning it to your bloodstream.
