1. Earth's outer core is best inferred to be

Answers

Answer 1

Answer:

Answer:

liquid, with an average density of approximately 11 g/cm3

Explanation:

Answer 2

Answer:

Final answer:

The outer core of the Earth is inferred to be a liquid layer composed of iron, nickel, and sulfur, compressed to a high density. It's responsible for generating Earth's magnetic field due to the circulation of the liquid metal inside. Notably, its diameter makes it larger than the planet Mercury.

Explanation:

The outer core of Earth is inferred to be a dense, metallic layer, over 2900 kilometers beneath the Earth's surface. It's chiefly composed of iron, nickel, and sulfur, compressed to a very high density. Quite fascinatingly, the outer core, unlike the solid inner core, is liquid.

This liquid state facilitates the circulation of metallic elements within it, helping generate Earth's magnetic field. As the liquid metal inside Earth moves, it sets up a circulating electric current, which subsequently produces a magnetic field.

For size perspective, it's worth noting that with a diameter of approximately 7000 kilometers, Earth's core is larger than the planet Mercury. This fascinating core, and particularly its outer liquid layer, provides key insights into understanding not only earth's geodynamic movements but also the formation of its protective magnetosphere.

The part of the eye responsible for fine-tuning the refraction of incoming light is the _____. lens retina optic nerve cornea

Answers

The answer is the lens.

The eyeball is filled with a water-like fluid. In front of the eyeball, there is the cornea. It is a transparent structure that refracts light. A portion of light passes through the pupil which allows light to enter the eye. The amount of light that will pass through the pupil depends on dilatation of iris. Once the light enters the eye, it enters the lens. Lens of the eye is able to change its size and that way is responsible for fine-tuning the refraction of the light. The light later reaches the retina.

Answer:

The part of the eye responsible for fine-tuning the refraction of incoming light is the LENS
