which layer of earth is the densest and why is that so?
a. the outer core is densest due to gravitational compression
b. the outer core is densest due to generation of radiogenic heat
c. the outer core is densest due to accretion
d. the inner core is densest due to gravitational compression
e. the inner core is densest due to generation of radiogenic heat

Respuesta :

The inner core is densest due to gravitational compression. Iron and nickel are also its components, but the pressure is so great that it is no longer liquid.

What is the inner core of the Earth comprised of?

The Earth's inner core contains even more metal than the outer core. Both are primarily comprised of iron with a small amount of nickel. However, lighter elements like oxygen, carbon, and silicon are also assumed to be present in small amounts in the iron.

What is the inner core's thickness?

800 kilometres. The core of Earth is its deepest layer; it is divided between a liquid outer core and a solid inner core. The inner core is 1,200 kilometres (746 miles) thick, compared to the 2,300 kilometres (1,429 miles) thick outer core.

The strongest gravitational compression occurs in the inner core. It also contains iron and nickel, but due to the intense pressure, it is no longer liquid.

What materials make up the Earth's inner core?

Even more metal than the outer core of the Earth can be found inside. With a minor bit of nickel, iron makes up the majority of both. However, it is also believed that the iron contains trace amounts of lighter elements like oxygen, carbon, and silicon.

What is the thickness of the inner core?

800 kilometers away. The deepest layer of the Earth is its core, which is made up of a solid inner core and a liquid outer core. The outer core is 2,300 kilometers (1,429 miles) thick, while the inner core is only 1,200 kilometers (746 miles) deep.
