A) outer core
B) inner core
C) lithosphere
D) oceanic crust

Answer 1

Answer:

A.) Outer Core

Explanation:

I just took the test

Answer 2

The correct answer is option A) outer core.

Is the outer core high pressure?

The Earth's outer core has a pressure in the range of 135 to 330 gigapascals (1.3 million to 3.3 million atmospheres) and a temperature in the range of 4,000 to 5,000 Kelvin (3,727 to 4,727 degrees Celsius or 6,740 to 8,540 degrees Fahrenheit).

The outer core is the third layer of the Earth. It is the only liquid layer and is mainly composed of metallic iron and nickel and a small number of other substances. The outer core is responsible for the Earth's magnetic field. When the earth rotates, the iron in the outer core of the liquid moves.

Dynamo theory considers the eddy currents of the outer core nickel-iron liquid to be the main source of the Earth's magnetic field. The average magnetic field strength of the Earth's outer core is estimated to be 2.5 millitesla, which is 50 times stronger than the magnetic field on the surface of the earth.
