Why do geologists assume that the Earth’s core contains mostly iron? A. the crust does not incorporate nickel. O. the crust incorporates a combination of iron and silicon. c. the lunar crust contains much less iron than the earth’s crust. the d. different orbits our bodies contain more iron than the earth’s crust.
Answer 1
The core makes up almost a third of its entire landmass. It is mainly composed of iron and nickel metals. Subsequently, the nucleus can be called nife due to the presence of these two chemical parts. This layer is divided into inner and outer core. The temperature of the outer core varies from 2,900 to 5,100 km, it is extra fluid and its temperatures vary from 3,000°C to 3,800°C. The inner core is 5,100-6,370 km and is strong. It was not until 2013 that scientists managed to identify the Earth’s core temperature, which can reach 6000 ° C, the same as that of the sun. According to scientists, the temperature of the Earth’s core is so excessive that iron will be introduced in a liquid state. The tissue, however, returns to a strong state due to stress, causing it to clump together once more.
answer 2
Geologists assume that the Earth’s core largely contains iron because the Earth has a strong magnetic discipline which is due to molten iron in the core. The fixed motion of the molten iron inside the core causes {an electric present} contained in the planet which ends in the era of magnetic discipline which extends to the area. This magnetic discipline also helps to protect people residing on this planet from dangerous photovoltaic radiation.
answer 3
1. The seismic waves passing through the core change at a speed that depends on the properties of the tissue through which the waves pass, and one of the best combinations in this case is iron (Fe).2. Iron is probably the most important metal in the universe.
answer 4
This is due to the truth of the massive variation of the magnetosphere, the Earth’s magnetic discipline. It can be attributed exclusively to metallic displacement in the chains. It’s sturdy enough to level compasses the right way, but not strong enough to keep frying pans on the ground, unfortunately.
