Answer:

The core corresponds to almost one third of the entire earth mass. It is mainly composed of iron and nickel metals. Therefore, the nucleus can also be called nife due to the presence of these two chemical elements.

This layer is divided into inner and outer core. The outer core temperature ranges from 2,900 to 5,100 km, is more fluid and its temperatures range from 3,000 ° C to 3,800 ° C. The inner core is 5,100 to 6,370 km and is solid.

In 2013 alone, scientists were able to pinpoint the core temperature of the Earth, which can reach 6,000 ° C, the same as the sun.

According to scientists, the temperature of the earth's core is so high that iron can be brought into liquid state. The material, however, returns to solid state as a result of pressure, which causes it to group together again.

There's two main reasons why geologists think that the Earth's core is made out of iron:

1. The seismic waves that travel through the core are moving at a velocity that depends on the properties of the material the waves travel through, and the best fit in this case is the Iron (Fe).
2. The iron is the most abundant metal in the universe.

<h3 /><h3>What subjects need to be studied to study the earth's magnetism?</h3>

Paleomagnetism is the study of naturally occurring residual magnetism in rocks with the goal of understanding the strength and direction of the Earth's magnetic field in the geologic past and understanding the motion history of plates. Paleomagnetic fields have played a large role in confirming undersea propagation, through the discovery and understanding of seafloor anomalies. In the 1960s, geophysicists studied the magnetic properties of the ocean floor and began to discover some amazing properties.

The seabed has a system of linear magnetic anomalies in which a "band" has all its magnetic minerals oriented in the same way as the current magnetic field and the magnetic minerals in the bands alternating is oriented in the opposite direction. These bands are oriented parallel to the mid-ocean ridge system; where the ridges compensate for the transform error, the anomalies are also compensated. Symmetrical anomalies are found on either side of the ridge, and similar symmetry is found in ridges around the world.

The electronegative oxygen that is central to a water molecule is __________ bound to two hydrogen atoms. These hydrogens are 'b

ycow [4]

Answer:

Each molecule or compound is made up of more then one number of elements inside it, as there are different level of electronic configuration and the whole level of properties is much more different for all the elements which are involved in the bond formation. While, the elements are much smaller then any normal being can imagine it is still attributed with certain geometrical properties to the unique compounds that are more vital to the survival of living beings on this planet.
As, for the H₂O the single oxygen,O₂ atom is bonded with two hydrogen,H atoms. And to study the structure of the H₂O we might require some basic knowledge about the electronic configuration of the different elements, and for that reason we know that hydrogen has single electron in its outer most shell that is used during the bond formation of the elements with the single oxygen,O₂ atom having 8 electrons in its outer most shell. out of the 8 electrons only 4 electrons are there to take part in the formation of bonds of the element with other atoms.
While, the water molecule experience a different experience when it comes to the distribution of charge all over its structure, making it more polarized in nature. Just because there are two hydrogen,H atoms for the formation of bond with a single oxygen,O₂ atom there are two single bonds formed( which are covalent in nature). Now, there are excess of electrons present on the oxygen molecules that attracts the electron pair formed with the hydrogen to such an extent that the structure of H₂O is seemed to be a "V" shaped as a whole when observed and has the geometric angle of 105 degree in total.

The presence of lone pair electrons on oxygen or we can say presence of extra pair of electrons which are not involved in the bonding process are held responsible for the "V" shape structure of the water,H₂O molecules and the bond formed are the single covalent bonds between the hydrogen,H and oxygen,O₂ molecule.
