Which of these is NOT true about the outer core? Question 4 options: It is mostly made up of iron and nickel. It is mostly liquid. It has a higher temperature than the inner core. atoms within it form a powerful magnetic field.

Of the mentioned statements the incorrect statement is that it has a higher temperature than the inner core.

Explanation:

Both the outer and the inner core are formed of identical constituents chemically, that is, both are formed majorly of iron, with some quantity of nickel and some other chemical constituents. The difference is that the inner core is solid, while the outer core is liquid in the state. As one goes deeper, both the pressure and the temperature because of the weight of the overlying rock gets an increase.

The outer core is liquid in the state as the temperature is so much that the melting of iron takes place. However, the inner core is hotter in comparison to the outer core, but it is solid as the pressure is so much that it makes the atoms of the constituents to come so close to each other that they turn solid.

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

the answer is c i believe
