sophia was studying with maalik about the layers of the earth. they were given several different statements about the layers. which statement about the layers would they identify as correct? the outer core is less than 70 km in thickness. the crust assists in forming earths magnetic field. the mantle is denser than the crust. pressure increases when moving from the core to the crust.
Answer
Brief Explanations:
- The outer - core is about 2300 km thick, so the first statement is incorrect.
- Earth's magnetic field is mainly generated by the movement of molten iron in the outer - core, not the crust, so the second statement is incorrect.
- The mantle is denser than the crust because it is under higher pressure and has different chemical compositions. This statement is correct.
- Pressure increases as we move from the crust to the core, not the other way around, so the fourth statement is incorrect.
Answer:
The mantle is denser than the crust.
