GIVING BRAINLIEST PLZ NO FALSE ANSWERS Which statement best explains how Earth's magnetic field is generated? Earth's core spins slower than its crust Heat exchange between the mantle and crust The convection of heat within the mantle Rotation of liquid iron in the outer core

The convection of heat within the mantle Rotation of liquid iron in the outer core

Step-by-step explanation:

The electrical currents and convecting movements within the Earth's liquid core generate the planet's powerful magnetic field, which in turn drives the inner core in the way that can now be observed.

The answer "The convection of heat within the mantle" is incorrect. The correct answer is "Rotation of liquid iron in the outer core" For example this text from the lesson of the course I am taking right now states that "The earth's core has two regions, the inner core and outer core. The inner core of Earth is thought to be solid iron. The outer core is molten. As Earth spins on its axis, rotation of the liquid outer core generates Earth's magnetic field."

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
