The Earth's core is composed mainly of iron and nickel.
-
True
-
False
Correct Answer
A. TrueExplanation
The Earth's core is divided into two parts: the inner core and the outer core. The inner core is solid and composed mostly of iron with a temperature of around 5,200° Celsius (9,392° Fahrenheit). The outer core is liquid and composed of a nickel-iron alloy. The Earth's core plays a crucial role in generating the planet's magnetic field, which protects us from harmful solar radiation.Rate this question:
