Question
What two important elements constitute the earth's inner most core?
a. Magma and lava
b. Potassium and Magnesium
c. Granite and basalt
d. Nickel and Iron
Solution
d. Nickel and Iron
Explanation:
The Earth's innermost core is primarily composed of two elements: nickel and iron.
a. Magma and lava - These are not elements, but rather molten rock. They are found in the Earth's mantle and crust, not the core.
b. Potassium and Magnesium - These elements are found throughout the Earth's crust, but they are not the primary constituents of the core.
c. Granite and basalt - These are types of rock, not elements. They are found in the Earth's crust, not the core.
d. Nickel and Iron - These are the two primary elements that make up the Earth's inner core. The core is believed to be composed mostly of an iron-nickel alloy.
