The core is divided into two parts: the outer core and the inner core. The outer core is fluid, while the inner core is solid due to extreme pressure.

88. (b); The polar regions of Earth, also known as Earth’s frigid zones, are the regions of Earth surrounding its geographical poles i.e. the North and South Poles. These regions are dominated by Earth’s polar ice caps, the northern resting on the Arctic Ocean and the southern on the continent of Antarctica.
