1. How does the inner core affect all of the Earth's other layers?
Artist 52 [7]

Answer:

With the heavy inner core, the earth's orbit and rotation will remain stable over the long term, giving us day and night and summer and winter. ... These swirling convection currents result in the earth's magnetic field which keeps us properly oriented for travel, and shields earth from deadly cosmic rays

Explanation:

The inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC). Although the inner core is very hot, it is not liquid like the outer core.

Autonomic nervous system (ANS) is part of the peripheral nervous system (PNS) and is responsible for control of vital functions.

ANS  possesses three divisions, they are : Sympathetic nervous system (SYNS), parasympathetic nervous system and enteric plexus.  Sympathetic nervous system is responsible for flight and fight responses.

SYNS also performs such tasks as relaxing the bladder, speeding up heart rate, and dilating eye pupils.
