Alyssa is taking a walk on a nature path near her neighborhood. she carries a compass with her. as she walks along the path, she notices the needle on the compass is occasionally deflected from its original position. if she has not changed the direction she is walking, what is most likely causing the occasional shift in the needle?

Change of Direction (Movement)

Explanation:

She might be walking towards Northern position before she changed her direction, what causes the compass needle to shift is because of the magnet inside the compass points towards north pole and its attracted to the south pole.

giant impact theory - the moon was formed from the collision between earth and another mars-sized body.

colliding planetesimals hypothesis - the moon was formed from the same cloud of material as earth.

capture hypothesis - the moon was locked into orbit by earths gravity as it was passing by it.

accretion hypothesis - the moon was formed from collisions and combining of planetesimals.

i think this is right, if not and you know better let me know.
