Acommon visual behavior is the âhead jerk.â This motion is generally observedwhen an individual otter approaches a raft of sea otters. The approaching otternoses and sniffs the other otters while jerking its head from side to side.
Axis tilt is the vertical angle at which the ball rotates. Axis tilt is what is commonly known as spin. Axis tilt is determined by the position of the thumb during the release. If the hand turns too early, the thumb exits on top of the ball. Bowlers with a high degree of axis tilt will be able to see the top of their hand during the release and follow through.
Obliquity: Obliquity refers to the axial tilt of the Earth. The Earth is constantly spinning on its axis, which today is tilted to an angle of 23.4 degrees. Over a period of 41,000 years this the degree of tilt varies between 22 and 24.5 degrees.This tilt influences the Claudia distribution of solar energy.he Earth is constantly spinning on its axis, which today is tilted to an angle of 23.4 degrees.
