Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A very large pendulum can be used to investigate motion and forces on a planetary scale. When the pendulum is first set in motion, it will swing back and forth along the same line of swing. After a few hours, the line of the swing of the pendulum will change direction. What MOST likely affects the line of swing of the pendulum?
A
the rotation of Earth on its axis
B
the revolution of Earth around the Sun
C
the gravitational pull of the Sun on Earth
D
the gravitational pull of the Moon on Earth
Explanation: 

Detailed explanation-1: -When the pendulum is first set in motion, it will swing back and forth along the same line of swing. After a few hours, the line of the swing of the pendulum will change direction. What most likely affects the line of swing of the pendulum? The rotation of Earth on the axis.

Detailed explanation-2: -The most apparent evidence is of course the glacial drift itself. Glacial drift refers to the rock material ground up and transported by a glacier and deposited by or from the ice (till) or in water derived from the melting of ice (outwash or lake sediment).

Detailed explanation-3: -Which statement best describes the greatest impact that the ozone layer has had on the geosphere? the presence of the ozone layer was necessary for the formation of organic sedimentary rocks.

Detailed explanation-4: -The easiest way to think about this is to imagine the two extremes: zero tilt and 90°. If our planet’s axis had zero tilt, we would experience no seasons – no winter or summer, no change in temperature throughout the year.

Detailed explanation-5: -Because each swing of a pendulum takes it from a point farther from the equator to a point nearer to the equator and vice versa, and the velocities at these points differ, the path of the pendulum is subtly distorted with every swing, gradually torqued away from its original orientation.
