The Coriolis force is a force that acts on objects that are in motion within a rotating frame of reference. Because the Earth is a rotating sphere, an object traveling unattached to Earth’s surface is affected by the Coriolis force, depending on its speed and direction, as well as its latitude on Earth’s surface.
The rotating motion of the Earth causes the different parts of Earth’s surface to have different linear speeds, depending on its distance from the Earth’s rotational axis. An object moving from a location to another with a different linear speed will be affected by the Coriolis force because the motion of the object is now being observed from another location with a different linear speed/direction relative to Earth’s rotational axis.

Red Bull Stratos was a high-altitude diving project involving Felix Baumgartner. In 2012, Felix Baumgartner flew 39 km (24 mi) into the stratosphere in a helium balloon before free falling in a pressure suit and then parachuting to Earth. Flat-Earthers invented various excuses to dismiss the resulting footage from the project.

The Foucault Pendulum is an experiment to demonstrate Earth’s rotation, named after French physicist Léon Foucault. The Foucault pendulum is the first simple and direct evidence of the Earth’s rotation. It is a straightforward experiment: a huge pendulum is allowed to swing throughout the day, and it will slowly rotate because of Earth’s rotation.
For any flat-Earthers, the Foucault pendulum is one of the facts that must be discredited. They would invent various “explanations” to reject the conclusion of the experiment. They are wrong. Anyone is free to repeat the experiment, and when done correctly, it will result in a consistent result and in line with expectations.

When a sniper shoots a long-range target, if he is in the northern hemisphere, the bullet is deflected to the right. Conversely, if he is in the southern hemisphere, the bullet is deflected to the left.
The phenomenon occurs because the Earth is spherical and rotating.

A cyclone or hurricane rotates in a different direction depending on which hemisphere it occurs. A cyclone rotates counterclockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere.
The phenomenon happens because of the Coriolis effect, which in turn occurs because the Earth is spherical and rotating.
