Magnetic dip is the angle between the horizontal and Earth’s magnetic field. A compass needle, for example, will not point north and south, but will also have a dip. It tends to dip at an angle toward the Earth (and to the sky). The dip is generally greater toward the pole. At various locations close to the equator (but not exactly at the equator), the dip is zero.
Magnetic dip as observed on various locations on Earth can only happen if the Earth is spherical.

An ice shelf is a thick floating platform of ice. Ice shelves are found not only in Antarctica but also in Greenland, Canada, and Russia in the north polar region.
Flat-Earthers often show off pictures of an ice shelf as ‘proof’ of the existence of the mythical giant ice wall surrounding the Earth. They are wrong.

James Cook made three significant voyages to the Pacific Ocean. Flat-Earthers often made their case with his second voyage. In this voyage, James Cook was tasked to find the hypothetical continent, the Terra Australis, that was predicted to be around the southern Pacific Ocean. In his second voyage, James Cook proved no such continent exists.
Flat-Earthers often take the second voyage of James Cook as ‘proof’ that Antarctica is not a continent, but a massive landmass encircling the flat-Earth. Their ‘proof’ is that Cook traveled more than 60000 miles, and 60000 miles is much farther than the circumference of Antarctica. They are wrong.

The majority of the flat Earth models place the Arctic Ocean in the middle of the flat Earth, and Antarctica at the edge of it. The Sun is pictured floating and moving in a circle above it. The Sun’s area of light is limited to a circular area below it, like a spotlight.
A problem: a simple observation of day and night cycles in a different area of the world cannot be explained in this flat Earth model.

In photography, the starburst effect gives the illusion of light rays from strong light sources in an image. The effect happens when the lens’ aperture is not a perfect circle, and it gets more pronounced under narrower aperture.
Flat-Earthers often find themselves looking for any peculiarity —no matter how small or unbelievable— in order to discredit any picture they deem unacceptable to their misguided causes. One of this peculiarity is the starburst effect.

An ice dome is one of many forms a glacier can take. It is an upright ice surface in the higher altitude portions of an ice cap or an ice sheet. There are many such features found on icy terrain. And Antarctica is no exception.
When an ice dome gets mentioned, flat-Earthers often confuse it with the mythical dome enclosing the Earth as described in most flat Earth model. No such dome actually exists.

Flat-Earthers think there hasn’t been anyone who has circumnavigated the Earth by traversing both the north pole and south pole in the process. All we have are explorers who have circumnavigated the Earth to the east or west, parallel to the equator; explorers like James Cook or Ferdinand Magellan. They don’t really have the choice, because if polar circumnavigation is possible, then the flat-Earth assumption falls flat.
But, like a lot of assumption in the flat-Earth community, it is simply not true. There are in fact many people who have done a polar circumnavigation, and the information can be easily found on the Internet.

Some flat-Earthers claim there is no non-stop long-haul flights between two locations in the southern hemisphere. Flights need to make a stop in a location in the northern hemisphere because the distance will be too far and such flight will traverse the northern hemisphere, or more accurately, the center of the Earth according to their model.

Midnight Sun is a natural phenomenon when the Sun remains visible at midnight. This occurs in the summer months in the north of Arctic Circle, and south of the Antarctic Circle.
The apparent motion of the Sun in both polar regions is different. In the north polar region, the Sun moves from left to right. On the other hand, in Antarctica, the Sun moves from right to left. It is not difficult to imagine that we all reside on a rotating sphere. There’s simply no other explanation.

According most flat earthers, there’s no such thing as the continent of Antarctica. In their imagination, Antarctica is not a continent, but a long ice wall enclosing the Earth. Without having anything to prove that assumption, they look anywhere for any quote they can mine and stumbled into this quote by Admiral Byrd:
“Strangely enough, there is left in the world today, an area as big as the United States, that’s never been seen by a human being. And that’s beyond the pole, on the other side of the south pole from Little America.”
