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.

Seawater salinity does not have a correlation to tides. Just because seawater has a higher salinity than lake water, it does not mean salinity causes tide.
Some flat-Earthers claim tides are the result of salinity. They are wrong. There are bodies of water that do not have tides as large as seawater, but their salinity is much higher than seawater.

Some flat-Earthers mentioned the fact that graviton —the mediating particle of gravitation— is ‘not yet observed’. They took this fact as ‘proof’ that gravity does not exist.
Often they would triumphantly show us screenshots of the table of fundamental particles they took from Wikipedia and other sources. In the ‘gravitation’ column, they would point out its mediating particle has not been observed yet. And they would conclude that scientists are aware gravity does not exist, and we all have been lied to.
Obviously, they are wrong on all accounts.
