That's known as "perspective".
If you're on the ISS - 205-270 miles above the Earth's surface - and take a picture, the majority of your viewfinder will be filled with whatever ground you're directly above. Even a relatively small country like the UK will fill most of your view:

A continent like Africa fills just about your entire field of view. Actually, just a small part of it does:

The famous Blue Marble image was taken from 18,000 miles from the Earth's surface - and from that perspective, with Earth itself taking up a smaller slice of your field of view, the majority of Africa is now visible:

The continent hasn't changed size or shape - Africa doesn't
actually take up half the planet, like it appears to from the ISS, or even a third of one face of the planet, like it seems in Blue Marble - you're just viewing it from a different perspective. In "Earthrise", taken aboard Apollo 8 as it orbited the moon, Africa is visible to the lower end of the ball (and South America to the upper end) - and Africa looks even smaller compared to the size of the planet than it does in Blue Marble:

But then it would, because the moon is an average of about 239,000 miles from Earth - more than 10x further than the Blue Marble image, so while the planet is smaller in your field of view, you're seeing more of its surface - and objects on that surface, like continents, take up proportionally less space.
It doesn't take a genius to work out - if you stood in the middle of the Sahara Desert then you'd only be viewing the tiniest proportion of the continent's surface but it would fill the entirety of your view below the horizon for 360 degrees.
What it isn't is an "inconsistency" - just a simple effect of what happens when you move closer to or further away from an object.
Then why not open your eyes to the correct information, rather than the baseless drivel spouted by flat-earthers?
