They are trick questions.
They are a trick because you can obviously find the answer to them with even a basic search of my own past posts.
I am tired of answering the same questions over and over again, and having you guys play a police interrogation on me "Look, you answered that differently that time! You must be lying." Suit yourselves. No answer will be forthcoming.
Why is it so goddamn hard for you to answer two yes or no questions?

Most real questions do not have a yes or no answer that you can trap people in, they have what is called a nuance.
For example, does water always find its level? No, because that is the wrong phrase. Yes, water is always level. There is no such thing as a pool of water that mounds. You've just described a Dragon Quest slime there. But why is "find its level wrong?" Well it implies a wrong assumption that water is not level to start with, and has to seek out a level height. If this were so, waves could not happen. But waves move back and forth because there are things like springs and whirlpools. Water is level, but it flows in and out of areas based on conditions. Because by find, you are implying that there is some force leading it to be level, when no, it simply is level. So that's not a yes or no answer but a "mostly yes, I guess."
What about the second question? Well, if your question is "can you see a farther away object from a higher elevation?" Yes, you can. But you can also see a tall and wide object (such as a mountain) from a fairly low elevation. And you can see a high up object (such as a plane or balloon) from either elevation. The way you phrased this question is also awkward, because it essentially also asks "is there a longer 'box' of perspective from a higher vs lower elevation?" Unfortunately, the answer to that one appears to be no. Even though you can see objects that are like 100 miles away, this is effectively compressed perspective. That is to say, if at nearly sea level, three to five miles looks to be as far as you can see, your perspective looks to be the same width. Is that a yes answer? A no answer? Something else?
If your questions really are as simple as you claim they are, the answer is yes to both. But if they are trick questions, then the answer is one you'll need to read that paragraph to understand.
Ok, so you head on down to your nearest beach on a fine or cloudy day, but one where you can see that straight ass, level, motherfuckin horizon out to sea, where seawater meets sky. A gentle breeze has flattened the waves to the point the sea looks like a plane of glass laying flat.
We've all seen it, and I know you have, too, Bulma. Now, because water always finds it's level, the surface of that sea water in front of you to the horizon, is as perfectly level as it could possibly be.
So, you walk down to the water's edge, so the water line is equal to the undersides of your feet. Now, you look across at that horizon in front of you.
The horizon looks to be at your eye level, but it can't be can it? That horizon line out at sea, has to be the same level as the bottom of your feet. Your eye line is however high as it is, above the bottom of your feet.
This means, when you look at that physical horizon line out at sea, with the bottom of your feet at sea level, you must be looking ever so slightly down at that physical horizon line. In this instance, your eyeline cannot be the same as the surface of the seawater at the undersides of your feet level.
Do you catch my drift?
Now, let's say, for dramatic purposes you are 6'5 tall, and standing next to a 4' tall person doing the same observation and you both have equal eyesight tested and proved. As the 4' tall person's eyes are 2.5' lower to the ground than your eyes, it stands to reason the 4' tall person must see the horizon as closer, than you do. If two sets of eyes have the same eyesight, and distance of earth seen, is dictated by change in altitude and not eyesight capability, it stands to reason, that even though that seawater to horizon is perfectly level, it must also be curved.
In fact, if you went into that seawater and submerged yourself until your eyes, or more specifically pupils, were at the waterline, looking out at the horizon,, at long long last, your eyeline would be matching up with your physical horizon in front of you.
What have you got to say about that, Bulma? You agree water always finds it's level. You agree a person can see further with elevation.
Therefore that seawater must be curving downwards in front of you and the physical horizon as seen out at sea, is ever so slightly different, to the horizon line taught in perspective drawing. At ground level the differences are almost imperceptible, but the difference is there. In art and perspective drawing, you can get away with calling the eyeline the same as the horizon line.
But now you know better.
