can somebody please explain why the deeper you dive into the sea, the pressure will increase? and where does that pressure come from?

Pressure increases because of the weight above you.
Standing on the beach, you have 14 pounds of air pushing down on every square inch of your body.
If you dive to 30 feet, you have that same 14 pounds of air pushing down on you, but also the weight of a 1-square-inch, 30-foot-long column of water pressing down on the same square inch of your head. THis happens to be another 14 pounds. If you dive another 30 feet, you add another 14 pounds to that column of water pressing down on each square inch of your head.
Picture lying on the sand and having people pour sand OVER you. As they pour more and more sand, you feel more and more pressure. Same concept.

It's the weight of water above you.
Pressure increases by 1 bar (1 atmosphere) for every 10 metres of depth.

Imagine a column of water in your front yard one inch square extending 10 feet up in the air. How much do you think that would weigh. How much pressure would that column of water apply if you lifted it up and put it on your head?

It comes from the weight of all the water above you pressing down onto you. Just like how if you hold a bottle of water in your hand it presses down on your hand.
