Why will water rise higher in a smaller tube than in a longer tube?

Assuming it has a concave meniscuss, which most liquirds do, the surface tension causes an upward force, which only has any real effect in a small tube. Mercury is the oppostite, as it has a convex meniscess(shape where the liquid meets the air). Both of these assume a tube that is open at the top; if it is closed, the situation changes.

It depends on what you mean by larger or smaller. The ridge is much longer than the Himalayas, but does not rise as high above the surrounding terrain.
