Never really thought about it before, but is there a reason for the distinction?

It does determine the rock type after settling. Lava becomes extrusive rocks (typically weaker because crystals have less time to form) were as magma because intrusive rocks (stronger like granite)

People called the stuff on the surface "lava"

Scientists called the stuff the crust floats on "magma"

Science needed to draw a line for when magma becomes lava, they chose when it reaches the surface

Calling the stuff lining your underground lair lava is about as bad as calling the Moon a planet

If you could float an island in the sky, would hovering over lava cause it to be magma? (Can you have lava in a large tunnel, or is that magma?)

Oceans are lava and ice is a mineral, if you stretch the definition enough
