'The earth is cooling and shrinking, which causes the crust to crack as it shrinks and that's why we still have active volcanoes.'
The concept here is that since the earth cools, contracts and shrinks ... the crust cracks and then lava squirts out through the cracks! In this "theory", there is NO heat engine in the core of the earth; it's still just cooling over 4 billion years ... like hot coffee would cool in a thermos and be pleasantly warm, even 4 billion years later. How that could possibly be possible since there's no particularly good insulating value in dirt ... is never explained by the "scientists" who, nevertheless, push this theory.
The earth is a ball. The entire earth (ostensibly) started OUT as a ball of gas which cooled and formed a ball of molten material ... and then the crust formed around a still-molten core.
Well, here's the problem with that theory ...
If a ball of red hot material is cooling and a solid crust forms on the surface the inside of the cooling ball becomes smaller which only causes the round crust -like an eggshell- to become COMPRESSED. You would get a "vacuum" inside of the ball which would SUCK through any cracks in the crust ... not eject material through the cracks.
The core can't be cooling when/where lava comes out through the cracks. Cracks can't form from shrinking but they CAN form from internal pressure.
