Slab Foundation Crack What Could Be The Cause Of Cracks Between Inside Foundation Slab And The Wall?

What could be the cause of cracks between inside foundation slab and the wall? - slab foundation crack

I live in Houston and yesterday's rain flooded my studies because of the cracks between the plate and the inner wall. I think the problem has been the rapid rise of water near my house on the ground came under the foundation. I closed the cracks in the interior, but not sure if that solves the real problem, but you do not know what the real problem. If I think someone in my garden or foundation? I need help on this point.
