Was Terra built on Cosmos?

Could you clarify for me if Terra was indeed constructed upon the Cosmos platform? I've been reading about blockchain technology and its various applications, and I'm particularly interested in understanding the relationship between these two projects. I understand that Cosmos is a scalable blockchain interoperability solution, and I'm wondering if Terra leveraged this functionality in its design. If so, how does this integration enhance Terra's capabilities? It would be greatly appreciated if you could elaborate on this matter, as it would help me better grasp the intricacies of the cryptocurrency and finance landscape.
