When vectors are allocated, do they use memory on the heap or the stack?

Are all of the following statements true?

vector<Type> vect; //allocates vect on stack and each of the Type (using std::allocator) also will be on the stack

vector<Type> *vect = new vector<Type>; //allocates vect on heap and each of the Type will be allocated on stack

vector<Type*> vect; //vect will be on stack and Type* will be on heap. 

How is the memory allocated internally for Type in a vector or any other STL container?
