, the world was made up of a single continent through most of geologic
time. That continent eventually separated and drifted apart, forming
into the seven continents we have today. The first comprehensive theory
of continental drift was suggested by the German meteorologist Alfred Wegener
in 1912. The hypothesis asserts that the continents consist of lighter
rocks that rest on heavier crustal material—similar to the manner in
which icebergs float on water. Wegener contended that the relative
positions of the continents are not rigidly fixed but are slowly
moving—at a rate of about one yard per century. 
        
             
        
        
        
A state is in a country, a country is in a continent. The main difference is size. a state can be really populated, but a country is more populated. a continent is even more populated then that. Hope this helps
 
        
             
        
        
        
Hello!
In order for an animal to be a vertebrate, it must have a backbone. As can clearly be seen in any image of a sponge, it is a highly asymmetrical simple animal and does not have a backbone. Therefore, a breadcrumb sponge is not a vertebrate, or is an invertebrate.
I hope this helped!
