Coastines on opposite continents appear to fit like puzzle pieces, indicating that they were once joined.
Convection is a process which transfers the heat between the temperatures when fluid (i.e. liquid or gas) is in motion. Due to the presence of heat source, water temperature increases and also it will become less dense and rise. Hot air is less dense than cold. When air rises higher in the atmosphere its pressure gets down and it becomes colder.
I might be wrong but I think the answer is
Continental deflection
Steps which must be taken to improve environmental quality in Eastern Europe are:
Data collection, enforcement, and international policy development
