Answer: The given statement is true.
Explanation:
When solid state of water changes directly into vapor state then this process is known as sublimation.
For example, when dry ice is placed at room temperature then it converts into vapor state without undergoing liquid state.
Also when we apply very high pressure or temperature at the solid state of water, it will change directly into vapor state.
Therefore, the statement ice does not need to melt into liquid water before it can return to the atmosphere as water vapor is true.
