Correct! Water from the Earth's surface moves in the air through a process called evaporation. Evaporation occurs when heat energy from the sun causes water molecules on the Earth's surface (such as lakes, rivers, or oceans) to gain enough energy to escape into the atmosphere in the form of water vapor. During evaporation, liquid water transforms into a gaseous state and rises into the Earth's atmosphere. So, in summary, the water from the Earth's surface moves in the air by undergoing evaporation and becomes water vapor in the Earth's atmosphere.
