The cool atmosphere condenses the rising water vapor
and causes it to fall back to Earth
Water vapor does rise above other gases in the atmosphere, forming clouds and contributing to the greenhouse effect. However, it can't reach higher altitudes because it condenses and forms droplets or ice crystals, which eventually fall as precipitation.
Yes, molecules closer to the surface experience higher pressure due to the weight of the air above them, making them more densely packed. As you move higher in the atmosphere, there are fewer molecules above exerting pressure, resulting in lower density.

Atmospheric pressure
The layer of air above the Earth's surface is called the atmosphere. It is composed of various gases and extends several kilometers into space.
The layer of the atmosphere where gases do not maintain a uniform composition is the heterosphere. In the heterosphere, gases tend to separate into layers based on their molecular weights, with lighter gases being found at higher altitudes and heavier gases at lower altitudes.
That means that due to the presence of an atmosphere, and specific gases in the atmosphere, the average temperature on the planet is higher than it would have without an atmosphere - or without specific gases. Greenhouse gases, that increase the average temperature, include carbon dioxide (CO2) and methane (CH4).
The atmosphere above 80km (50 mi) and the homosphere where gases are stratified, with concentrations of the heavier gases decreasing more rapidly with altitude than concentrations of the lighter gases
More greenhouse gases trap more heat in the atmosphere, causing a global warming and climate change.
The layer of gases above Earth's surface is called the atmosphere. It is composed of various gases such as nitrogen, oxygen, carbon dioxide, and others. The atmosphere plays a crucial role in regulating the planet's temperature and protecting life on Earth from harmful solar radiation.
The greenhouse effect warms the gases in the atmosphere.
As you travel higher in Earth's atmosphere, the composition of gases changes in terms of their concentration. Oxygen, nitrogen, and argon are the most abundant gases in the lower atmosphere, while the percentage of oxygen decreases and other gases like helium and hydrogen become more prevalent in the upper atmosphere. The overall pressure also decreases with altitude, causing the air to become less dense.
