Life as we know it requires both water and air. Certainly human beings cannot live without those things. So from our point of view, it is very convenient to be living on a planet that has both an atmosphere and a hydrosphere. It would be much harder to live on a planet such as Mercury, which has neither of those things.

The amount of water vapor in the air changes significantly with location and temperature. so a listing of percentage of gasses in the atmosphere would be different depending on how much water was in the air sampled. That would not be useful, because the other gases in the atmosphere do not change all that much. So it is more helpful to describe the making of the atmosphere as dry air (containing no moisture) and then adjust if needed for the humidity at any one place and time.
Weather refers to the temporary conditions of the atmosphere such as the temperature, rainfall or wind, and weather changes from time to time. Climate refers to the variety of weather conditions normally experienced on the average and it changes from place to place.
The lower atmosphere is bound to Earth by gravity, which keeps gases such as nitrogen, oxygen, and carbon dioxide close to the planet's surface. The hydrosphere, which includes water bodies such as oceans, lakes, and rivers, is also held in place by gravity.
the difference is that the hydrosphere is made up of all the water on earth.The most obvious form of water is its liquid state.The hydrosphere also includes water in its vapor form in the atmosphere and its frozen,solid form in glaciers.The Water in Earth's oceans,sea,rivers,lakes,glaciers,and atmosphere is all part of the hydrosphere.And the Atmosphere is the layer of mixed gases that surrounds Earth.All weather events,such as tornadoes,hurricane,storms take place in the atmosphere.Also the atmosphere keeps earth from becoming too hot or too cold, and protects all life-forms from the Sun's harmful rays.

That is called weather. Weather refers to the specific atmospheric conditions, such as temperature, humidity, precipitation, and wind, that occur at a particular time and place due to the interaction of the atmosphere and the hydrosphere.
The different spheres present on earth are1.Lithosphere (solid portion of the earth)2.Hydrosphere (liquid portion of the earth)3.Atmosphere (air around the earth) 4.Biosphere (the place where all the above spheres meet thus enabling life)
The atmosphere of the Earth is held in place by Earth's gravity.
Weather is the condition of Earth's atmosphere at a particular time and place.
The amount of water vapor in the atmosphere varies from place to place. Humidity is the term used to describe the amount of water vapor in the atmosphere.
The Earth is the only planet known to have liquid water on its surface, which is essential for supporting life as we know it. Earth also has a unique atmosphere that contains the right mix of gases to sustain life and protect us from harmful cosmic radiation. Additionally, Earth's magnetic field helps shield the planet from solar wind and cosmic rays, making it a hospitable place for life to thrive.

The condition of the earth's atmosphere at a particular place is called "Weather".
