What does the atmosphere refer to?

1. The air we breathe

2. Water in the oceans and rivers

3. The land and soil

4. The stars and space

The correct answer is: The air we breathe

The atmosphere refers to the layer of gases that surrounds the Earth, which is critical for supporting life. It is made up of various gases, including oxygen and nitrogen, that are essential for respiration and weather patterns. This option correctly encapsulates the primary definition of the atmosphere, highlighting its role in providing the air that living organisms breathe. The atmosphere also plays a vital role in other processes, such as regulating temperature and protecting the planet from harmful solar radiation. The other options represent different components of the Earth's systems. Water bodies are referred to as the hydrosphere, land and soil fall under the geosphere, and stars and space pertain to the cosmos, none of which define the atmosphere itself.
