Key Differences
The atmosphere, a complex layer of gases surrounding Earth, plays a pivotal role in protecting life by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night. In contrast, the hydrosphere includes all of Earth's water bodies, such as oceans, seas, rivers, lakes, and water vapor in the atmosphere, integral to the water cycle and supporting diverse ecosystems.
While the atmosphere consists mainly of nitrogen (78%) and oxygen (21%), with traces of other gases like argon, carbon dioxide, and water vapor, the hydrosphere is predominantly water in liquid form, with significant portions in solid form as ice (polar ice caps, glaciers) and a small percentage as water vapor. These two spheres interact closely, with the hydrosphere contributing to atmospheric humidity and the atmosphere influencing weather and climate patterns over water bodies.
The atmosphere is divided into several layers based on temperature gradients, including the troposphere (where weather occurs), stratosphere, mesosphere, thermosphere, and exosphere. The hydrosphere, however, is categorized by the type of water body and its location, including surface water (oceans, lakes, rivers) and groundwater.
Atmospheric processes, such as the circulation of air masses and the water cycle, directly impact weather and climate patterns, affecting human life and ecosystems. The hydrosphere plays a critical role in regulating Earth's climate through the storage and distribution of heat, with oceans absorbing a significant amount of solar radiation and distributing heat globally via currents.
Interactions between the atmosphere and hydrosphere are fundamental to Earth's environmental systems. For instance, the exchange of heat and moisture between the ocean and atmosphere drives weather events like hurricanes and monsoons, while the absorption of CO2 by oceans influences atmospheric composition and climate change.

Atmosphere
An atmosphere (from the greek words ἀτμός (atmos), meaning 'vapour', and σφαῖρα (sphaira), meaning 'ball' or 'sphere') is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body. An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low.
Hydrosphere
The hydrosphere (from Greek ὕδωρ hydōr, "water" and σφαῖρα sphaira, "sphere") is the combined mass of water found on, under, and above the surface of a planet, minor planet, or natural satellite. Although Earth's hydrosphere has been around for about 4 billion years, it continues to change in shape.
