causes the seasons
contains oxygen
provides warmth

blocks harmful energy from the sun

Explanation:

The atmosphere contains oxygen which is essential for life. It also provides warmth through the greenhouse effect. Additionally, it blocks harmful energy from the Sun like ultraviolet rays. Seasons are caused by the Earth's tilt and orbit, not directly by the atmosphere's composition in a way that makes Earth livable (though the atmosphere's gases play a role in climate which is related to seasons). Nutrients are mainly from the Earth's crust, biosphere, etc., not created by the atmosphere.

Answer:

blocks harmful energy from the Sun, provides warmth, contains oxygen
