### Mercury
- **Biosphere:** No known biosphere; extreme temperatures and lack of atmosphere prevent the existence of life.
- **Hydrosphere:** No significant bodies of water; surface is dry with some transient ice in shadowed craters.
- **Geosphere:** Rocky planet with a heavily cratered surface, large metallic core, and a relatively thin silicate mantle.
- **Atmosphere:** Extremely thin atmosphere composed mostly of oxygen, sodium, hydrogen, helium, and potassium; unable to retain heat.
### Venus
- **Biosphere:** No known biosphere; surface conditions are extremely hostile to life due to high temperatures and pressure.
- **Hydrosphere:** Very little water; possibly once had oceans, but now surface dominated by volcanic plains and thick clouds of sulfuric acid.
- **Geosphere:** Rocky planet with a variety of geological features including volcanoes, mountains, and large lava plains.
- **Atmosphere:** Dense atmosphere primarily of carbon dioxide, with clouds of sulfuric acid; creates a strong greenhouse effect resulting in high surface temperatures.
### Earth
- **Biosphere:** Rich biosphere with diverse ecosystems supporting a wide variety of life forms.
- **Hydrosphere:** Abundant water covering about 71% of the surface; includes oceans, rivers, lakes, and ice caps.
- **Geosphere:** Composed of a solid inner core, liquid outer core, mantle, and crust; features mountains, valleys, and tectonic activity.
- **Atmosphere:** Nitrogen (78%) and oxygen (21%) dominate; protects life, regulates temperature, and supports weather patterns.
### Mars
- **Biosphere:** No confirmed biosphere; evidence suggests past microbial life may have existed but current conditions are harsh.
- **Hydrosphere:** Presence of water in the form of ice and possibly salty liquid water brines; ancient riverbeds indicate past water flow.
- **Geosphere:** Rocky surface with the largest volcano in the solar system (Olympus Mons) and deep canyons (Valles Marineris); features suggest a history of geological activity.
- **Atmosphere:** Thin atmosphere composed mainly of carbon dioxide, with trace amounts of nitrogen and argon; insufficient to support human life.
