- The oceans are located on earth
- The oceans contain liquid water
- So, liquid water is located on earth

- Liquid water is located on earth
- Water is in the liquid state , called liquid water , for temperatures between 273 / 32 / 0 and 373 / 212 / 100 k / f / c
- So, water in the liquid state is located on earth

- Arctic environments contain ice
- Arctic environments are located on earth
- Therefore, ice is located on earth

- Ice is located on earth
- Water is in the solid state , called ice , for temperatures between 0 / -459 / -273 and 273 / 32 / 0 k / f / c
- Therefore, water in the solid state is located on earth

- Earth's atmosphere contains water vapor
- Earth's atmosphere is located on earth
- So, water vapor is located on earth

- Water vapor is located on earth
- Water is in the gas state , called water vapor / steam , for temperatures between 373 / 212 / 100 and 100000000000 k / f / c
- Hence, water in the gas state is located on earth

- Water in the liquid state is located on earth
- Water in the solid state is located on earth
- Water in the gas state is located on earth
- Hence, water in the liquid, solid, and gas state is located on earth

Therefore, water in the liquid, solid, and gas state is located on earth
