Hydrosphere
No. All water on Earth forms the hydrosphere. The biosphere is all life on Earth.
Rain, sleet and snow are all forms of water at different stages. Stages that are governed by the temperature that affects the rain as it falls to earth.
The agents of weathering include water, wind, sun, ice, frost, and plants and animals. All these different agents work on rocks and make changes to them over years.
All water on the planet Earth, in all three forms: ice in the poles, liquid water in the oceans, lakes and rivers around the world, and finally the water vapor in the atmosphere.
It's all from the water cycle. First water vapor rises up into the sky and forms clouds. When water droplets get too heavy in the clouds they precipitate. So to answer your question clouds and water
All rivers have a source which id the beginning of the river
Hardest question ever
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
Water exists in all physical states. Water exist as vapors, snow and droplets.
The word "ice" is a concrete noun. A concrete noun is a word for something that can be experienced by any of the five physical senses; something that can be seen, heard, smelled, tasted, or touched.All forms of water are concrete nouns because water is made up of the physical elements hydrogen and oxygen; ice, water, and steam or vapor are physical things.
Mass and thermodynamic temperature.

Solids, liquids, gases, and plasmas are all physical forms. Consider ice, water, and steam: you can see and feel all three states of H2O. If refering to a state in which the substance does not change shapes, it would be a solid.
This is a physical change. Water can take on 3 forms, ice, gas, and liquid. These would be changes in state. Tearing, scratching, crushing, change in state, are all physical changes. Chemical changes must change the substance, not just the appearance. (i.e. Burning fire into ashes, fireworks exploding...)
