Plants use their roots to get oxygen. Oxygen is dissolved in water, and there's also air pockets in their grow medium to provide a source of oxygen. When you water your plants too often, its roots are sitting in stagnant water which no longer has any oxygen left.
Which point(s) in the water cycle below best illustrate(s) water changing to a gas, and which term(s) could describe it? Is it.. 1; sublimation & evaporation. 2; evaporation only.
Water existing as a gas is called water vapor, water as a liquid we generally just refer to as water, and water as a solid is called ice. The changes from a solid to liquid to a gas or a gas to a liquid to a solid are called phase changes.When substances such as water change phase, its physical properties change, but not its chemical properties (water is always H 2 0 - 2 hydrogen atoms and 1 oxygen atom).olid to Gas: When water changes from a solid (ice) to a gas (water vapor) it goes through the process of sublimation. Liquid to Gas: When water changes from liquid water to water vapor (has) it goes through the process of evaporation.
