Question

the temperature at which water freezes enables water to exist in which two forms on earth?
○ freshwater rivers and saltwater oceans
○ liquid oceans and solid glaciers
○ atmospheric vapor and cloud droplets
○ water in soil and water in plants

Explanation:

The question is about the forms of water enabled by its freezing temperature. We analyze each option:

• "freshwater rivers and saltwater oceans" refers to water salinity types, not forms (liquid/solid/gas) related to freezing.
• "liquid oceans and solid glaciers": Oceans are liquid water, glaciers are solid (ice) formed due to water freezing. This matches the effect of water's freezing temperature on its forms.
• "atmospheric vapor and cloud droplets" are both gaseous/liquid forms, not related to freezing into solid.
• "water in soil and water in plants" are about water location, not forms from freezing.

Answer:

B. liquid oceans and solid glaciers
