On earth, water can exist as a solid,a liquid, or a gas because "the Earth is at an ideal temperature due to its distance from the Sun".
<u>Option: </u>A
<u>Explanation:</u>
Water can occur at a specific temperature of 273.16 K and pressure of 611.2 Pa in three various states i.e. solid, liquid and gas, and this phase is considered to be triple point water. At such a temperature and pressure the water keeps moving from solid to liquid phase and vice versa.
The average global temperature of Earth at aphelion is about 4 degrees Fahrenheit, or 2.3 degrees Celsius higher than at perihelion. This results as the the Southern Hemisphere has more oceans while the Northern Hemisphere has more land, which make the heating up of the land easier and faster.
