List the four properties of water that allows Earth
to sustain such abundant life.

The main property of water that helps sustain life on earth is that water has. a high specific heat. This causes water to gain heat very slowly.

Specific heat is the amount of heat required to raise the temperature of water by one degree Celsius. Specific heat of water is 4, 186 joules /gram Celsius, and it is higher than that of a metal and of any other common substance.

Due to this, water resists tendency to evaporate or to vaporize and  therefore plays the crucial role of stabilizing temperatures on earth for terrestrial life and at the same time enabling aquatic organisms to maintain relatively constant internal temperatures.
