The Water Cycle PROPERTIES OF WATER • It is a POLAR MOLECULE: H atoms have a positive charge / O atoms have a negative charge • It sticks to itself: COHESION • It sticks to other substances: ADHESION • It can absorb large amounts of energy: SPECIFIC HEAT • It dissolves many things: UNIVERSAL SOLVENT WATER CYCLE • Water NEVER leaves the Earth. • It is constantly being CYCLED through the atmosphere, ocean, and land. • This process, driven by energy from the SUN. The Water Cycle EVAPORATION Sun heats up liquid water and changes it to a gas. Water vapor will rise up into the atmosphere TRANSPIRATION The process of evaporation from plants (it’s like plants sweating.) CONDENSATION As WATER VAPOR rises it will cool and become a LIQUID again. CLOUDS WILL FORM. PRECIPITATION When the water in the clouds gets too heavy, the water falls back to the earth. GROUNDWATER: When rain falls on the land, some of the water is absorbed into the ground. RUNOFF: Water that collects in rivers, streams, and oceans from precipitation.
