Although both are methods by which liquid water transitions into a gas, evaporation describes the process in which heat changes standing water into water vapor, while transpiration refers to the process plants undertake that draws water from the ground and releases it into the air.Know More
Evaporation and transpiration are both parts of the water cycle, in which liquid water turns into water vapor and joins the other gases in the atmosphere. While water molecules sublimate into the air under normal circumstances, increased heat speeds up the process. Evaporation occurs when enough heat is present to break the molecular bonds holding water molecules together. This allows the water to become a gas and float up into the atmosphere.
Transpiration occurs as plants pump water from the ground, up through their roots and stem, and out of tiny holes in the leaves, called stomas. Despite the world’s numerous plants and trees, transpiration is responsible for only about 10 percent of the liquid water that transitions into water vapor. The evaporation of liquid water in ponds, lakes, rivers and oceans is responsible for the other 90 percent of the water vapor in the atmosphere.
Evaporation requires a net input of energy, which creates a cooling effect on the local environment. This is why sweat cools humans, and trees help to cool humans and habitats.Learn more about Erosion & Weathering
Water that has been heated to the point that it transforms into its gas form is simply known as water vapor, or sometimes simply as vapor. Water vapor, in its own pure form, is invisible, unlike the water and its solid form, ice.Full Answer >
A sinkhole is the result of the surface layer of the ground collapsing, causing a depression to form beneath. Sinkholes can range in size from tiny to massive, anywhere between only a few feet in diameter to miles across. Sinkholes are found all over the earth, and while some take years to develop, others form rapidly.Full Answer >
Sinkholes are depressions or holes that form on the Earth's surface when the ground below erodes away. Sinkholes often indicate the presence of tunnels or caverns below the ground.Full Answer >
A water-cooled air conditioner takes stress off the compressor by using water vapor to remove heat from the refrigerant. Commercial buildings typically use this technology in their split-system air conditioning systems, but residential units are also available. Water-cooled air conditioners are usually towers and are often referred to as chillers.Full Answer >
