water cycle, also called hydrologic cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.
What is the process of condensation and precipitation?
Condensation is the process where water vapor (a gas) changes into water droplets (a liquid). … Precipitation is water that falls to the earth. Most precipitation falls as rain but includes snow, sleet, drizzle, and hail.
What is precipitation process?
Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth. … These ice crystals then fall to the Earth as snow, hail, or rain, depending on the temperature within the cloud and at the Earth’s surface.
What is the process called when water evaporates?
Credit: Alan Cressler, USGS. Evaporation is the process by which water changes from a liquid to a gas or vapor.What is water cycle process?
The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
What is the main process by which water moves from land to the atmosphere?
Evaporation of water from the land happens directly from lakes, puddles, and other surface water. Also, water also makes its way into the atmosphere via a process called transpiration in which plants release water into the air from their leaves that was pulled up from the soil through roots.
What is evaporation and condensation?
Condensation is the change from a vapor to a condensed state (solid or liquid). Evaporation is the change of a liquid to a gas. The Microscopic View of Condensation. Microscopic view of a gas.
What kind of change is involved in evaporation process?
Evaporation, like melting or freezing, is an example of a phase change—a change from one physical form of a substance to another. During evaporation, energetic molecules leave the liquid phase, which lowers the average energy of the remaining liquid molecules.How evaporation condensation and precipitation are essential for the water cycle?
by evaporation water goes into the air and by condensation process water vapours changes to liquid and through precipitation(in the form of rain,snow,hail etc.) process water comes back to the earth . so they play a very essential role in completing the water cycle.
Is evaporation an endothermic process?Molecules that are evaporating are absorbing heat. Because the molecules are absorbing heat, evaporation is called endothermic.
Article first time published onWhy is the process of evaporation occurs only at the surface?
So, after extreme cooling liquid cannot convert into gas or vapour. Evaporation is a type of vaporization. During evaporation liquid molecules from the surface of the liquid evaporates into the gas phase. So, evaporation takes place only from the surface, so evaporation is a surface phenomenon.
What are forms of condensation?
- Dew: The deposition of water vapour in the form of tiny droplets on the colder bodies by condensation is known as dew. …

What are the four types of precipitation processes?
Precipitation (Water Falling from the Sky) There are many different types of precipitation —rain, snow, hail, and sleet for example—yet they all have a few things in common. They all come from clouds. They are all forms of water that fall from the sky.
What are the 4 main processes of the water cycle?
There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam. The water vapour or steam leaves the river, lake or ocean and goes into the air.
What is condensation in water cycle?
Condensation is the process by which water vapor in the air is changed into liquid water. … These clouds may produce precipitation, which is the primary route for water to return to the Earth’s surface within the water cycle. Condensation is the opposite of evaporation.
What are the 5 processes of the water cycle?
There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration.
What are the 7 processes of the water cycle?
The water cycle processes involve evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage. Evaporation takes place when water changes from its liquid state to vapor or gaseous state.
How are the processes of evaporation and condensation similar?
The terms evaporation and condensation are both steps in the water cycle. Evaporation occurs when a liquid (water in the water cycle) is heated and changes from a liquid to a gas. Condensation occurs when water vapor cools and changes from a gas to a liquid.
How is the process of evaporation different from condensation explain with an example?
Difference Between Evaporation and CondensationEvaporationCondensationBy definition, evaporation is a process where water changes into vapour.Condensation is the opposite process where water vapour is converted to tiny droplets of water.
What is condensation short answer?
Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
How does the water cycle help in the formation of bodies of water on Earth?
Energy from the sun helped power the water cycle and Earth’s gravity kept water in the atmosphere from leaving the planet. … When warmed by the sun, water on the surface of oceans and freshwater bodies evaporates, forming a vapor. Water vapor rises into the atmosphere, where it condenses, forming clouds.
What type of change occur when water changes from solid to a liquid?
ABWhat type of change occurs when water changes from solid to a liquida phase change a physical change and irreversible change both A and theThe phase change that is the reverse of condensation issublimation
Is evaporation of water a physical or chemical change?
Melting, evaporation and condensation are examples of physical change, or change of state, and are distinct from changes that cause new materials to form through a chemical reaction.
Is condensation an endothermic process?
Condensation is an exothermic reaction. This is because the water is changing from the gas phase, or water vapor in the air, into the liquid phase.
Why evaporation is called endothermic process?
As a liquid approaches its boiling point, the particles absorb more heat energy making them vibrate faster. … Molecules that are evaporating are absorbing heat. Because the molecules are absorbing heat, evaporation is called endothermic.
Is condensation an exothermic process?
Hence, freezing, condensation, and deposition are all exothermic phase transitions.
Does evaporation occur at the surface of a liquid?
Evaporation takes place only at the surface of a liquid, whereas boiling may occur throughout the liquid. In boiling, the change of state takes place at any point in the liquid where bubbles form. The bubbles then rise and break at the surface of the liquid.
When evaporation will happen from the surface of the liquid?
In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.
Does evaporation of a liquid occur only at a fixed temperature?
No, the evaporation of a liquid occurs at all temperatures.
What are the main forms of condensation and precipitation?
After condensation the water vapour or the moisture in the atmosphere takes one of the following forms — dew, frost, fog and clouds. Condensation takes place when the dew point is lower than the freezing point as well as higher than the freezing point.
What is condensation and forms of condensation?
Condensation is the change of water vapour into water, i.e. from its gaseous form (water vapour) into liquid water. Generally, when warm air rises, cools down and loses its capacity to hold water vapour, condensation occurs. As a result, excess water vapour present in the air condenses to form cloud droplets.
