The Sun drives the entire water cycle and is responsible for its two major components: Condensation and Evaporation. When the sun heats the surface of water, it evaporates and ends up in the atmosphere as water vapor. It cools and rises, becoming clouds, which eventually condense into water droplets.
Which of the following drives the water cycle?
The sun , which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds. Cloud particles grow and fall out of the sky as precipitation.
Which of these processes in the water cycle is helped by gravity?
Gravity causes precipitation to fall from clouds and water to flow downward on the land through watersheds . Energy from the sun and the force of gravity drive the continual cycling of water among these reservoirs. As the water is heated, it changes state from a liquid to a gas. This process is called evaporation.
Which of the following are the two major parts of the water cycle?
Evaporation, condensation , and precipitation are important parts of the water cycle.
What is water cycle for Class 3?
The water cycle is the path that all water follows as it moves around our planet . On Earth, you can find water in all three states of matter: solid, liquid and gas. Liquid water is found in Earth’s oceans, rivers, lakes, streams—and even in the soil and underground.
What are the 4 main processes of the water cycle?
So how can we understand this magical process called the water cycle? There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection .
What is runoff in the water cycle?
Overview. Runoff is nothing more than water “running off” the land surface . Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
How do you do the water cycle?
What are the 5 steps of the water cycle?
Student Features. Many processes work together to keep Earth’s water moving in a cycle. There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration . These occur simultaneously and, except for precipitation, continuously.
What is the driving force of the water cycle quizlet?
The SUN is the driving force behind this stage of the water cycle. The SUN heats up the water, allowing some molecules to gain enough energy to undergo a phase change from a liquid to a gas. The SUN is the driving force behind this stage of the water cycle.
Which of the five water cycle processes are directly caused by the force of gravity?
Which parts of the water cycle are caused by the force of gravity? precipitation, runoff, infiltration, grand water flow .
What is water cycle for Class 9?
The process in which water evaporates and falls on the land as rain and later flows back into the sea via rivers is called water cycle. 1)Water evaporates from hydrosphere(oceans, seas, river, lakes, ponds)with sun’s heat and form clouds.
What is water cycle for Class 6?
What is the water cycle? The constant movement of water from the earth to the atmosphere as water vapor, and back to earth as rain is known as the water cycle or hydrological cycle. The sun and the water bodies such as the oceans, seas, rivers and lakes are the components of the water cycle.
What is water cycle for Class 8?
What is Water Cycle? The water cycle, also known as the hydrologic cycle, is the continuous movement of water from the earth’s surface to the atmosphere and then back to the ground . It is a continuous process. Hence, it does not have a starting or an ending point.
What are the 7 steps in the water cycle?
- Step 1: Evaporation. The water cycle begins with evaporation. ...
- Step 2: Condensation. As water vaporizes into water vapor, it rises up in the atmosphere. ...
- Step 3: Sublimation. ...
- Step 4: Precipitation. ...
- Step 5: Transpiration. ...
- Step 6: Runoff. ...
- Step 7: Infiltration.
What causes runoff water?
Runoff picks up fertilizer, oil, pesticides, dirt, bacteria and other pollutants as it makes its way through storm drains and ditches – untreated – to our streams, rivers, lakes and the ocean. Polluted runoff is one of the greatest threats to clean water in the U.S.
What are the factors that affect runoff?
Temperature, wind speed, and humidity are the major meteorological factors, which affect runoff. Temperature, wind speed and humidity affect evaporation and transpiration rates, thus soil moisture regime and infiltration rate, and finally runoff volume.
How does infiltration control runoff?
When water is added to the soil slowly in precipitation or irrigation, all the water can infiltrate the soil. When the irrigation rate is excessive, or the precipitation comes rapidly, the infiltration rate is exceeded, resulting in runoff .
What affects the water cycle ks2?
The water cycle is powered by the sun . The heat from the sun increases the temperature of our rivers, lakes, and oceans. This causes surface water molecules to transform into vapour. This first stage of the water cycle is called evaporation.
Why is the water cycle?
The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet . If water didn’t naturally recycle itself, we would run out of clean water, which is essential to life.
