What is water cycle for Class 4?
There are four main stages in the water cycle.
They are evaporation, condensation, precipitation and collection.
Let’s look at each of these stages.
Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas)..
Does rain clean the air?
As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates, and organic particles.
What is water cycle with diagram?
It is also known as the hydrological cycle or the hydrologic cycle. During the process of the water cycle between the earth and the atmosphere, water changes into three states of matter – solid, liquid and gas. The diagram of the water cycle is useful for both Class 9 and 10.
Which process causes rain?
Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. … Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.
What is stratiform rain?
Stratiform precipitation may therefore be defined. as a process in which the vertical air motion is generally small compared to fall velocity. of ice crystals and snow. More specifically, precipitation is defined to be stratiform if the. mean vertical velocity of the air w averaged over an atmospheric volume containing.
Why does it rain simple answer?
Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air. This vapour rises, cools, and changes into tiny water droplets, which form clouds. … When the water droplets get too large and heavy, they fall as rain.
How do you introduce the water cycle to students?
To introduce the water cycle to my primary science students, I always start out with an interactive read-aloud using the story Little Cloud….A Simple Book to Teach the Water Cyclewaving fingers go up above our heads for evaporation.clasp hands together for condensation.and waving fingers go down for precipitation.
What are the 4 types of rain?
Types of PrecipitationRain. Most commonly observed, drops larger than drizzle (0.02 inch / 0.5 mm or more) are considered rain. … Drizzle. Fairly uniform precipitation composed exclusively of fine drops very close together. … Ice Pellets (Sleet) … Hail. … Small Hail (Snow Pellets) … Snow. … Snow Grains. … Ice Crystals.
What is water cycle in simple words?
The Short Answer: The water cycle is the path that all water follows as it moves around Earth in different states. Liquid water is found in oceans, rivers, lakes—and even underground. Solid ice is found in glaciers, snow, and at the North and South Poles. Water vapor—a gas—is found in Earth’s atmosphere.
What is the rain cycle called?
The water cycle is called the hydrologic cycle. In the hydrologic cycle, water from oceans, lakes, swamps, rivers, plants, and even you, can turn into water vapor. Water vapor condenses into millions of tiny droplets that form clouds. Clouds lose their water as rain or snow, which is called precipitation.
What is rain for kids?
forms. It may be a liquid, a solid called ice, or a gas called water vapor or steam. Rain is the liquid form of water that falls from the sky in drops. … It provides the fresh water needed by humans, animals, and plants. If too much rain falls, however, dangerous flooding may happen.
What is the smell of rain called?
PetrichorPetrichor (/ˈpɛtrɪkɔːr/) is the earthy scent produced when rain falls on dry soil. The word is constructed from Greek petra (πέτρα), “rock”, or petros (πέτρος), “stone”, and īchōr (ἰχώρ), the fluid that flows in the veins of the gods in Greek mythology.
What is a relief rainfall?
Relief or orographic rain is formed when air is forced to cool when it rises over relief features in the landscape such as hills or mountains. As it rises it cools, condenses and forms rain. The highest rainfall totals of over 1,600 mm per year occur in the mountain areas along the west coast.
Is rain water clean?
Most rain is perfectly safe to drink and may be even cleaner than the public water supply. Rainwater is only as clean as its container. Only rain that has fallen directly from the sky should be collected for drinking. … Boiling and filtering rainwater will make it even safer to drink.
What is Ncert 7th water cycle?
Basically, the water cycle is a process, in which water evaporates from the surface into the atmosphere, cools and condenses through the rain in clouds and again fall on the surface with the process of precipitation. …
