What are the four steps of 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 the weather cycle?
The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.
What is the importance of water cycle Class 6?
Water cycle is important because of the following reasons: (1) Water cycle makes fresh water available in the form of rain: The sea-water is highly salty which is not fit for drinking by animals or for the growth of plants. But the rain water is pure water. It can be utilised by animals as well as plants.
What are the sources of water class 6?
The three main sources of water are:
- Rainwater.
- Groundwater – This includes water bodies like Wells and Springs.
- Surface water – This includes different water bodies like Sea, Oceans, Reservoirs, Rivers, Streams, Ponds, Lakes and Tanks.
What is water cycle in short for Class 6?
Answer: The constant flow of water from the Earth to the atmosphere and back to the Earth is known as the water cycle. The two main steps involved in water cycle are evaporation and condensation. Evaporation is the process in which water changes into vapour due to the heat of the Sun.
What is reflection of light for Class 6?
When light falls on a shiny surface, the light rays bounce back. This phenomenon is called reflection of light. Mirror is a surface from which most of the incident light gets reflected.
What is a shadow for Class 6?
A shadow is a space where light from a light source is blocked by an opaque object. A shadow is formed when a part of light is blocked by the object.
What are the two types of reflection give examples?
There are two types of reflection of light, regular reflection and irregular reflection. Light reflected from mirror is an example of a reflection of light.
What is an example of sound reflection?
It is the sound heard when reflections occur from a firm surface, for example, a wall or cliff. Echo is the repetition of sound even after the source has stopped vibrating. This is used by bats as well as dolphins for the detection of obstacles or navigation.
What are daily reflection examples?
Applications of Reflection of Light in Daily Life
- Meters like ammeters and voltmeters use a mirror to avoid parallax error.
- The wing and rear-view mirrors of a car are made of a convex and a plane mirror respectively.
- A microscope uses a mirror to reflect light to the specimen under the microscope.
What is example of reflecting?
For example, they might have hunched their shoulders as they said, ‘I was so scared; I didn’t know what to do. ‘ We might reflect that back by hunching our own shoulders, mirroring their body language while also saying ‘I felt so scared; I didn’t know what to do.
