If we talk about the weather, we should talk about the sky and the air outside and how they look. We see and feel the weather around us every day. When you ask about the weather, you can get various answers depending on what time it is and which season we are in.
Weather is the state of the air and atmosphere at a particular place and time. Weather can change from place to place, from season to season, from day tonight. Weather is something that we experience and feel every day, so it is very important to understand it at an early age.
Explaining the weather to kids can be a fun and dynamic experience. You can find a variety of content everywhere to explain what weather is for all ages. The weather includes sun, rain, snow, and wind. Weather occurs as the Earth is heated unevenly by the sun. That means these temperature changes that occur winds form, which blows hot or cold air. The wind is also responsible for causing the formation of clouds through precipitation and storms.
There are Four Types of Weather
When the weather is sunny, that means that the sky is full of sun. The sun’s energy affects the air pressure and the temperature. Sun gives us the power to do our activities.
The plants need sunlight to grow. Plants make their food by sunlight, this process is “called photosynthesis”. When the sun is up and shining, most animals and reptiles come out to raise their body temperatures and become active. Sunny days are not always hot. Sometimes, they can be cool depending on which season we are in.
Clouds are a huge mass of water vapour. Clouds make a barrier between the sun and us. When there are clouds in the sky, the sun isn’t able to shine and keep the environment warm. It can be warm on a cloudy day when the clouds trap heat near the surface. Clouds are often connected with rain, when we see the sky full of clouds we think of rain.
The wind is the air that moves from one place where there is high pressure to another place where there is low pressure, which means when air is under pressure, it starts to move.
What is the Meaning of “Under Pressure”?
Imagine you are blowing up a balloon, as you blow the air inside the balloon, the balloon blows but when the pressure increases it can pop.
The wind blows when air is pushed smaller spaces of areas. When the weather is stormy, there is a strong wind and heavy rain.
Rain is water droplets that fall from the cloud. When the water droplets from the clouds became too heavy, they fall to the ground. When it’s raining the streets become wet and we find fresh air around us. When the air temperature gets near freezing or below, the snow falls. All things around you become white. It might be hail, hail is formed when the water freezes. That time you can find ice balls around you.
The Four Seasons
The weather changes from season to season. We have four seasons in the year: Spring, Summer, Winter, and Autumn. Let’s see what is the difference between the four seasons:
Spring is famous for its warm weather. Spring sits between Winter and Summer. Spring is celebrated with festivals in many cultures. In Spring plants, trees, and flowers grow, bud and bloom. Trees start to sprout new leaves. Animals are also affected too, they come out of their winter hibernation and begin their nesting and reproducing activities.
Summer is the hottest of the four seasons, coming after spring and before Autumn. High humidity during the Summer is called a heatwave. There are many things to do in Summer like going to the beach, exercising, and eating ice cream. Most people love to do activities in Summer. The night is shorter in Summer.
Autumn, is also known as Fall. Its temperature transitions between Summer heat and Winter cold. Autumn sits between Summer and Winter. The leaves fall from the trees at that time, so it is also called fall.
Do you know that animals collect their food in Autumn in preparation for the coming Winter???
In Winter day and night are equals.
Winter is the coldest season of the year. Winter is the season, which comes between Autumn and Spring. The word Winter comes from an old Germanic word that means the time of water. The weather is very cold and sometimes it rains and snows. The animals start hibernation. Trees and plants stop growing. Nights are longer in winter.
What’s a Tsunami?
A tsunami is an enormous wave, which is caused by an underwater earthquake and/or a volcanic explosion. Sometimes the waves reach heights of over 100 feet (30.5 meters). Most tsunamis about 80 per cent happen in the Pacific Ocean. Because of such large waves, some people can’t compare tsunamis to tidal waves.
When we hear about Tsunami, we are in a great panic. It is important to know the signs of a Tsunami as it is considered a natural disaster. This is a common mistake due to the large nature of the wave itself, but there are nuanced differences that separate the two from each other.
For example, Tidal waves are occurs by the moon, sun, or planet tides. This occurs the wind moves over the water with typical waves. The major difference is the water flow. As waves of tsunamis flow straight, they became more damaging and worrying.
Do you know that the word tsunami originates from a Japanese word, which means “A great harbour wave?
What are Earthquakes?
Earthquakes are sudden shakes of the ground caused by the crossing of seismic waves through Earth’s rocks. When some form of energy is stored in Earth’s crust, seismic waves are suddenly released. About 50,000 earthquakes occur annually in different countries. The size of the earthquake indicates the damage that will happen.
The Size of Earthquakes
- When the earthquake magnitudes start from 2.5 to 5.4, you often feel it and it only causes little damage.
- When the earthquake magnitudes start from 5.5 to 6.0, it causes slight damage to buildings and other structures.
- When the earthquake magnitudes start from 6.1 to 6.9, it causes a lot of damage in very populated areas.
- When the earthquake magnitudes start from 7.0 to 7.9, it causes serious damage.
How do we Measure Earthquakes?
The instruments, which we are used to calculating earthquakes are known as seismographs.
What are Seismographs’ Jobs?
Seismographs are used to monitor the seismic waves, which travel through the Earth after an earthquake begin.
Do you know how Seismographs calculate information about earthquakes?
Modern seismometers have three elements to determine simultaneous movement. They are settled in a very solid position. Each direction of movement gives accurate information about the earthquake.
The Three Directions are:
The instrument is made up of:
1- A-weighted pin.
When earthquakes begin, these tools can record the vibrations from the earthquake. They make lines from the pen onto paper creating a record of the earthquake. This record is known as a seismogram.
It is considered an effective way of discovering the size of the earthquake. So If the earthquake is small, the pen will make a short, wiggly line. And if it’s a big earthquake, it will be a long wiggly line. From here we know the accuracy magnitude of earthquakes.
Thunder and Lightning
What are Thunder and Lightning?
Thunder is a loud rumbling noise heard, it’s the sound that comes from lighting. Lightning is a discharge of electricity. A single shot of lightning can heat the air around it to 30,000°C. The lightning quickly heated the air.
Intense heating causes the hot air, the hot air quickly expands into cooler air around it, which makes a shock wave so we hear thunder. Lightning does not always create thunder. Lightning is the most effective element of a thunderstorm.
