Introduction:

Introduction We all ways heard & see different type of weather, but use know what is a weather. In this power point presentation I will tell you about you about some question than their answer & some small question answer related to them. There will some amazing facts also.

What is weather?:

What is weather? Weather is the name given to the changing condition of the atmosphere, or air, which surrounds the Earth . Weather condition include wind, storms, rain, snow and sunshine. Q. What is climate? A. The average weather condition over a long period time. Q. What is atmosphere? The mixture of gases which nitrogen, oxygen, water vapour and tiny amount of other gases. They protect us from the scorching rays of the Sun from the icy chill of the night.

Q. Why do we have day and night? A. During every 24 hours, the Earth spins around on its axis turning us towards the light of the light of the Sin and away again , thus giving us night and day. Q. Why do we have seasons? A. The four seasons - spring, summer, autumn winter are caused by the tilt of the Earth’s axis, different parts are titled towards the Sun for a few months at a time. The part leaning towards the Sun has summer, while the part leaning away has winter

Facts time…:

Facts time… Planet mars also spins with a tilted axis so it has seasons very similar to Earth. People who study the weather are called meteorologists. People who study climate are called climatologists.

What is air pressure?:

What is air pressure? Although we cannot see it, air has weight which causes it to press down on the Earth and everything on it. Changes in the air pressure affect the weather. Q. Why is air pressure important to weather forecasters? Air pressure changes constantly, bringing different types of weather . These changes help weather forecasters to predict rainy weather, which usually comes with high pressure.

PowerPoint Presentation:

Q. Can we feel air pressure? A. No, usually. However, occasionally when you go up or down a hill in a car, your ears may feel funny due to the change of air pressure. The same thing can happen in an aircraft. Q. What is the normal pressure on low ground, near sea level? Normal pressure at this low level is about 1,000 millbars.

Facts Time…:

Facts Time… Highest pressure recorded was 1084 millbars in Siberia. The lowest was 870 millbars in a typhoon over the Pacific Ocean. The cabins of aircraft are specially pressurised so that the crew and passengers do not suffer from less and less air pressure the higher the plane flies.

What is wind?:

What is wind? Wind is air moving from one place to another as it warms up or cools down. Q. What is the Beaufort Scale? A. This is a method of estimating the wind speed if you don’t have an anemometer. Q. What is the difference between a gust of wind and a lull? A gust is an abrupt rush of wind. A lull is when the wind gets lighter for a few seconds

Facts time……!:

Facts time……! The world’s windiest place is Commonwealth Bay, Antarctica. A weather vane shows the wind direction.

What are clouds?:

What are clouds? Clouds are made up of billions of tiny drops of water . They form in different shapes and at different heights in the sky. Q. How does a cloud form? A. A cloud is forms when moist air rises upwards. As the air cools, it expands and changes, or condenses, into tiny water droplets. The highest clouds contain ice crystals

PowerPoint Presentation:

Q. Can a aircraft fly through clouds? A. Yes, very easily. The water drops, or ice crystals, are so tiny that they barely affect an aircraft’s progress.

Facts time:

Facts time When air is forced upwards over a barrier such as hill or mountains, clouds form. … !!!

Why do we needs rain???:

Why do we needs rain??? Rain provides the water that is necessary for the survival of plants, animals and humans. Without rain almost the only life on Earth would only in the oceans.

PowerPoint Presentation:

Q. What makes it rain? A. As the Sun heats up Earth’s oceans and rivers, water turns into an invisible gas called water vapour. As the vapour rises it rises up it turns into water droplets. When they grew very heavy they fall. In this way, the same water evaporates and turns into rain again and again. This is know as the water cycle.

Facts time…!!!!!:

Facts time…!!!!! The driest place in the world is the Atacama desert in Chile , where the rainfall is less than 0.1 millimeter per year.

When does it snow?:

When does it snow? The snowfalls tend to occur when the temperature is around freezing point. Q. When does the coldest weather occur? In most countries the coldest times are clear, calm nights when there are no clouds to keep the heat near the Earth’s surface.

PowerPoint Presentation:

Q. Can snow be useful? A. Yes, It can help crop – such as winter wheat – by protection them from very hard frosts and cold dry winds . Also, it can be fun for skiing, sledging and for making snowballs and snowman.

Facts time…………:

Facts time………… Some animals, such as Polar bears, are speciall abapted to live in a snowy climate
