*********************************
Weather
Weather is the condition of the Earth's atmosphere at a particular time and place.
It includes temperature, rainfall, wind, humidity, and air pressure.
Atmosphere:
It is the layer of gases that surround some planets — in the case of our Earth, we call these gases ‘air’.
The Earth’s atmosphere may be compared to a cake with several layers.
The layer closest to the surface of the Earth is called the ‘troposphere’.
We use many words to describe the weather — hot, cold, rainy, cloudy, humid, snowy, windy, and so on.
Elements of Weather
Temperature: How hot or cold the atmosphere is.
Precipitation: Any form of water, such as rain, snow,
sleet or hail, that falls from the sky.
Atmospheric Pressure: The weight of the air above us,
felt on the Earth’s surface.
Wind: The movement of air, including its speed and
direction.
Humidity: The amount of water vapour in the air.
