Weather, Climate and Adaptation of Animals to Climate Weather: The day to day condition or temperature of the atmosphere at a specific place is called a weather.

Weather Report: The periodic report about the weather,generally released by the meteorological department is called a weather report. Oftenly, the Weather report is shown along with the news on television. Elements of weather: The miscellaneous elements of the weather are: temperature, humidity, pressure, rainfall, windspeed, etc. Temperature: Temperature of the earth depends upon the duration of sunshine. During the summer season, the span of the sunshine is longer. Due to this, the temperature is high in summer. The temperature is minimum in the morning and maximum at noon. Humidity: Humidity is the amount of water vapors present in the air. Humidity is measured in percentage (%). During rainy season, humidity is at the highest level. Rainfall: Amount of the rainfall is measured in terms of mm (millimeters). For this, an apparatus used is called rain gauge. Wind-speed: Wind speed is also known as wind flow velocity. Wind speed is generated by air moving from high pressure to low pressure, due to changes in temperature. It affects the condition of the weather.
