Atmósfera - Atmosphere - the layer of gases that surrounds the Earth . - Atmospheric phenomenon - a natural event that occurs in the troposphere . - Autumn - the season of the year when days and nights are almost the same length , and the weather gradually gets colder . - Cloud - a visible accumulation of tiny water droplets in the ski . - Hail - a solid ball - shaped form of precipitation . - Lightning - the bright flashes of light that occur during storms . - Outer layers - the layers of the atmosphere furthest from the Earth . - Rain gauge - an instrument for measuring the amount of rain that falls in one day . - Spring - the season of the year when days and nights are almost the same length , and the weather gradually gets warmer . - Storm - an extreme atmospheric phenomenon with strong winds and heavy rain . - Stratosphere the middle layer of the atmosphere that contains the ozone layer - summer the season of the year when days are longer than nights and the weather is hot . - Thermometer - an instrument for measuring temperature . - Troposphere - the layer of the atmosphere closest to the Earth that contains oxygen . - Water vapour - water in a gaseous state . - Weather - the state of the atmosphere at a specific time and place . - Weather station - a place where instruments are located that measure the weather . - Weather vane - an instrument that shows the direction of the wind - Wind - moving air - Winter - the season of the year when nights are longer than days and the weather is cold . 2 Cloud gauge Rain Autumn Weather Storm Wind phenomenon Weather Lightning Stratosphere station Atmosphere pollution Winter summer Outer Thermometer Spring Troposphere Weather Atmospheric Anemometer vapour Hail Water vane layers Air - the contamination caused by harmful gases released into the atmosphere - - an instrument for measuring wind speed . - the layer of gases that surrounds the Earth . - a natural event that occurs in the troposphere . - the season of the year when days and nights are almost the same length , and the weather gradually gets colder . - a visible accumulation of tiny water droplets in the ski . - a solid ball - shaped form of precipitation . - the bright flashes of light that occur during storms . - the layers of the atmosphere furthest from the Earth . - an instrument for measuring the amount of rain that falls in one day . - the season of the year when days and nights are almost the same length , and the weather gradually gets warmer . - an extreme atmospheric phenomenon with strong winds and heavy rain . the middle layer of the atmosphere that contains the ozone layer the season of the year when days are longer than nights and the weather is hot . - an instrument for measuring temperature . - the layer of the atmosphere closest to the Earth that contains oxygen . - water in a gaseous state . - the state of the atmosphere at a specific time and place . - a place where instruments are located that measure the weather . - an instrument that shows the direction of the wind - moving air - the season of the year when nights are longer than days and the weather is cold .
