WEATHER Bell #1 Answer:

(1) Weather is the state of the atmosphere at a given time and place. (Yes! This IS from a textbook!)

(2) Because I live on the surface!

(3) How the sun heats different parts of our planet in different ways so some part are hot and some parts are cold.



(1) Nitrogen

(2) Oxygen

(3) Nitrogen is used by living organisms to produce things like protein. Nitrogen plays an important role for life.

(4) Oxygen is essential for all living animal organisms on the planet. We need it to breathe!


(1) & (2) Thermosphere - where weather occurs Stratosphere - where Ozone is present Mesosphere - where meteorites burn up Thermosphere - where unmanned spacecraft orbit the Earth

(3) I live in the Troposphere.



(1) Hot air rises because is is less dense than the air around it.

(2) Cold air sinks because it is more dense than the air around it.

(3) The Convection Currents in our atmosphere circulate the heat from the sun around the planet Earth.



(1) Weather is the state of the atmosphere at a given time and place. If it’s raining, I have to grab an umbrella. If it’s really hot outside, I wear shorts and sandals.

(2) Look out the window! Check the forecast on the radio or TV.

(3) Meteorologists observe temperature, air pressure, precipitation, wind speed and direction, etc.



(1) Radiation, Conduction, and Convection.

(2) Radiation if your room is heated by radiators and it’s cold outside. Convection above your head as your body heat heats the air above you. ETC.

(3) This answer will change from school to school, state to state, season to season!



(1) Air Pressure - Barometer; Wind Speed and Direction - Anemometer

(2) This answer will change from school to school, classroom to classroom!

(3) Weather Satellite.



(1) Cold Fronts bring heavy rain in violent thunderstorms.

(2) Warm Fronts bring slow, steady rain.

(3) The are both attached to a Low Pressure System.


(1) Ozone is a form of oxygen with 3 Oxygen atoms.

(2) Ozone can hurt us because in the Troposphere it can cause damage to our lungs.

(3) Ozone can help us because in the Stratosphere it protects us from ultraviolet radiation from the Sun.

(1) Troposphere, Stratosphere, Mesosphere, and Thermosphere.

(2) Nitrogen and Oxygen.

(3) Radiation, Convection, and Conduction.



(1) Weather is the state of the atmosphere at a given time and place.

(2) A Meteorologist studies the weather and predicts the future weather of an area.

(3) Rising pressure brings the possibility of sunny weather.



(1) Weather in the United States comes mainly from the west.

(2) Dropping pressure brings the possibility of rainy weather.

(3) Rising pressure brings the possibility of sunny weather.



(1) A good answer would be the Troposphere because that’s where you live. There are other good answers, too!

(2) A good answer would be Temperature and Precipitation. There are other good answers, too!

(3) A good answer would be Low and High Pressure Systems and Weather Fronts. There are other good answers, too!
