Concept:Weather and climate are described using measurable elements, while controls are factors that influence those elements.
Explanation:Elements of weather and climate include temperature, rainfall, humidity, pressure, and wind.
Controls of weather and climate include latitude, altitude, air masses, ocean currents, and distance from the sea.
