Question

which correctly lists three factors that are important to consider when forecasting weather?
clouds, isotherm, butterfly effect
isotherm, air pressure, temperature
air pressure, temperature, clouds
temperature, clouds, isotherm

Explanation:

When forecasting weather, air pressure, temperature, and clouds are directly observable and relevant meteorological elements. Isotherms are lines on a map connecting points of equal temperature (a representation, not a factor in the sense of a measurable entity like air pressure, temperature, or clouds). The butterfly effect is a concept in chaos theory (not a direct factor in routine weather - forecasting data collection).

Answer:

air pressure, temperature, clouds
