When a circular flow is created by warm air rising and cool air falling this is called:
convection

As elevation increases, does air temperature increase or decrease?
decrease
500
The difference between weather and climate is:
Weather is day to day and climate is weather patterns over time

Human activity is altering the composition of the Earth’s atmosphere and leading to climate change. What is the primary way this is happening?
burning of fossil fuels
