Topic 3: Why does the air temperature get warmer and colder?

Please note: the questions listed are not the only items that you need to know. The questions point out basic information to help understand some topics, some concepts that may not be obvious to all students, and some of the more difficult concepts.

Energy in, energy out, and temperature

Radiation  

  • What emits radiation? What happens to radiation?

Why is it warmer in the summer and colder in the winter?

  • What determines how much solar radiation we get during a day?

  • How does the path of the sun in the sky affect the solar radiation we receive?

  • How does the path of the sun change during the year?

  • How does the changing path make our temperatures warmer in the summer and colder in the winter?

  • Animation of sun's path in sky

  • Coldest place in the world video

Why is it warmer in the daytime and cooler at night?

How do clouds affect day and night temperatures?
