Which statement best describes how the Sun’s energy causes the movement of air in the atmosphere?
The Sun warms the air at the surface of the Earth equally, causing the warmer molecules to rise as the cooler molecules sink.

As altitude increases in the atmosphere, the range of temperatures found in each layer does not rise or fall consistently. Which statement best explains why this happens?
The layers of the atmosphere are all at different altitudes – this causes layers further from Earth’s surface to be warmer than layers closer.
The layers of the atmosphere are all different densities – this causes some layers to have a higher temperature although they are at a higher altitude.

Why is it important for scientists to share not only their results, but also their procedure with other scientists? (6.N.1.4)
Scientists don’t care about results, they only want to know the procedure.
So scientists can repeat the experiment and compare methods used, results obtained, and offer further explanations.
