Use the drawing tool to modify the model, showing the direction of prevailing winds in the Northern hemisphere and convection currents. Label hot and cold air on your convection currents.

The brightest star in the night sky in the northern hemisphere is sirius. its distance from earth is estimated to be 8.7 light years. a light year is the distance light travels in one year. light travels at a speed of 3.00 × 108 m/s. calculate the distance from earth to sirius in miles.
