Only planets that have an active iron core. Only planets with a magnetic field
It isn't necessarily affected by seasons, because it is caused by unpredictable solar winds... but in the north, they are more likely in the summer, because the northern hemisphere is tilted towards the sun, but can occur year round.
The northern lights don't happen on a fixed schedule; we generally can't predict when they are likely to occur. However, the great-circle route from Denver to London does cross some pretty high latitudes, so there's a good chance that they will be visible.

What is the reason that life is less likely on the outermost planets compared to the innermost planets

Occasionally when solar activity is extremely intense, the Northern Lights may be visible in the state of Washington - the further north and east in the state, the more likely. Solar energy peaks about every 11 years so that's about how often there is a chance of seeing the Northern lights in Washington - but its still rare; it has to be a more energetic peak solar year than normal for the northern lights to stray that far south.

The likely word is the Latin term borealis (northern), used for the Northern Lights (Aurora Borealis).
in the Northern part of Canada where they are the most prevalent since they reflect from the North pole
Aurora Borealis for the northern lights and aurora australis for the southern lights. They can be red, blue, green, even violet. They occur in the winter. ADDED: Actually they occur at any time of year. They are not seasonal, but are much more likely to be visible in Winter simply because the skies are darker and for longer each day. I have been lucky enough to see them, while on holiday in Norway, and that in late August.
At at least 500 feet, but most likely a lot further back.
As the northern lights are a commonly occurring phenomena, it's likely the very first Inuit people were the discoverers of the Northern Lights. This could have been anywhere around the 8th-11th century. It got a lot of attention in the late 18th century when Benjamin Franklin hypothesised as to what caused them
Well the arctic lowlands are very cold and have northern lights in it so the most likely thing to attract people to the arctic lowlands are the northern lights,and maybe to exepernce ski-dooing!

Depending on your location and time, it would vary. From Northern latitudes it's more than likely Saturn and Jupiter. First is Pluto then Neptune
