A tiny solid or liquid particle suspended in air or as a gas. Aerosols can be natural, such as fog or gas from volcanic eruptions, or artificial, such as smoke from burning fossil fuels.

A region within the Arctic Circle, defined by the sun's visibility limits on the winter and summer solstices. The high Arctic, the northernmost third, is dominated by snow cover much of the year.

The weather conditions that typically exist in one area, in general, or over a long period.

Further on in the direction in which a stream is flowing or the path at which stream water will flow in its trek to towards the oceans.

The height or altitude at which something exists.

That part of the globe covered by Europe and Asia.

A fast-flowing, high-altitude air current. On Earth, the major jet streams flow from west to east in the mid-latitude regions of the Northern and Southern Hemispheres.

A flat area of land, high above sea level. It’s sometimes referred to as “tableland.” Several of its edges tend to be steeply sloped (cliffs).

The initial plant that sprouts leaves and roots after emerging from a seed.

It's the sometimes oily residues of incompletely burned materials, from plastics, leaves and wood to coal, oil and other fossil fuels. Soot particles can be quite small — nanometers in diameter. If inhaled, they can end up deep within the lung.
