Sunlit Slope and Rising Air
Sunlight warms the rocky slope, and the air just above it becomes lighter. That rising air forms a column that lifts a paraglider while the glider itself keeps sinking through the air.

In the picture
- Sunlit rocky slope: ground surface warmed by sunlight
- Wavy lines above the slope: warmed air beginning to rise
- Column of long upward arrows: rising air that carries the glider upward
- Paraglider with a short downward arrow: the glider sinks through the rising air even as it climbs
Examples
- A hot air balloon rises because the air inside it is warmer and lighter than the air outside.
- Smoke from a chimney curls upward on a still, cold morning as warm air lifts it.
Key takeaways
- Sunlit ground can warm the air above it, making that air rise.
- A glider can climb in rising air even while it is slowly sinking through that air.
