Yes, such seeds rely on wind for dispersal. If there were no wind, the seeds would fall near the parent plant, leading to overcrowding. This would limit space and nutrients for growth. Wind helps spread seeds farther to grow in ...
At high altitudes, oxygen is less due to low air pressure. Making pauses allows the body to gradually adjust and produce more red blood cells. Without acclimatisation, one may feel sick. That’s why climbers and soldiers take rest stops to ...
Measuring atmospheric pressure helps predict weather changes like storms or cyclones. Meteorologists, pilots, sailors, mountaineers and disaster management teams use this data to plan safely. A drop in pressure often indicates rain or storms, making such measurements critical for safety ...
At high altitudes, atmospheric pressure is lower, so there is less oxygen in the air. Our bodies struggle to absorb enough oxygen, making us feel dizzy, breathless or tired. This is why people need to rest and adjust gradually at ...
