Groundwater can stay underground for a few days to thousands of years, depending on factors like the geology of the area, depth of the water table, and rate of extraction. In some cases, groundwater can flow rapidly through porous rock and be replenished quickly, while in others it can be stored for long periods before recharging.
When it rains, the water seeps into the ground and infiltrates into the soil, filling up the spaces between rocks and sediment. This excess water becomes groundwater, which can either stay in the ground or flow through underground aquifers. Ultimately, some of this groundwater may resurface as springs or discharge into rivers, lakes, or oceans.
Groundwater forms when precipitation infiltrates the soil and trickles down through permeable rock layers until it reaches an impermeable layer of rock or clay. The water accumulates in the pore spaces of the rock, creating underground reservoirs called aquifers.
Tornadoes can stay on the ground for anywhere from a few seconds to more than an hour, depending on their size, strength, and the terrain they encounter. The average duration of a tornado on the ground is about 10 minutes.
The average tornado lasts about 10 minutes. However, duration can vary greatly. Some tornadoes last only a few seconds. In rare cases a tornado can be on the ground for an hour of more. The infamous Tri-State tornado of 1925 is believed to have been on the ground for over three and a half hours.
