Through permeable rock strata like sandstone, groundwater usually travels slowly within the ground. Option (3) is correct.
Through the crevices between rocks, water is forced downhill and sideways by gravity and pressure. In order to maintain the water cycle, it eventually reemerges to the land's surface, into rivers, and into the oceans. Gravity causes ground water to go downward from higher recharge locations to lower recharge areas, where it can either be retained in aquifers or released into streams.
Deeper = slower movement = longer residence time in groundwater systems. The majority of groundwater comes from precipitation in the form of rain or snow, which is meteoric water. Water from the surface seeps into the ground as soon as the water touches the earth. Due to interconnected pore spaces, water can travel through rock and soil underground.

4. completely fills the zone of saturation above the water table.
True or False? Landslide-potential maps designate areas in which construction is illegal because of the high risk of mass movement there.
The statement, "Landslide-potential maps designate areas in which construction is illegal because of the high risk of mass movement there." is false.
The potential threat posed by landslides is depicted on many types of maps. These maps might be as straightforward as one that shows where past landslides have occurred to denote possible risk, or they could be as sophisticated as one that incorporates probabilities depending on elements like rainfall, slope angle, soil type, and earthquake shaking intensity.
Maps depicting the likelihood of landslides as well as the projected losses in lives and property, should one occur. Landslide hazard maps show the likelihood of landslides in a certain location. An ideal landslide potential risk map displays both the likelihood that a landslide will develop at a certain location and the likelihood that it will move downslope a specific distance.
