What is the main reason so many landslides occur during and shortly after periods of heavy rainfall? groundwater saturation causes slopes to be oversteepened water saturation can cause small earthquakes which trigger landslides water in a slope increases driving forces, and saturation causes buoyancy that reduces resisting forces the additional water increases resisting forces O plants have decreased evapotranspiration after rainfall

What is the main reason so many
landslides occur during and shortly after
periods of heavy rainfall?
O groundwater saturation causes slopes to be
oversteepened
water saturation can cause small
earthquakes which trigger landslides
LTE O
water in a slope increases driving forces,
and saturation causes buoyancy that
reduces resisting forces
the additional water increases resisting
forces
plants have decreased evapotranspiration
after rainfall
