Evaporation — process?
Liquid water transforms into vapor due to heat.
Condensation — role?

Precipitation types — examples?
Rain, snow, sleet, hail.
Collection — definition?
Water gathering in lakes, rivers, oceans.
Runoff — function?
Water flows over land toward collection bodies.
Evaporation — driven by?
Sun's energy, surface area, temperature, wind.
Condensation — triggered by?
Cooling air reaching dew point.
Precipitation — depends on?
Atmospheric temperature and conditions.
Infiltration — purpose?
Replenishes groundwater by soaking into soil.
