Water Pollution Today we are going to investigate how much water pollution which comes from School could eventually end up in the local rivers‚ creeks‚ wetland or groundwater. The first thing we need to do is estimate how much water falls on the school‚ and which surfaces it falls on (e.g. roof‚ paths‚ car parks‚ grass). Task 1: Placing the school catchment Using the map of the Manly Council‚ locate School. Pittwater House is in the catchment area of ________________________. The water run-off

The main characteristic of a tropical rain forest biome is the presence of Warm temperatures throughout the year. In a tropical rain forest biome‚ there are three layers. These layers include the top trees‚ followed by the canopy layer characterized by dens leaves hence low light penetration and the third layer are the ground layer. The ground layer lacks any vegetation owing to

it spreads back toward the poles. When it gets to the poles‚ it descends back to the surface again to complete the cycle. The heat of the Sun causes water to evaporate from lakes‚ rivers and oceans‚ as well as from the leaves of plants called (transpiration). But this water doesn ’t just disappear; it ’s absorbed into the atmosphere and carried around the world by currents of air. Eventually the water in the air condenses to form clouds‚ which return it to Earth as rain or snow. The water that collects
