Present day

Erosion experiments… Experiment 1: Shaking rocks in a bottle In this experiment we… This showed what happened when rocks travel with a stream. Experiment 2: Acid on limestone In this experiment we… This showed the damage that can be caused by acid rain. Experiment 3: Heating and cooling a rock In this experiment we… This showed the damage that can be done when a rock is heated and cooled, like during the day and night. Describe what you did here…

Rock fragments When rocks are transported by a river they are eroded: When rocks are broken off they can form “scree slopes” Rock shape up here Rock shape down here “Sediment”

Weathering by ice “Onion skin” weathering

Erosion and weathering… EROSION is when rocks are gradually worn down. WEATHERING is when rocks are broken up into smaller ones. The ultimate result of both of these processes is SOIL.

Examples of erosion… ErosionPhysical, chemical or biological? Rocks bumping into each other while travelling down a stream Tree roots pushing against the rock Ice getting into cracks and expanding Acid rain Animals or plants digging into cracks “Onion skin weathering”
