Physical weathering

Ice wedge

frost wedging - a type of disintegration in which jointed rock is forced apart by the expansion of water as it freezes in fractures.

Weathering is the wearing down or breaking of rocks while they are in place. Weathering can be biological, chemical or physical.

Weathering is the breaking down of rock into sediments (like sand, pebblies, silt, and clay) by the weather,either physically or chemically.

Physical weathering occurs naturally over the course of time. Explore these physical weathering examples to uncover how this happens for different reasons.

We have been plugging away with our large landform unit. As we wait for the Foss Kits to show up I have been busy teaching weathering. As we move away from weathering onto erosion I wanted to show what we have done so far. Here is what we have done in science in the past two weeks (not including the GLAD component which I will make a separate post on later): Weathering Experiment: I took some different rocks from my yard (pebbles and decorative rocks bought at Home Depot) and placed them in…

Recent hurricanes and other disasters give insight into the future of a livable planet.

Mechanical or physical weathering are processes that turn big particles of rock into smaller particles over time.

Scientists fear global temperature records will be breached if the phenomenon unleashes its full power in 2024
