Physical weathering

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

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…

This boulder displays characteristics of frost shattering/freeze thaw weathering as shown by the horizontal and vertical cracks along the rock's lines of weakness caused by low temperatures and water penetration.

Weathering is breaking down rocks, soil, and minerals as well as wood and artificial materials by contacting the atmosphere, water, and biological organisms

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

On a recent vacation to the Bahamas , Paradise Island in particular, while the rest of my crew was swimming, reading and kicking ...

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Biological Weathering is a natural phenomenon that occurs on rocks due to living organisms such as plants, animals, & micro-organisms (fungi/algae). Explore different types of biological weathering here.
