oxygen and water react with iron to cause rusting on a rock

• physical weathering

• deposition

• chemical weathering

Which of these is an example of chemical weathering?

• Water seeps into cracks in rocks, freezes, and expands

•  

  Wind slowly scrapes away small particles of rock

• Acid reacts with certain types of rocks causing the rocks to break down

• Plant roots grow into gaps in rocks and force the gaps wider

What is Abrasion?

• When rock is broken into smaller pieces by the scraping of other materials

• Oxygen and water change the composition of the minerals in a rock

• Water getting into cracks, freezing, and expanding

• Mosses growing on a rock and producing acids that wear away the rock

What are sediments? 

• acid rain dissolving rock

• dropping or laying down eroded materials in a new location

• wind, water, ice, and gravity

• fragments of weathered rock
