Mechanical vs. Chemical Weathering

Mechanical vs Chemical Weathering: What's the difference? Learn how rocks break down!

What is the definition of chemical and mechanical (physcial) weathering? 1. Physical Weathering - the process by which rock is broken down into smaller pieces. The rock's composition does NOT change by this process.2. Chemical Weathering - the breakdown of rock material. This breakdown causes the rock's composition to change. Sort the agents of weathering into physical or chemical. You WILL have an equal number in each category. 🚨HINT (Lichen and Moss are plants that release acid) 🚨 There will be six in each category. Physical Abrasion Plant Root Growth Wind Ice Wedging Moving Water Animal Actions Chemical Acid Precipitation Acids in Groundwater Acids in Living Things Rust Carbonation (C02) Moss How is plant root growth (root wedging) and ice wedging similar? Both happen only in warm temperatures. Both happen only in cold temperatures. Both happen quickly. Both occur slowly over time. How is physical and chemical weathering similar? Both change the composition of the rock material. Both break down rocks. Both do not change the composition of the rock. Choose if the image is chemical or physical weathering.
