Mechanical(Physical) Weathering Chemical Weathering Definition: Definition: Illustration: Illustration: List the agents (causes) of Mechanical (Physical) Weathering Ice List the agents (causes) of Chemical Weathering water Wind Water Gravity Plants and Animals Ice Wedging (Definition)- acids in groundwater acid precipitation acids in living things (plants and animals) air (oxidation) Explain how water can cause rock to chemically weather. Illustration: Abrasion (Definition)- What are the 3 main types of precipitation? Define acid precipitation- Illustration: What is the main cause of acid precipitation? Name 3 agents that can cause abrasion and explain how each agent causes rocks to weather mechanically. Water- Wind- Gravity- Explain how acids in living things cause rocks to chemically weather. (Biological weathering) Explain how plants can cause mechanical weathering. (Biological weathering) Describe how caves or caverns underground are formed. (Acids in groundwater) Describe how animals cause mechanical weathering? (Biological weathering) When oxygen in the air reacts with metal, oxidation occurs and causes the metal to______________. In addition, name some animals that can cause this type of weathering. What is iron oxide? What agent of weathering can weather rock mechanically and chemically? _______________ Draw a Venn diagram comparing and contrasting mechanical and chemical weathering.
