Name: _____________________________________ ES 1 2 3 4 Physical and Chemical Weathering Notes Date: ________________ What is weathering? • Weathering is the process that produces change in the surface of rocks exposed to the atmosphere and/or hydrosphere. • The end result of weathering produces sediment. What is Physical (or Mechanical) Weathering? • Breaking rock by force into smaller pieces • There is NO change in the rock’s composition • Total exposed surface area increases Examples of Physical Weathering: Type Caused by… Examples include… Name: _____________________________________ ES 1 2 3 4 Physical and Chemical Weathering Notes Date: ________________ What is chemical weathering? • Unlike physical weathering because rock composition is changed after reacting with a chemical • Like physical weathering because it breaks down rock Examples of Chemical Weathering: Type Caused by… Examples include… Name: _____________________________________ ES 1 2 3 4 Physical and Chemical Weathering Notes Date: ________________ Directions: Using the diagram of the types of weathering dominating particular climates, answer the following questions. 1. a) If an area has a mean annual temperature of 0oC and a mean annual precipitation of 50 cm, what type of weathering would be dominant? b) According to the climate, where would you find this area on Earth? Why? 2. a) If an area has a mean annual temperature of 60oF (use your ESRT to convert to oC) and a mean annual precipitation of 150 cm, what type of weathering would be dominant? 60oF = ____oC b) According to the climate, where would you find this area on Earth? Why? Name: _____________________________________ ES 1 2 3 4 Physical and Chemical Weathering Notes Date: ________________ 3. a) Would our area be dominated by any form of frost action? Why, or why not? (HINT: NY has a mean annual temperature of about 18oC and annual precipitation of 115 cm) b) What other physical weathering processes would you expect to be common in our area? **Challenge Questions** 4. a) Is Long Island a likely place to have caves? Why? (HINT: Use pg 3 of your ESRT to identify which types of rocks are found where) d) Where in NY State would you find caves? Explain.
