How does weathering change earth's surface?

DIRECTIONS: Match the names of physical weathering agents with a brief explanation. Temperature Changes These changes cause rock to expand and contract, resulting in cracks or crumbling rocks over time. Animal Action Burrowing organisms causes more rock to be exposed, increasing the weathering process. Plant Action Increasing pressure from root growth can cause rock to break apart. Wind Abrasion from small particles carried in the air can blast away at surfaces causing them to slowly wear away. Water Abrasion from tumbling rocks hitting against each other causes rock to become rounded and smooth. Gravity Abrasion from falling rocks hitting against other rock causes larger pieces to break apart. Ice Sliding and flowing ice can weather the rocks over which ice moves. This process created sediments that glaciers carry away Ice Wedging Write a caption for each to describe the process of ice wedging.

Acid precipitation is an agent of chemicalweathering.The gradual wearing away or breaking down of rocks by abrasion is a type of physicalweathering.The process of oxidationcauses rocks to change composition when reacting with oxygen.The mechanical breakdown of rocks by the action of other rocks and sand particles is called abrasion. What are some similarities and differences between physical and chemical weathering? Physical Weathering Both Chemical Weathering no change in rock composition break down rock change in rock composition Physical vs Chemical Weathering Sort each into the proper category. Physical Weathering plant root growth abrasion by gravity wind movements temperature changes moving water Chemical Weathering oxidation acids in groundwater acids in living things
