Chunky Weathering and Erosion Earth’s surface breaks into chunks and the chunks move. The breakdown of rocks at or near Earth’s surface is called? weathering What are the two types of weathering? Physical and chemical Which type of weathering actually changes a rock’s composition? chemical What is it called when ice expands in a crack in a rock? Ice wedging or frost action Abrasion is a form of which type of weathering? physical When limestone bedrock dissolves due to chemical weathering it can form? Sinkholes or caverns An example of biological weathering would be . . . Plant root in rock The weathering of bedrock ultimately forms this important material. soil The driving force of most erosion is? gravity Which of the following are considered mass movement? soil creep landslide rock fall They’re all mass movement V-shaped valleys are carved by? Rivers and streams True or false – rivers produce sharp edged sediments False – they produce rounded sediments Draw the cross section from x to y At what letters will erosion take place? B&D The area of land drained by a stream is called a? watershed What type of erosion created this formation? wind Glaciers carve what shape valleys? U What arrangement of sediments are left by glaciers? Unsorted What other evidence of glaciation might be found in a U-shaped valley? Striations or erratics This glacial formation is called a? drumlin This long narrow island is formed by? Longshore current or wave action Which erosive force formed these lakes? Glaciers Where on Earth is this process the most dominant type of erosion? Beaches and deserts Which erosive force moved this boulder to its present location? Glaciers A decrease in the velocity of a stream will most likely cause an increase in _______________. Deposition The Mohawk River runs into the Hudson River. Therefore, the Mohawk would be considered part of the Hudson’s ______________. Watershed Landscapes will undergo the most chemical weathering if the climate is _______ and _______. Warm and wet Which of the following sediments will be transported by a glacier? A) Boulders B) cobbles C) pebbles D) sand E) silt F) clay All of them What erosive force formed this valley? A river
