1 Compare Igneous RockSedimentary Rock

2 Clastic Sedimentary Rock

4 Sedimentary Rock How do those layers form? Order or process: WeatheringErosionDeposition Cementation & Compaction

5 Mechanical Weathering Disintegration/rock broken into smaller pieces Disintegration – Frost Action Frost Action – Abrasion (river, glacial, sandy environment) Abrasion – Plants and Animals #2 Plants and Animals #2

6 Chemical Weathering Decomposition-rock’s minerals are changed into different substances. – Acid Rain – Oxidation Oxidation – Hydrolysis Hydrolysis – Caves Caves

7 Which minerals are susceptible? Chemical Weathering – Calcite Mechanical Weathering – Quartz, angular minerals

8 Chemical Weathering What affects the rate? Faster Chemical Weathering – Warm and Moist climate Faster Physical Weathering – Cold and Wet Climate

15 Erosion The transport of sediments/particles from a weathered rock by – Water – Wind – Glacier – Gravity

16 Water Distinguishing Characteristics: – rounded edges

17 Wind Distinguishing Characteristics – Flatten sand surfaces: Sand dune

18

19 Glaciers Distinguishing Characteristics – Striations-special scratch by minerals Striations

20 Effects of Erosion Landslide Mudslide

21 Evidence of stream Erosion

22 Evidence of Glacial Erosion U Shape Valley

26 Sorted vs. Unsorted

27

28 Factors of Deposition Size Density Shape

29 Two types of deposition Water - sortedsorted Glacier - unsorted

30 Alpine Glacier Slow moving stream of ice that flows within valley walls

31 Juneau Icefield in Alaska

32 Arrete cirque Horn

33

34

35 Continental Glacier Glacier that covers a large part of a continent Ex: Greenland, Antarctica

36

37 Glacial Depositional Features

38

39 Moraine and Till Till - Unconsolidated and unsorted rock material that is deposited by a retreating or melting glacier Moraine – The accumulation of glacial till

40 Drumlin Elongated whale-shaped hill formed by past glacial action as it moves over the till

41 Drumlins in NYS South ends of the Finger Lakes - northeast of Ithaca at the northern end of Cayuga (Rochester to Syracuse)

42

43 Erratics A large boulder that have been transported into an area by a glacier

44 Kettles and Kame Hollows left behind by melting ice as the last remnants of glaciers disappear

45 Kame Small coned shaped hill of sand and pebble. that are deposited by stream into the kettle

46 Complete Illustration When glacier melts, deposits slump down at the side and form long ridges - ESKER
