27. Formation of Sedimentary Rocks

28. Lithification - Clastic

29. Lithification - Chemical

30. Clastic Rocks Mixed sediment sizes.Sorted Sediment sizes. Conglomerate Sandstone Rounded pebbles, sand, clay Made almost exclusively from sand

31. Clastic Rocks Mixed sediment sizes.Sorted Sediment sizes. Breccia Shale Angular pebbles, sand, mud, clay Almost entirely clay

32. Chemical Rocks Chemical RockBiochemical Rock Limestone Coquina Almost entirely Calcite Clastic- chemical rock. Made of shells Will fizz with Acid

33. Classifying Sedimentary

34. Sedimentary Features Strata Fossils Ripple Marks Mud Cracks

35. Coastal Plain

36. A gently seaward sloping surface in Eastern Va West East Thin Thick “__PILE___” of loose sediments that have eroded from the mountains. The highest elevation is about 300 ft. above sea level

37. Coastal Plain Rock Type: – Loose sediment, sedimentary rocks Age: – 0-225mya (Million years ago) Fossils – Oceanic (Sea shells)

38. Valley and Ridge

39. An area of long, parallel ridges separated by valleys Caves and caverns

40. Valley and Ridge Rock Type: – Ridges: Hard rocks – Valleys: Soft rocks (like limestone) Age: – 350-570mya Fossils – Sea (ex. Shells)

41. Appalachian Plateau

42. Coal seam

43. Appalachian Plateau Rock Type: – Sedimentary Age: – 286-360mya Fossils – Tree – Fern – Some Sea
