Settlin’ Sediments Sedimentary Rocks
Do Now • One of these rocks is an igneous rock, while the other is a sedimentary rock. • Which one is which? Compare and contrast the two.
Essential Question How are clasticsedimentary rocks different from nonclasticsedimentary rocks?
You will be able to: Classify a sedimentary rock as either clastic or nonclastic. Differentiate between the origins of both types of sedimentary rocks.
Prepare for the Activity • Work in groups of four.
Discussion Notes Clastic sedimentary rocks are composed of sediments that were either cemented or compacted (pressed). Nonclastic sedimentary rocks are the result of evaporation or precipitation in a liquid. • Sedimentary Rocks are the composed of weathered sediments of any size and shape. • They are classified by the way they form and the composition of their sediments.
Discussion Notes (cont.) Other sedimentary rocks are formed from solutions as the solutions either evaporate or solids condense in them. • Sedimentary rocks are made from sediments. • These sediments are weathered down pieces of other rocks that are then compacted and cemented together.
Wrap Up • How are clastic sedimentary rocks different from nonclastic sedimentary rocks? • Sedimentary rocks are made from sediments. • Clasticsedimentary rocks are composed of sediments that were either cemented or compacted (pressed). • Nonclastic sedimentary rocks are the result of evaporation or precipitation in a liquid.
