Over time sediment drops into a new place. When sediment is dropped it is called ______. Deposition A crack in a rock has filled with water. What might happen if the water freezes? The rock will crack What feature is produced by deposition? Delta If a rock has been weathered by moving water, how will the rock look and feel? Worn down and smooth Loose material that covers much of the Earth’s surface is called: Soil ________ is the decayed remains of plants and animals Humus The MOST humus is found in which layer of soil? Topsoil List and describe the three layers of soil. Topsoil- a lot of humus Subsoil- bottom layer of soild, not much humus Bedrock- bottom layer of rock Which type of soil has the largest particles? Sandy The preserved remains of a plant or an animal that lived long ago are _____________. Fossils What is the first step in how a fossil is formed? A living thing dies What can fossils tell paleontologists about organisms that lived long ago? 1. They can tell paleontologists what type of climate the organism lived in- hot or cold 2. How large the organism was 3. What type of food the animals ate. Which type of fossil is formed from a mold? Cast Petrified fossils are formed when wood turns into ________ Rock A fossil imprint of an animal that lived long ago is not likely to give clues about the animal’s: A. shape B. color C. size D. weight B. color Why can water pass easily through sandy soil? the particles are bigger A _______________ is a scientist that studies fossils. Paleontologist Which type of soil has the smallest particles? Clay Which is an example of erosion? A. wind moving sand from a dune B. plant roots splitting apart a rock C. large rocks wearing down A. wind moving sand from a dune . ___________ is the slow breaking apart or wearing away of rock into smaller pieces. Weathering List the four causes of weathering. Wind, Water, Ice, Roots List the four causes of erosion Wind, Water, Glacier, Gravity Which MOST LIKELY made this fossil? A. a sea creature B. a bone C. a plant A. A sea creature Which is NOT a cause of erosion? A. glacier B. bright sunlight C. moving water B. Bright sunlight Final Jeopardy Question If a paleontologist finds a fossil of a fish on top of a mountain, she can infer that the are was once: Underwater
