Dynamic Earth Unit 1 Study Guide What are the 2 types of weathering? Define erosion CHEMICAL + PHYSICAL MOVEMENT OF SOIL FROM 1 PLACE TO ANOTHER What type of weathering is wind? PHYSICAL How does an alluvial fan form? STREAM SLOWS DOWN (FLAT AREA OF LAND) + DEPOSITS SEDIMENT OVER TIME How might erosion by groundwater create a landform? ACIDIC WATER DISSOLVES ROCKS UNDERGROUND TO FORM A CAVERN Where is a delta formed? WHERE THE RIVER ENTERS THE OCEAN How does the gopher tortoise cause physical weathering? IT MOVES ROCKS ABOVE GROUND WHERE IT IS EXPOSED TO WIND AND RAIN What usually causes a valley to first form? Define groundwater RUNNING WATER WATER BELOW THE EARTH’S SURFACE Define shoreline WHERE LAND AND A BODY OF WATER MEET Why is Loess valuable? FORMS GOOD SOIL FOR FARMING How is Loess formed? LAYERS OF WIND BLOWN DUST BUILD UP What landform is mainly created by erosion by groundwater? UNDERGROUND CAVERN What causes cracks in rocks to grow larger? PLANT ROOTS + ICE What mainly causes sand dunes? WIND What would happen if the slope of a stream was increased? WATER SPEED + EROSION INCREASE What force mainly causes landslides, rock falls, and mudslides? GRAVITY What weather condition mainly causes landslides, rock falls, and mudslides? RAIN How do decaying leaves affect rocks in the soil? RELEASE ACID INTO SOIL INCREASING CHEMICAL WEATHERING What is needed for kettle lakes to form? MELTING ICE BLOCKS + SEDIMENT What landform most likely formed beneath a sinkhole? `CAVE What removes the most sand from a barrier island during a storm? LARGE WAVES What causes granite to break down over time? RAIN + WIND What causes the deposition of sand at a delta? RIVER WATER SLOWING DOWN AS IT ENTERS THE OCEAN Define creep MASS MOVEMENT CAUSED BY GRAVITY What often happens to rock undergoing chemical weathering? IT CRUMBLES EASILY What happens to a rock when it is weathered? IT IS BROKEN INTO SMALLER PIECES What type of rock is most affected by acids? MARBLE Define abrasion A SHAPE CHANGE DUE TO EXPOSURE TO WIND / A CHANGE IN SIZE
