  • Question 8
    180 seconds
    Q. Sarah does the investigation described below using a model to study how rivers erode earth materials.
    ·  She pours 600 mL of sand onto a plate.
    ·  She pours 150 mL of water onto the pile of sand.
    ·  She measures how much of the sand washes off the edge of the plate.
    ·  She notices that less sand washes off the plate when she pours water slowly than when she pours it faster.
    How is the model similar to real rivers eroding earth materials?
    answer choices
    The model shows that faster-moving water makes sand stick to the bottom of a river.
    The model shows that slower-moving water makes sand float to the top of a river.
    The model shows that slower-moving water erodes less earth materials than faster-moving water.
    The model shows that faster-moving water erodes less earth materials than slower-moving water.
