Which of the following statements describes how a rock changes after it is in a riverbed for a long time?
acids in the water react with chemicals in the rock.
deposition
an area with high winds, significant rain, hot summers, and freezing winters
flooding or a mudslide
The edges of the rock are worn away, so its surface becomes smoother
planting cover crops and employing contour plowing methods
The oxygen in the air combines with the elements in the rock in a process called oxidation (rust).
ice wedging as water seeps into cracks, freezes, expands, breaks rock apart, melts, and seeps deeper into the rock.
Which human activities can help prevent soil erosion?
