Sediment falls to the bottom of the ocean over a long period of time forming layers (stratification). The layers compact and cement into rock that contains seashells. What kind of rock has formed?
flooding or a mudslide
sedimentary
acids in the water react with chemicals in the rock.
humus
an area with high winds, significant rain, hot summers, and freezing winters
deposition
ice wedging as water seeps into cracks, freezes, expands, breaks rock apart, melts, and seeps deeper into the rock.
The oxygen in the air combines with the elements in the rock in a process called oxidation (rust).
A delta is where a river empties into the sea and dumps its load of silt. A famous delta is found in Mississippi. The process of dumping silt is called
