Erosion changes landscape by rain,ice,water.
All the mentioned process work to change the course of the river, deepening valleys, and carrying sediment to lakes, seas and oceans.
Frequency and wavelength are inversely proportional. The greater the frequency, the shorter the wavelength. The lower the frequency, the longer the wavelength.
The frequency of a wave change as its wave length changes by a longer wave length and has a lower ferquency.
