True or False: Shorelines with large tidal ranges can drastically change their image on RADAR between low and high tides.

The statement is true because shorelines with large tidal ranges experience significant changes in water levels between low and high tides. This variation causes substantial alterations in the visible features of the coastline, which can be effectively captured by RADAR systems. At low tide, areas that are usually submerged may be exposed, revealing different landforms, vegetation, and potentially man-made structures. Conversely, at high tide, these areas become covered by water, changing the RADAR return signal and presenting a different image.

The impact on the RADAR image is especially pronounced in regions where the topography and morphology of the seabed can influence how the water interacts with the shore. As a result, the RADAR can detect and display significant differences in the landscape based on the tide levels, thereby allowing users to observe the dynamic nature of the shorelines.

In contexts where tidal changes are less pronounced, or where specific RADAR types might not be sensitive to such variations, the effect may not be as significant. However, in general coastal navigation and monitoring scenarios, the substantial differences in shoreline appearance on RADAR during varying tidal conditions underscore the importance of accounting for tidal ranges in navigation and coastal management.
