1 How Water Shapes our Landscapes and Shorelines Canyons Caves Direct Shorelines - Sandy vs. Stony Beaches Direct Shorelines - Mudflats Direct Shorelines - Promontories/Headlands (and Sea Stacks) Water can shape our landscapes in many different ways. Some of these ways include The two main factors influencing the appearance of shorelines in particular are tides and waves.

27 Recap: How Waves and Tides Affect Shorelines Water shapes our landscape in many different ways (types of beaches, canyons, caves, sea caves, sea stacks, hoodoos, etc). Tides and Waves are the two biggest influences on our shorelines. Tides and waves cause the processes of erosion and deposition along shorelines. Some examples: EROSIONDEPOSITION 1) Sea Caves (caused by the continuous crashing of waves against cliffs, wearing away the rock) 1) Sandy beaches (caused by small waves) vs. Stony beaches (caused by large waves) 2) Sea Stacks (similar to sea caves, but after longer periods of time) 2) Promontories/Headlands caused by the deposition of sand over time 3) Cliffs becoming smaller/shorter, which can sometimes affect housing 3) Algae, shells, seaweed, etc found on beaches
