Final answer:
Waves reaching the shore, density, temperature, and light in aquatic systems, and different types of ecosystems are examples of how Earth systems converge at the shore.
Step-by-step explanation:
When waves reach the shore, the water depth decreases and the wave energy is compressed into a smaller volume, creating higher waves, which is known as shoaling. This convergence of waves at the shore is one example of how the Earth systems converge.
Another way the Earth systems converge is through the interaction of density, temperature, and light in aquatic systems. Different zones are formed based on water depth and distance from the shoreline, supporting different kinds of organisms adapted to each zone.
Coral reefs, estuaries, and freshwater biomes are all examples of how different Earth systems come together at the shore.
