To solve the problem, we need to identify the cause-and-effect relationships in the context of the text "Into the Sea." Let's analyze each row step by step:
---
Row 1:
-
Cause: Waves take away the sand between the houses and the sea.
-
Effect: This describes what happens as a result of the cause. When waves erode the sand, they weaken the foundation between the houses and the sea. The effect is that the land becomes unstable, and eventually, the houses may be at risk of falling into the sea or being damaged.
Effect: The land between the houses and the sea becomes unstable, putting the houses at risk.
---
Row 2:
-
Effect: Cliffs become weak and can crumble and fall into the sea.
-
Cause: This describes why the cliffs are becoming weak. Typically, cliffs weaken due to natural processes like erosion caused by wind, rain, and especially waves. Over time, these forces wear away the cliff face, making it unstable.
Cause: Waves continuously hit the base of the cliffs, causing erosion.
---
Row 3:
-
Cause: Some towns have built seawalls of large boulders or rocks.
-
Effect: This describes the outcome of building seawalls. Seawalls are constructed to protect the land from erosion caused by waves. By blocking the waves, the seawalls help stabilize the shoreline and prevent further loss of sand or soil.
Effect: The seawalls protect the land from erosion, stabilizing the shoreline.

Final Answer:
\[
\boxed{
\begin{array}{|c|c|}
