Ocean Depth Zones
Your child knows the sea has layers by depth. The sunny top layer holds most life. Below it the light fades, and deeper still it is fully dark.
In curriculum terms
Understand that the ocean has different zones depending on depth and light: the sunlight zone near the surface where most life lives, the twilight zone where light fades, and the midnight zone of total darkness

If your child saw a diagram showing the ocean getting darker as you go deeper, could they name the three main zones and explain why most ocean animals live near the sunlit surface?
