Ocean Features and Depths

Miss Hini introduces ocean features, focusing on the ocean floor's varying depth and environment. She explains how temperature, light, pressure, and salinity change with depth. The video covers major geographic features like the continental shelf, slope, rise, abyssal plain, and ocean trenches, highlighting the Mariana Trench as the deepest. The video concludes with acknowledgments.
