What is the earths surface from edge of a continent to deep part ocean?

Continental shelf extends from the edge of a continent to the point where the ocean floor descends rapidly. It is typically shallow, with an average depth of 130 meters (427 feet). The continental shelf is usually covered with sediment that has been eroded from the continent and deposited by waves and currents.

Continental slope is the steep incline that connects the continental shelf to the ocean floor. It typically has a gradient of between 2 and 5 degrees. The continental slope is often covered with sediment that has been deposited by avalanches and landslides.

Abyssal plain is the flat, sediment-covered ocean floor that lies at a depth of between 4,000 and 6,000 meters (13,123 and 19,685 feet). The abyssal plain is the largest landform on Earth, covering over 50% of the planet's surface.

Oceanic trench is a deep, narrow valley in the ocean floor that is formed by the subduction of one tectonic plate beneath another. Oceanic trenches are the deepest parts of the ocean, with the Mariana Trench in the Pacific Ocean being the deepest point on Earth at 10,902 meters (35,774 feet) below sea level.
