The gentle slope is in the upwind direction. The downwind direction has a steep slope called a slip face.

The steep face of a sand dune is called the slip face or the lee side. It is typically located on the leeward side of the dune where the wind direction forces the sand to accumulate in a steep slope. This portion of the dune is constantly shifting and changing due to the interaction of wind and sand movement.
Beyond the continental shelf, the seafloor drops off abruptly into the deep ocean, forming the continental slope. This slope extends down to the abyssal plain, which makes up a large part of the ocean floor. The abyssal plain is characterized by flat, sediment-covered expanses that are home to a variety of deep-sea organisms.
A raised part of the earth's surface smaller than a mountain is called a hill. Hills are elevated areas that are lower in altitude and size compared to mountains, and they are characterized by a gradual incline or slope.
A continental margin is NOT a part of a continent. It is the submerged outer edge of a continent that includes the continental shelf, continental slope, and continental rise.
The erosional part of a continental margin is the part closest to the shore where erosion processes such as wave action, currents, and weathering shape the coastline and remove sediment. This area is typically characterized by cliffs, beaches, and sediment transport towards deeper water.
The part of the continent that is underwater is called a continental shelf. It is the shallow, submerged edge of a continent that extends from the shoreline to a steeper drop-off called the continental slope.
