In sea coasts, an inlet usually refers to the actual connection between a bay and the ocean and is often called an "entrance" or a recession in the shore of a sea, lake, or river. A certain kind of inlet created by glaciation is a fjord, typically but not always in mountainous coastlines and also in montane lakes.  - Mexico (, modern Nahuatl ), officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost two million square kilometers (over 760,000 sq mi), Mexico is the sixth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous country and the most populous Spanish-speaking country in the world while being the second most populous country in Latin America.

Geomorphologists seek to understand why landscapes look the way they do, to understand landform history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field.  - Southern California, often abbreviated as SoCal, is a geographic and cultural region that generally comprises California's 10 southernmost counties. The region is traditionally described as eight counties, based on demographics and economic ties: Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, and Ventura. The more extensive 10-county definition, which includes Kern and San Luis Obispo counties, is also used based on historical political divisions. Southern California is a major economic center for the state of California and the United States.  - A coastline or a seashore is the area where land meets the sea or ocean, or a line that forms the boundary between the land and the ocean or a lake.

The Cove is protected as part of a marine reserve ; underwater it is very rich in marine life , and is popular with snorkelers , swimmers and scuba divers . The swells that often roll in from the open ocean here can be rather large and strong , and so being in the water at the Cove is not always suitable for people who do not have good water skills . The water temperature is also often a little colder than the average San Diego beach , and the beach has the disadvantage that the dry sand area is very small at high tide . In contrast , during very low tides , a lot of interesting tide pools are revealed at the Cove .  - Baja California, officially the Free and Sovereign State of Baja California, is a state in Mexico.
