Please list as many as you can think of. (It is revision for my geography test tomorrow. 10 points for best answers)
Example:
Beach are formed by deposition but headland and bay are formed by deposition and erosion.
Answer
A headland is a point of land, usually high and often with a sheer drop, that extends out into a body of water. The word is often used as a synonym for promontory. A headland is often referred to as simply a head, either in context or in names such as Beachy Head or Koko Head. Gibraltar is a headland
http://en.wikipedia.org/wiki/Headland#List_of_some_well-known_headlands --------
Headlands and bays are often found together on the same stretch of coastline. A bay is surrounded by land on three sides, whereas a headland is surrounded by water on three sides. Headlands are characterized by high, breaking waves, rocky shores, intense erosion, and steep sea cliffs. Bays generally have less wave (and often wind) activity than the water outside the bay, and typically have sandy beaches. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form where weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, granite) forming a headland, or peninsula. This difference in the rate of erosion is caused by differential erosion. Refraction of waves occurs on headlands concentrating wave energy on them, so many other landforms, such as caves, natural arches and stacks, form on headlands. Wave energy is directed at right angles to the wave crest and lines drawn at right angles to the wave crest (orthogonals) represent the direction of energy expenditure. Orthogonals converge on headlands and diverge in bays which concentrates wave energy on the headlands and dissipating wave energy in the bays. In the formation of sea cliffs, wave erosion undercuts the slopes at the shoreline and they retreat landward. This creases the shear stress in the cliff-forming material and accelerates mass movement. The debris from these landslides collects at the base of the cliff and are also is removed by the waves, usually during storms where wave energy is greatest. This debris provides sediment, transported through longshore current for the nearby bay. Joints in the headlands are eroded back to form caves which erode further to form arches. These gaps eventually collapse and leave tall stacks at the ends of the headlands. Eventually these too are eroded by the waves. Wave refraction disperses wave energy through the bay, and along with the sheltering effect of the headlands this protects bays from storms. This effect means that the waves reaching the shore in a bay are weaker than the waves reaching the headland and the bay is thus a safer place for water activities like surfing or swimming. Through the deposition of sediment within the bay and the erosion of the headlands, coastlines eventually straighten out then start the same process all over again.More....
http://en.wikipedia.org/wiki/Headlands_and_bays --------- A beach is a geological landform along the shoreline of an ocean or lake. It usually consists of loose particles which are often composed of rock, such as sand, gravel, shingle, pebbles, waves or cobblestones. The particles of which the beach is composed can sometimes instead have biological origins, such as shell fragments or coralline algae fragments.
Wild beaches are beaches which do not have lifeguards or trappings of modernity nearby, such as resorts and hotels. They are sometimes called undeclared, undeveloped or undiscovered beaches. Wild beaches can be valued for their untouched beauty and preserved nature. They are most commonly found in less developed areas such as Puerto Rico, Philippines, Thailand or Indonesia.
Beaches often occur along coastal areas where wave or current action deposits and reworks sediments.More............ http://en.wikipedia.org/wiki/Beach

What are some good public family beaches in San Diego?
Uncle Penn
Will be traveling to San Diego in August with my 4 year old. Would like to visit a couple of beaches. Nothing special, just fun in the sun on the sand and in the waves. Easy parking is a plus.
Something sheltered from a lot of wind, or where the sunset doesn't blaze directly in your eyes as you look out toward the water would be nice too.
Thanks for your help.
Answer
La Jolla shores is really nice! The cove (about a mile away) and tip of La jolla that sticks out, helps to shelter from huge waves and rough water so its not as scary as other beaches ( when watching small children) There is also a little park and playground right there.
