Answer:
The correct answer is A. Barrier islands are constantly moving in the direction of the longshore drift.
Explanation:
Barrier islands are islands in the form of relatively narrow strips of sand located close to and parallel to the coast of the mainland. As a rule, they are located in the form of a chain consisting of several islands, sometimes more than a dozen. The length and width of the barrier islands are related to coastal parameters, including tides, wave energy, sea level and soil composition. Some barrier islands reach a length of more than one hundred kilometers, the longest and widest is Padre Island, Texas. The shape, area and the very existence of barrier islands are variable, as they can appear and disappear in a short time on a geological scale.
These islands are formed from the longshore drift, which is forming these islands by sediment and sand accumulation. Therefore, as they are formed by this process, it is the same process that constantly moves them.
Answer: Partial melting
Explanation: Partial melting occurs when the temperature is high enough to melt some of the materials that make up a rock but not all. This happens because a rock is not made up of a single material but different materials which have different melting points.
As the molten or melted rock cools down it crystallizes in a process known as fractional crystallization and this is how igneous rocks are formed.

The sand on our beaches in California primarily originates from the Granites of the Sierra Nevada mountains
What are Granites?
The igneous rock known as granite has light-coloured granules that are large enough to be seen by the eye. It is created when magma beneath the surface of the Earth slowly crystallises.
Quartz and feldspar make up the majority of granite's chemical makeup, with only trace amounts of mica, amphiboles, and other minerals. Granite typically has a red, pink, grey, or white appearance due to its mineral makeup, with black mineral grains visible throughout the rock. The most well-known igneous rock is granite. Granite is the most prevalent igneous rock on Earth's surface, and since it is used to build so many items in daily life, it is widely recognised. These include stair treads, floor tiles, curbing, paving stones, countertops, building veneers, and gravestones. Granite is used everywhere.
