Question

1. Why is the sea shore sandy?​

Answer 1

Answer:

Sand on beaches around the world comes from the weathering and pulverization of rocks over millions of years, along with fragments of shelled creatures and coral and that have been deposited on the coast by the waves.

The sand on most beaches around the world is formed from the minerals quartz and feldspar. These minerals, in turn, are formed as a result of millions of years’ worth of weathering and eroding of igneous and metamorphic rocks (although feldspar is also found in some sedimentary rocks).  

Contrary to what one might believe, not all rocks are made equal when it comes to strength and durability. Some minerals are unstable and decompose, while others are more resistant to erosion and therefore more likely to persist. Quartz and feldspar are examples of such minerals. So, one way that so much sand ends up on beaches is by way of millions of years’ worth of weathering of rocks that are abundant in Earth’s crust.

In addition to that, flowing rivers also continuously erode the land (rocks and other materials), which breaks down rocks into tiny, sand-sized particles.
