Answer:
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
Explanation:
Erosion can be defined as a geological process which involves the wearing away of earth material and transportation of these material to another location by Natural agents such as wind and water. Erosion involves removal of top soil, rocks and other earth particles by action of wind, glacier and water.
Wind causes erosion by deflation. Deflation is the actual removal of grain of rocks . Generally, it s the lowering of land surface that happens as a result of removal of surface particles(sands grains) by wind. Deflation is usually prevalent in arid areas. This sand can later be picked up and deposited to form sand dunes . Sand dunes are mounds of sand formed by wind . This sands are sheltered by an obstacle. And sand dunes are prevalent in desert and or along the beach. The sand dune grows as sand accumulate.

When an element shares electrons with other atoms of the same or different elements to acquire stable electronic configuration, it is called covalency. If an atom shares 1 electron, its covalency is equal to 1. ... It needs 3 electrons to complete its octet.
The correct answer is - intrusive rocks.
The intrusion is a process in which the rising magma in the Earth's crust, manages to break through pre-existing layers of rock, and after that cool off, solidify, and create new intrusive igneous rocks. By doing so, the magma is breaking up the layers of rocks, thus the intrusive igneous rocks that are forming from it, come to be inside totally different rock units. The intrusions are always happening inside the crust, and the rocks formed from them are igneous rocks that have large crystals because of the slow cooling off of the magma.
