The deserts and dunes seen here are created through the process of Weathering and Erosion.
Weathering is defined as the process of breakdown of rocks, soil and minerals into small particles under the influence of atmosphere, water and also biological organisms to some extent. The products of weathering are found at same place as the original rock with little or no movement.
In erosion, the materials such as rocks and soil or dissolved materials are transported from one place to the another place by the action of wind or water flow. So, here displacement of substances takes place.

<h2>Vegetarians, especially vegans, need to consume adequate amounts of the essential amino acids by choosing complementary proteins and eating plant sources of complete protein like soy and quinoa.</h2>
Explanation:
Vegetarian diet does not contain all the essential amino acids. Amino acids are of two types, essential and non- essential amino acids. The essential amino acids are not synthesized by our body so we must have to take these essential amino acids through food. So vegetarians, especially vegans, need to consume adequate amounts of the essential amino acids by choosing complementary proteins and eating plant sources of complete protein like soy and quinoa.
