Antarctica is the fifth largest continent in the world. The word Antarctica is derived from the Greek word antarktike, which means “opposite to the north” i.e., opposite to the Arctic. It covers an area of 13,209,000 sq km which constitutes 8.9 percent of the earth’s land. It is the coldest and windiest spot on the planet. In fact, It holds the record for the lowest temperature on Earth -89.2 ºC. The mean winter temperatures range from -40 ºC to -70 ºC, and winds are commonly measured at up to 200 miles per hour.

Introduction

Dust and Sand

The terms dust and sand usually refer to solid inorganic particles that are derived from the weathering of rocks. In the geological sciences, sand is defined as mineral (i.e. rock derived) particles with diameters between 62.5 and 2000 µm, whereas dust is defined as particles with diameters smaller than 62.5 µm (note that the boundary of 62.5 µm differs depending on particle size classification schemes). In the atmospheric sciences, Dust is usually defined as the material that can be readily suspended by wind whereas sand is rarely suspended and can thus form sand dunes and ripples, which are collectively termed bedforms.¹²
