What and where are the biggest sand dunes in the world?

It depends on the type of sand dune.

There are three contenders for the title of the world's biggest sand dune, and it depends upon the context - whether one means the highest in actual sand dune size, or the highest above sea level. According to some sources, the world's highest sand dune is the Cerro Blanco dune in the Sechura Desert, Nazca, Peru. However, according to the Namibian Ministry of Environment & Tourism, the highest dune in the world is called Big Daddy, or Dune 7, and is one of the Sossusvlei dunes in the Namib Desert. However, according to the website link below (Duneguide), the highest sand dune may well be the humble Mt Tempest on Moreton Island, just off the coast of southern Queensland, Australia. The second largest sand mass in the world, Mt Tempest reaches 280m above sea level.

The world's highest stationary dunes are the Badain Jaran dunes in the Badain Jaran Desert within the Gobi Desert in inner Mongolia.

The longest parallel sand dunes in the world are in Australia's Simpson Desert. Consisting of over 100 dunes, they run north-south, with some stretching as far as 200 km.

The largest crescentic sand dunes in the world are located in the Taklamakan Desert of China. These dunes have an average crest to crest width of over three kilometres.

How do you separate a mixture of sand and solid table salt?

Table salt is soluble so take the mixture and add water to it. The table salt will get dissolved. Now pour the whole mixture in a filter paper above a beaker. Now the residue above the paper is the sand, rinse it with additional water to remove the table salt on the sand grains. Now take the water in which the table salt is dissolved and heat it with a burner and the water will evaporate and leave the table salt behind. This is the best method to separate them.

How do sand dunes form?

Dunes are formed when wind and waves transport sand onto the beach. The ultimate source of the sand is often glacial till that resides offshore, or is eroded from nearby cliffs by waves, and transported along the shoreline by long shore currents (see coastal sediment processes). Rivers can also transport sand to the coast from inland deposits. Waves wash this sand up on the beach, and also remove it during storms.

Sand particles can be carried away by strong winds. These particles eventually fall when the wind if not strong enough to keep them aloft. Sand dunes form in areas where wind routine occurs. The dunes start when an obstruction of some sort acts as a barrier to block the wind. The wind slows down when it hits the barrier, allowing the sand particle to fall to the ground Eventually, the obstruction, which may be a stump or rock, will become completely buried by sand. The dune continues to grow by the same process as more and more sand particles are released by the winds that slow down when they hit the dune. Interestingly, dunes move slowly. This occurs when the wind lifts sand up on the windward side and the sand falls down on the leeward side.

Answer: It is formed because of wetness and the wind moving towards the sand dunes

What can cause a sand dune to slowly move in the direction of the wind?

winds that blow in a steady direction can move a dune . such wind will consistently pick up sand from one side and deposit it to a other side. this causes the entire dune to slowly move in the direction if the wind. :)

The parallel, wind-blown sand dunes that make up the spectacular parallel dunal desert occupy about 10 000 sq km of the entire desert, which is about 200 000 sq km in area. The remainder of the desert is sandy plains, spinifex grasslands, saltbush plains and salt lakes. If you would like more information, go to the related link below.
