The wind influences the shape and size of a sand dune.
Is it true wind direction influence the shape and size of a sand dune?
no
What is the size and shape of a sand dune?
Sand dunes have a million shapes and even change as you look at them.
What can the size of a sand dune tell you about how it was formed?
If the sand dune is big, there must have been strong winds and big waves in the area. If the sand dune is small, there must have been little wind and waves in that area.
What and where are the biggest sand dunes in the world?
There are three contenders for the title of the world's highest 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, and it is all sand.
Why do sand dunes change shape and size every year?
They change shape every time the wind blows.
Are all grains of beach sand the same?
No. They vary widely in size, shape and composition.
Name 4 details that you can observe to help learn about an animal that made a track in the sand?

I would say that it probably depends on the size of the dune. It would take longer to walk across a high dune than it would to cross a low dune.
What are the phyical properties of sand?
Sand has several physical properties. Some of the most important are porosity, mineral composition, grain size, grain shape, and permeability.
How can you show that sand does not take the shape of it's container?
pour in water. The water will fill in the space that the sand is leaving open. This "open area" would not exists if the sand was taking the shape of it's container. alternately, use a bunch of marbles. Sand is not much different then a marble other then in size. The marbles can show on a larger scale what is happening with the sand.
Is determined by the angle of repose for dry sand?
Yes, the angle of repose for dry sand is the maximum angle at which sand can remain stable without collapsing. It is influenced by factors such as grain size, shape, and moisture content, and can vary depending on the specific characteristics of the sand material.
