i believe it take about ten years to form a sand dune
1'00000
Natural gas can take millions of years to form. It is created from the decomposition of organic matter, such as dead plants and animals, under high pressure and temperature deep beneath the Earth's surface.
I guess when heated molecules escape their liquid form
10,000,000+ years
BANANNA
about 10 years
a long, long time
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.
Factors that affect dune shape include wind direction and strength, sand supply, vegetation cover, and obstacles on the dune's path. Wind direction and speed determine the dune's asymmetry and orientation, while sand supply and vegetation influence the dune's stability and size. Obstacles like rocks or buildings can cause the dune to take on unique shapes as it flows around them.
It takes thousands of years to form because the rocks have to break down into little pieces.
ho long dose it take a humien to sink in quick sand
the dune gently move to the ocean
Sand dunes are formed on the coast when waves carry sand onto the shoreline and the wind blows it into drifts. The sand gets trapped on plants such as Sand Couch and Marram Grass and the embryo dunes start to grow. Marram Grass is one of the most important dune plants. It has long roots that grow down deeply in search of water. These roots help to hold the dunes together. Further inland the dunes are more stable and have lots of different plants, mosses and lichens growing on them. There can even be a very wet area. This is known as the 'dune slack' and rushes and reeds that like lots of water will grow here. Sand dunes are a very important habitat. They are also a popular place for people to visit. However they are very fragile environment and changes can take place quickly. To protect the dunes plants from being trampled too much, special wooden paths called 'boardwalks' are put down for people to walk on.
a million years
I didn't think that pumkins grew in sand but if they do thats cool :}
if it is wet take out the wet sand you can sift and reuse sand but 5 times max
A couple minutes
