It means, "As things became more clear"... similar to the visual change that occurs when a cloud of sand blocks one's view and then recedes, allowing what couldn't be seen to suddenly be seen.
Boulders settle first, followed by pebbles, then sand. This is because boulders are the heaviest and tend to settle fastest, while sand is the lightest and takes longer to settle.
Sand would settle first, as it has the smallest particle size and can easily compact together. Boulders, being the largest, would settle last due to their size and weight. Pebbles would settle between sand and boulders in terms of settling time.

When you mix sand and water, the sand particles will typically settle at the bottom of the container due to their higher density, while the water will form a layer on top. This physical separation occurs because sand is insoluble in water. Stirring the mixture can temporarily suspend the sand particles in the water, but they will eventually settle back down due to gravity.
The settling rate of the sand particles and the flow velocity of the stream are the two main factors that determine when the sand will settle out of the stream. Higher settling rates and lower flow velocities typically lead to quicker settling of the sand particles.
Letting the sand settle at the bottom of the beaker helps separate it from the solution, reducing the risk of contaminating the solution with sand particles. This step allows for cleaner and more accurate transfer of the solution into another beaker for further processing or analysis.
An iron filings and sand mixture is a suspension because the particles are large enough to settle out over time due to gravity. In a solution, the particles are uniformly distributed and do not settle.
if you really think about it....its obviously the winds Answer: Westerly winds from the region around Cape Verde can carry Saharan sand to Puerto Rico
In this scenario, the gravel will settle out first, followed by the sand, and then the clay. Gravel has the largest grain size and weight, so it will settle out of the water column first. Sand will settle out next, followed by clay, which has the smallest grain size and weight.
What you do is you face the block of sand(if it is under you hold down) then press R and it will disappear in a cloud of sand. You cannot do this for the white sand blocks.
