Are you a student of geology? How much do you know about saltation? Will you be able to pass this saltation quiz? In geology, the meaning of saltation is a specific type of particle transport that happens by fluids such as wind or water. It comes to existence when loose materials are removed from a bed, and then they are carried by the fluid before they are transported back to the surface. Let's learn even more about these questions.
How much salt is in the water
The movement of sand along the shoreline
The effect of salt spray on barrier island plants
Saltation is the movement of sand by 10 mph or greater winds that create a dune.

Rate this question:
Surface creep occurs when saltating grains of sand strike heavier grains larger than one millimeter in diameter, causing the heavier grains a slight forward movement along the surface.
Surface creep occurs when saltating grains of sand strike finer grains smaller than one millimeter in diameter, causing the finer grains a slight forward movement along the surface.
Surface creep occurs when saltating grains of sand strike heavier grains larger than one millimeter in diameter, causing the finer grains a slight forward movement along the surface.
Surface creep occurs when saltating grains of sand strike heavier grains larger than one millimeter in diameter, causing the heavier grains to suspend in the air from their movement along the surface.
Rate this question:
Waves deposit the fine sand onto the dune.
Saltation carries only the finest of beach sand.
Saltation mixes salt with sand making it finer.
Fine sand is more porous.
Rate this question:
The fluid threshold is the wind speed necessary for sand to start saltating under the direct pressure of the wind.
The fluid threshold is the wind speed necessary to maintain saltation once it has begun.
The fluid threshold is how all the surfaces respond to each other as they move.
The fluid threshold is wind speeds above 20 mph that occur above the windy side of a dune.
Rate this question:
Sand tends to accumulate in any place where there is a sufficient reduction of wind energy in the direction that sand drifts in, and any obstacle, such as a rock outcrop or a stand of vegetation, forces sand accumulation by lowering the wind speed.
Sand tends to accumulate in any place where there is an abundant wind velocity in the direction that sand drifts in, and any obstacle, such as a rock outcrop or a stand of vegetation, forces sand accumulation by lowering the wind speed.
Sand tends to accumulate in any place where there is a sufficient reduction of sand in the sand drifts in, and any obstacle, such as a rock outcrop or a stand of vegetation, forces sand accumulation by sustaining the wind speed.
Sand tends to accumulate in any place where there is a sufficient reduction of sand in the sand drifts in and any obstacle, such as a rock outcrop or a stand of vegetation, forces sand accumulation by lowering the wind speed.

For dune formation to occur the following is required: a large supply of sand, wind speeds capable of moving sand, and an ideal location for sand to accumulate.
For dune formation to occur, the following is required: a large supply of sand, wind speeds capable of moving sand, and a shoreface that extends from the near shoe sandbar to the berm.
For dune formation to occur, the following is required: a large supply of sand, wind speeds greater than 20 mph, and a shoreface that extends from the near shoe sandbar to the berm.
For dune formation to occur, the following is required: a large supply of sand, wind speeds less than 10 mph, and a shoreface that extends from the near shoe sandbar to the berm.

Saltating sand grains strike heavy grains of sand on the surface. These saltating grains don't have enough energy to knock the heavier grains into the air. The saltating grains cause the heavy grains to move slightly forward or "creep" along the surface.
Saltating sand grains strike fine grains of sand on the sand surface. These saltating grains have enough energy to knock the fine grains into the air. These fine saltating grains cause the heavy grains to move slightly forward or "creep" along the surface.
Saltating heavy grains of sand "creep" along the surface. These heavy saltating grains have enough energy to knock the heavier grains forward or along the surface.
Storm winds carry heavy grains of sand along the surface. Heavy grains saltate during storms. They move slightly forward or "creep" during a storm.
