in my science book it says pebbles move .75 cm/sec
Grains of sand will move faster compared to pebbles. Sand is lighter and will easily get carried by wind, unlike pebbles, which are heavier in comparison.
Pebbles move primarily through the forces of water, wind, and gravity. In rivers and streams, flowing water can carry pebbles downstream, often causing them to roll or bounce along the riverbed. In coastal areas, waves can wash pebbles back and forth on beaches, while wind can displace smaller pebbles across dry surfaces. Gravity also plays a role, causing pebbles to slide down slopes or cliffs during landslides or erosion.
Grains of sand typically move quicker than pebbles due to their smaller size and lighter weight, which allows them to be easily lifted and carried by wind or water. In environments like beaches or deserts, sand can be shifted rapidly by the forces of nature, while pebbles, being larger and heavier, tend to remain in place or move more slowly. Thus, in general conditions, grains of sand will move quicker than pebbles.
In this scenario, water is the solvent, which is the substance that dissolves the other components. The pebbles are the solute, which is the substance being dissolved in the water.
In water fast, on land their slow.
"Go" where you have both black and white stone pebbles .
Filtration will separate the pebbles and water ... Pour the mixture through a strainer (or better yet, an old burlap bag) and catch the water in a bucket. The pebbles will remain in the strainer or bag.
A mixture of pebbles and water would be heterogeneous.
filter or decant leaving behind the pebbles. evaporate the water leaving behind the sugar.
Abrasion of rock and pebbles in fast-flowing streams is primarily caused by the mechanical scraping and grinding action of sediment and larger particles being carried along by the water. The swift current increases the energy of the flow, allowing these particles to collide with and erode the riverbed and bank materials. Additionally, turbulence in the water enhances the effectiveness of this erosion process, leading to the smoothing and rounding of rocks and pebbles over time.
the smaller they are the less resistance to water and the faster they move.
