sand
Sandy soil has large grains and allows water to drain easily due to its coarse texture and good drainage properties.
An impermeable layer underground that holds groundwater is called an aquifer. Aquifers are underground layers of rock or sediment that are saturated with water and have limited permeability, preventing water from easily flowing through them.

Sedimentary rocks tend to erode easily compared to other types of rocks as the grains within them are farther apart than the "grains" in, let's say, igneous rocks. As a result of this, the "grains" can be easily crumble. An example of this is sand.
YES! Sedimentary rocks, like sandstone, limestone and chalk can easily be eroded. This is because the grains in them (different to particles) are further apart to the grains in rocks like igneous rocks. This means that the grains can easily be crumbled off, and you get left with sand.
Small grains erode faster than big grains because small grains have a larger surface area relative to their volume, allowing more contact with flowing water or wind that can wear them away more quickly. Additionally, small grains are often lighter and more easily transported by wind or water, further contributing to their erosion.

A sponge holds the least amount of water compared to other household items. It is designed to absorb and release water easily.
The heads side of a penny holds more water because it has a slightly raised edge that creates a small barrier preventing the water from spilling over the sides. The tails side is flat and the water can easily spill off the edges.
salt does not disolve quickly in water because all the little grains are so small the have more suface area than air bubbles therefore the water takes longer to get into the grains of salt.
The water molecules are far smaller than the spaces between the sand grains and can easily slip through, gravity pulls the water down.

because sand has small grains and allows water to travel through it. Clay has smaller grains than sand and doesn't allow water to travel through it quickly.
Sand can stop water from flowing through by creating a barrier due to its dense and compact nature. The small particles in sand pack tightly together, which reduces the ability of water to pass through easily. The interlocking grains of sand create a barrier that slows down or prevents water from flowing through.
duckweed is small and can float easily
A reservoir is a big land mass that holds water "supplies" an aquifer is the same thing is just small and you could say that it purifies the water that it holds.
An impermeable layer underground that holds groundwater is called an aquifer. Aquifers are underground layers of rock or sediment that are saturated with water and have limited permeability, preventing water from easily flowing through them.
