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.
Water typically passes through sandy soil faster than through clay soil due to the larger pore spaces between sand particles. Clay soil has smaller pore spaces, resulting in slower drainage and water movement.
Water passes through clay slowly because clay particles are very small and closely packed together, creating a fine network of pores. These pores restrict the flow of water, causing it to move through the clay with difficulty. Additionally, clay is highly cohesive and has a high water-holding capacity, further impeding water movement.
Water passes through pebbles because they have larger gaps between them, allowing water to flow through. Clay, on the other hand, has smaller gaps between its particles, making it less permeable to water. This results in water being unable to pass through the clay surface easily.
plants that like water grow better in clay and plant that don't like water grow better in sand. like cactus
Clay has a higher surface area and increased binding capacity, allowing it to hold more water than topsoil and sand. The small particle size and microscopic pores in clay soil help to retain water through adhesion and cohesion forces, making it more effective at absorbing water. Sand, on the other hand, has larger particles and gaps between them, leading to less water retention capability compared to clay.
The time it takes for water to seep through clay can vary depending on factors like clay composition, thickness, and compaction. Generally, it could take from hours to days for water to seep through compacted clay, while in less compacted clay, it may take minutes to hours.
In clay soils are very small gaps between the rock particles, and so clay soils do not drain well. In sandy soils there are bigger gaps between the particles, allowing the soil to drain well and contain enough air.
Clay has very small pore spaces
The speed at which water flows through clay soil can vary depending on factors like clay particle size and compaction. Generally, water flow through clay soil is slower compared to sandy soil due to the smaller pore spaces in clay. The flow rate could range from very slow to moderate.
Water does not easily pass through clay because of its fine particle size and molecular structure, which create a dense, compact barrier that restricts the flow of water molecules. This results in clay having low permeability and high water retention properties.
because it is dense
Water moves slowly through clay soil because clay particles are very small and close together, creating a tightly packed structure with small pore spaces. This structure restricts the movement of water and makes it difficult for water to flow freely through the soil. Additionally, clay has a high water holding capacity, so water tends to be retained within the clay particles rather than moving down quickly.
