Sand drains too quickly. Clay is poor draining and is likely to be waterlogged. Potting soil is specially formulated to drain slowly, and contains humus and plant nutrients.

plants that like water grow better in clay and plant that don't like water grow better in sand. like cactus
Because soil has nutrients that clay and sand don't have
To make loamy potting soil, mix equal parts of sand, silt, and clay with organic matter like compost. This will create a well-balanced soil that is ideal for plant growth.
Beach sand can be in hottest condition but cannot hold it for long period. Dark soils such as potting soils can hold it for long time.

Potting soil is not typically considered sticky, as it is designed to have good drainage and aeration for plant roots. However, some potting mixes may feel slightly sticky when wet due to the organic materials used in the blend.
Potting soil absorbs the most water of your choices. One often adds perlite to potting soil to increase its drainage. Some people also like to put a layer of gravel at the bottom of their planter for this reason. Gravel has good drainage. The worst drainage is clay. Soil has several constituents. Hummus is organic matter high in nutrients and absorbent. The organic matter is important but it absorbs a lot of moisture which can lead to fungus. Sand or gravel increases drainage but alone is terrible quality soil because it has no mineral nutrients or organic matter. Clay is mineral rich but very dense. Water pools on top of it. It has terrible drainage and little organic matter. Poor soil is usually some mixture of sand and clay.
I am a ninth grader and I am doing an experiment on which type of soil sugarsnap peas will grow the best in. I'm using regular soil, potting soil, red clay, and sand. So far the potting soil has sprouted and none of the others have !
