Grass is a plant; it has roots. Lawns need about 1" of rain, or watering, a week. Deep water penetration helps roots grow down. Shallow water penetration helps roots grow sideways. Soil composition makes the water amount vary and shapes what direction roots will grow. If soil has a lot of clay water tends to run off. If soil is sandy water tends to soak in. Grass roots seek water and will grow down into a soil that is cared for. Grass that is uncared for tend to grow horizontally in a soil that is hard, clogged, and untended.
