Water for Life

Water is essential for life on land. Water works in concert with ground cover to maintain a stable, self-sustaining foundation for the terrestrial ecosystem. Water is absorbed and held by soil. That soil in turn gives root to plants that bind the soil together and prevent it from being washed away by wind and rain. With the coming of the warmer climates of the Silurian Period, Earth regained its temperate and tropical zones. This encouraged the growth and spread of ground cover and soils. Rainfall nourished newly formed soils and spurred the rapid radiation of plants during the Silurian Period.
