Water At The Surface Of Earth

Water at the Surface of the Earth: An Introduction to Ecosystem Hydrodynamics provides an introduction to the ways in which biological, physical, cultural, and urban systems at the surface of the earth operate, with a particular focus on the hydrodynamics of ecosystems, i.e., water and its association with other forms of matter, including pollutants, and with several forms of energy. The chapter sequence in this book follows the downward progress of water from the lower atmosphere, through ecosystems at the earth's surface, through the soil and mantle rock, to the ""waters under the earth."" In other words, the book begins with input of water to ecosystems, then describes how it is processed in these systems, and ends with the liquid water yield from them. The book first discusses storms in the atmosphere. These are systems that convert inflows of water vapor into outflows of raindrops and snowflakes that are precipitated to the underlying surface. This is followed by separate chapters on how water is delivered from the atmosphere to surface ecosystems; water budgets at the surface and in the soil; evaporation from these systems back to the atmosphere; water in the local air and rocks; and horizontal movement of water transformed by ecosystems where the preceding storages and fluxes were located.

Water at the Surface of Earth.

Every raindrop, lake, underground river and glacier is part of a single global well. Discover the many ways water is used around the world, and what kids can do to protect it.

Earth's surface is constantly being changed by heat, water, ice, salt, plants, and animals. Sometimes the changes are destructive to human activities such as farming and the building of structures. This interesting title shows the different ways people try to stop or reduce this change in the land. Examples feature such structures as dikes to hold back water and windbreaks, and adding shrubs, grass, and trees to an area of land to prevent erosion. Teacher's guide available.

Water is one of the essential components necessary for life to exist on Earth. All of Earth's water in all its states, frozen, liquid, and gaseous, make up the hydrosphere. Liquid water exists on the surface of the earth but there are also reservoirs of water underground. Frozen water exists as glaciers, ice caps, and icebergs. This water makes up a special subcategory of the hydrosphere called the cryosphere. Water can even be found in the atmosphere in the form of water vapor. Readers will come to understand how the water cycle tracks water's movement from one phase to the next.
