Introduction to rain Rain is liquid water in the form of droplets that have condensed fromatmospheric water vapor and then precipitated—that is‚ become heavy enough to fall under gravity. Rain is a major component of the water cycleand is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystem‚ as well as water for hydroelectric power plants and crop irrigation. The major cause of rain production is moisture moving along three-dimensional

2009)‚ thirteen species were studied of Spartina ranging high to low marsh and freshwater habitats. The scientists studying Spartina grasses used light and electron microscopes to measure and record the number of stomata on the adaxial side of the leaf. Thirteen species were collected and examined: Spartina alterniflora‚ Spartina anglica

Florida’s springs provide natural‚ recreational‚ and economical benefits for both the human life and the many different species that occupy such beautiful nature. In Florida‚ there are an estimated amount of 700 springs‚ which represents the largest concentration of freshwater springs on Earth.

The word ecosystem refers to the combined physical and biological components of an environment; these organisms form complex sets of relationships and function as a unit as they interact with their physical environment. Ecosystems are constantly changing naturally‚ and they’ve got a specific and stable climax‚ equilibrium.

1) In this article the author talks about impacts on civilizations from small and large climate changes. We have had several small climate changes in our past that affected agriculture‚ trade routes‚ and the types of products and commodities that sell. These things are occurring still to this day. But‚ larger climate changes have done a lot more damage in the past. They have cause the rise and fall of whole societies. For example‚ the Mayan Empire. It was believed to have fallen from decades of drought

Green algae have many similarities to land plants. It has many variety body types and the multicellular forms do not have cells separated into tissues‚ which is what divides green algae from land plants. Green algae are a very diverse group of freshwater algae. Many green algae form long filaments. The cells stay attached after they divide. Spirogyra can become so numerous they form dense mats of growth in surfaces of ponds‚ which is called pond scum. This pond scum is interesting to see through

Wetland Classification National Wetlands Classification Standard 4 goals: To provide a standard way of describing ecological units To characterize units in a frame work that will aid in natural resources management Identify classification units for inventory and mapping Provide uniformity in concepts and terminology Wetlands assigned a code‚ e.g. L1UB1Hx Broadest classification describes the system level The term system refers here to a complex of wetlands and deepwater habitats that share the influence
