WATER -K.S. Are you ready to get this party started? -T of C Let’s Go! We will know how Erosion and Deposition affects the Earth’s surface.

EROSION The transportation of material by water, wind or ice is known as Erosion. Naturally occurring erosive rainfalls or windstorms can make erosion a huge environmental issue. The effects of erosion impact two places, on-site which is where the soil has become detached and off-site which is where the eroded soil goes. erosion goes through a process which is detachment, entrainment and transport. Excessive erosion can produce trouble such as ecosystem damage, loss of soil and receiving water sedimentation. The effects of erosion is sometimes linked to overpopulation.

DEPOSITION The process by which water vapor is changed directly to a solid without passing through the liquid state is known as deposition. An example of this would be, sub-freezing air or water vapor changes directly to ice. This is how snow forms in clouds, as well as frost on the ground or your windshield. Deposition goes through a cycle and the cycle is, entrainment, transport and finally deposition. Causes of deposition are precipitation and flocculation both of the processes are active ONLY IN WATER.

Other Examples:

THE WATER CYCLE The water cycle is a result of a collection of connected processes that distributes water and energy throughout the Earth’s system in cyclic patterns. Processes include freezing, melting, correction currents and infiltration. Transportations include evaporation, precipitation, condensation and collection.

KEY TERMS Condensation: Water vapor in the air gets cold, changes into liquid forming clouds. Precipitation: when so much water has been evaporated into clouds that it can no longer hold, then the water falls back to the Earth as rain, hail, sleet or snow. Evaporation: when the water turns into vapor due to heat and rises to form clouds. Collection: collected bodies of water. (ex. Oceans, rivers, lakes etc.)

The four studies in mineral and rock resources include: Igneous, sedimentary, metamorphic and weathering. – Metallic-gold, platinum, silver, copper, iron, etc… – Nonmetallic-diamonds, gems, salt and other precious sources. – Rocks-marble, granite, sand and gravel.

Day 2 WWK: we will know the level at which water is maintained with in the eco system

WATER TABLE The level at which water is maintained with in the ecosystem Sea mount-is an Isolated peak that rises at least 1000 meters above the ocean floor Rapid-a channel of water moves swiftly

WET LAND A general term covering all shallow aquatic ecosystems(fresh water and marine)together with marshes swamps fens and bogs Interior drainage-pattern of streams that don’t lead to the ocean Sea wall-barrier constructed to prevent waves from reaching the area behind the wall

WWK: How water works in its cycles around ecosystems and the world.

Hydrology- the study of the movement of water in its cycles around ecosystems and the world. Humans have altered wetland hydrology through a variety of activities: drainage, filling, damn construction, water diversions, groundwater pumping, and dredging

Run offs have been created from this, which is altering cycles around certain places of the world.

Key Terms Hydrology- the study of movement of water in its cycles around ecosystems and around the planet. Run off- Water that flows over the land rather than infiltrating into the ground

WWK the uses and power that water brings as well as its destructiveness

Power Water has many varying applications. The many aquifers that dot the U.S. are used for such things as drinking water, lawn care, and hygiene. Also water is used as a power source for large portions of the country, the most common form of power through water is dams. Dams force the water to travel down very specific passage ways until they hit turbines which begin to spin, using the motion of the turbines, generators are charged which send power to varying station throughout the area. Also area’s with still water known as bog’s which help control animal population. Occult precipitation helps when not enough rain has fallen. Bogs are know to be carriers of various diseases and parasites that help to control population.

Destruction Water is one of the most powerful forces in the world, as well as one of the most destructive. Floods, tsunamis, and flash floods are some of the most well known destructive forms of water, but one that is not very well known is a Rouge wave. These random unpredictable waves cause massive amounts of damage to ships at sea. Scientists have studied these waves and concluded that rouge waves absorb the waves around them and turn into gigantic 150 foot waves. Tsunamis are similar in form to rouge waves but are different in how in they form and their size. The largest recorded wave was 1722 feet tall.

Occult precipitation- precipitation that is not registered by a standard rain gauge because it arrives as mist, condensing on surfaces, including vegetation canopies. Bog- a wet land ecosystem in which the water supply is entirely from rainfall.
