    • Ocean water is the salt water that covers most of the Earth's surface. 
    • Brine is a type of saltwater that is found in lakes, ponds, and other bodies of water that are isolated from the ocean, in some special cases we can see a brine pool. A water so dense with salt that it won't mix with seawater and forms a clearly defined “lake” on the ocean floor, becoming a toxic environment where few organisms survive

    Unsaturated zone: portion of the subsurface above the groundwater table.

    Water table: the upper level of the saturated zone of groundwater

    Saturated zone:     the area below the water table that holds water.

    Aquifer: a body of rock or sediment that stores groundwater and allows the flow of groundwater.

    • The soil and rock in the unsaturated zone contains air as well as water in its pores. 
    • In some places this zone is absent (lakes and marshes). 
    • In some places it is hundreds of meters thick (arid regions).
    • Not a source of readily available water for human consumption.  
    • Provides water and nutrients that are vital to the biosphere.
    • Used for the cultivation of plants, construction of buildings, and disposal of waste.

    • All of the pores, cracks, and spaces between rock particles are completely filled with water.
    • Also known as the phreatic zone after the Greek word for “well” or “spring”.
    • The top of the saturated zone is known as the water table.
    • Water pressure and atmospheric pressure are equal at the water table.
    • In an aquifer, there is enough groundwater that it can be pumped to the surface and used for drinking water, irrigation, industry, or other uses.

When the aquifer is full, and the water table meets the surface of the ground, water stored in the aquifer can appear at the land surface as a spring or seep. Recharge areas are where aquifers take in water; discharge areas are where groundwater flows to the land surface. Water moves from higher-elevation areas of recharge to lower-elevation areas of discharge through the saturated zone. ]]> 2023-08-29 04:17:53 UTC https://padlet.com/lizacedeno1/r8x071lj7ckfx2am/wish/2676112726 lizacedeno1 https://padlet.com/lizacedeno1/r8x071lj7ckfx2am/wish/2676117038 54% of groundwater is saline and exists mostly below oceans.

Precipitation and water runoff feed bodies of surface water. Evaporation and seepage of water into the ground, on the other hand, cause water bodies to lose water. Water that seeps deep into the ground is called groundwater.]]> 2023-08-29 04:34:56 UTC https://padlet.com/lizacedeno1/r8x071lj7ckfx2am/wish/2676130544 Types of Surface Water lizacedeno1 https://padlet.com/lizacedeno1/r8x071lj7ckfx2am/wish/2676135094 There are three types of surface water perennial, ephemeral, and man-made. 

    1. Perennial, or permanent: surface water persists throughout the year and is replenished with groundwater when there is little precipitation. 
    2. Ephemeral, or semi-permanent: surface water exists for only part of the year. Ephemeral surface water includes small creeks, lagoons, and water holes. 
    3. Man-made surface water: is found in artificial structures, such as dams and constructed wetlands.

How fast water soaks into, or infiltrates the soil depends on soil type, land use, and the intensity and length of the storm. Water infiltrates faster into soils that are mostly sand than into those that are mostly clay or silt. 
    Rain that cannot be absorbed into the ground collects on the surface, forming runoff streams.

Water then moves through the saturated zone to groundwater discharge areas. 

    Evaporation occurs when water from such surfaces as oceans, rivers, and ice is converted to vapor. Evaporation, together with transpiration from plants, rises above the Earth’s surface, condenses, and forms clouds. Water from both runoff and from groundwater discharge moves toward streams and rivers and may eventually reach the ocean. Oceans are the largest surface water bodies that contribute to evaporation. ]]>     2023-08-29 04:44:02 UTC https://padlet.com/lizacedeno1/r8x071lj7ckfx2am/wish/2676139743     lizacedeno1 https://padlet.com/lizacedeno1/r8x071lj7ckfx2am/wish/2676140355 2023-08-29 04:44:40 UTC https://padlet.com/lizacedeno1/r8x071lj7ckfx2am/wish/2676140355 How much we depend on surface water? lizacedeno1 https://padlet.com/lizacedeno1/r8x071lj7ckfx2am/wish/2676144056

    • The accumulation of trash, oil, fertilizers and animal waste affects water quality. 
    • Inflow of sediment can cloud water, blocking sunlight from reaching aquatic plants. 
    • Sediment also settles to the bottom of streams, clogging the gravel beds used by fish for laying their eggs. 
    • Nutrients, such as phosphorus and nitrogen from fertilizers enter the water and promote unusually rapid algae growth. As this algae dies, its decomposition reduces or eliminates oxygen needed for survival by fish and crabs and other aquatic life.
