A mathematical equation stating that a volume of water, passing through a specified area of material at a given time, depends on the material's permeability and hydraulic gradient. Floats can be weighted to be neutrally buoyant at a particular depth, where they drift in the current while emitting periodic sounds. Almost microscopic algae and animals that are carried by current and waves. Dams' affects: More precise sampling may be accomplished using a submersible with robotic arms or a remotely operated vehicle equipped with television so that the area where the rock was found can be described in detail. Ocean water freezes at a lower temperature than freshwater. A collaborative effort of scientists from several oceanographic institutions aims to provide accurate measurements at this interface particularly for the World Ocean Circulation Experiment (WOCE). Relationships between plants and animals of a biome having to do with what they eat. This change in the suns position from winter to summer means that more energy's reaching the ocean and therefore warms the water. a dome-shaped mound consisting of a layer of soil over a large core of ice, occurring in areas with high amounts of permafrost. Some rocks are fractured in a rectangular fashion and streams develop on the fractures. The information below should not be interpreted as an extension of the rules.

Points are awarded for quality and accuracy of answers. surface winds drive surface currents, and each layer of water drags the layer below, but the Coriolis Force changes each layer's direction slightly to make a spiral effect. slows the movement of water and increases evaporation from reservoirs; may hold water back, store water, control flooding, and generate electricity. A device that determines the distance of an object under water by recording echoes of sound waves. Sediment sampling devices include a box corer that drops into the mud and brings back a block of near-surface sediment. brightening of the night sky caused by street lights and other man-made sources, which has a disruptive effect on natural cycles and inhibits the observation of stars and planets. Eddies can form. der Tiergarten. Occur where a river meets an area of rock that erodes slowly, process by which a stream in one watershed is captured by a stream in an adjacent watershed, channel irregularities such as rapids and waterfalls, deposits of sand and soil at the mouth of a river form, graph used to show if sediments will deposit, transport, or erode sediment. Suppose a meteor having a mass of 7.0 kg passes within 3.0 m of the surface of the satellite. direction of water flow is where two rivers come together. Is related to changes in temperature of a gas or object without changes in phases. These channels tend to form in rivers that have a significant amount of sedimentary load. +change in x over change in y but in topo map terms, The lowest level to which a stream can erode or running water can flow (the part of the slide where a kid starts to slow down - the flattened bottom), the flat, wide area of land along a river; an area that is subject to natural flooding from an adjoining waterway, cut bank, point bar, oxbow lake, natural levee, & backswamp (see images). The boundary where the ocean and the land meet; temporary and unstable, The evolution of bogs and marshes from interactions between surface and groundwater, Wetlands are formed from these interactions and are present in climates and landscapes that cause ground water to discharge to land surface or that prevent rapid drainage of water from the land surface.
