<p> Landform Formation</p><p>Landform How Did It Form? Definition (weathering, erosion, *draw it deposition; from wind, water, here or ice?) mountain a landform caused by the uplift of the Earth’s crust; Tectonic plates push against each created when two crustal other & raise land plates press against each Or volcanoes forming layers other</p><p> volcano an opening in the Earth’s crust through which lava, Lava cools & hardens ash, and gases flow Or plates collide & push up land</p><p>Sand Dune a mound, hill, or ridge of wind-blown sand</p><p>Sand piles up (deposits) Landform Formation</p><p>Landform How Did It Form? Definition (weathering, erosion, *draw it deposition; from wind, water, here or ice?) beach gently sloping shore next to a body of water, Water weather, erode/move, & washed by waves or tides, deposit sediments. Water can break down (weather) or build up often covered by sand and pebbles</p><p>Glacier a large river of ice that moves Ice, snow builds up/deposits – lots of LAYERS</p><p>Glacial valley Glacier/ice cutting the mountain A steep-sided, U-shaped (weathering) & carries/erodes sediments away valley formed by the erosional forces of a moving glacier.</p><p> terminal An accumulation of Dropping off/depositing sediments moraine from glacier boulders, stones, or other debris carried and deposited by a glacier.</p><p>Landform How Did It Form? Definition (weathering, erosion, *draw it here deposition; from wind, water, or ice?) valley a low area between v-valley: carved/weathered by water hills and mountains; V- shaped valleys are u-valley: carved/weathered by glaciers formed by rivers; U-shaped valleys are formed by glaciers</p><p>Floodplain the land that gets Water deposited covered by water from a stream or river during a flood</p><p> plain a nearly level area Water & wind that has been eroded weathering/eroding away or where material has sediments or depositing sediments been deposited Landform How Did It Form? Definition (weathering, erosion, *draw it deposition; from wind, water, here or ice?) plateau a nearly level area that has been uplifted</p><p>Wind & water weathering & eroding sediments away</p><p> delta a fan-shaped deposit at the mouth of a river Sediments DEPOSITED by a river</p><p> canyon a long, narrow, deep valley River weathers/breaks rock & with steep walls that is erodes sediments away formed by running water cutting into the earth Landform How Did It Form? Definition (weathering, erosion, *draw it here deposition; from wind, water, or ice?) meander a curve or loop in a river Water going around rocks, boulders, trees</p><p> cave A hollow or natural Water carves/weathers cave passage under or into the earth, especially one with an opening to the surface</p><p>Water dripping through cracks StalaCtites– hanging from the Ceiling StalaGmites – rising from the Ground sinkhole a hollow place or Water weathers soil away & makes ground very moist/weak depression in which drainage collects </p><p>Landform How Did It Form? Definition (weathering, erosion, *draw it here deposition; from wind, water, or ice?) island Water deposits sediments/sand A land mass, especially Or Volcano’s layers one smaller than a continent, entirely surrounded by water</p><p> arch A structure that spans Desert arch – wind weathers/breaks rock over an open area and gives support Oceanic arch – water & wind weathers/breaks rocks</p><p>Groundcover Small plants that grow Water deposited & plants help on the forest floor or in stop erosion of water a field (mosses, ferns, and grasses)</p><p>Weathering Causes: wind, water, ice, plants, The process of breaking gravity, acid rain rock into soil, sand, and other tiny pieces</p><p>Erosion Causes: wind, water, ice/glaciers, The process of moving gravity sediments from one place to another</p><p>Deposition Causes: wind, water, glaciers, The process of dropping gravity (depositing) sediment in a new location Constructive Volcanoes, earthquakes, water, Actions that build up or wind, gravity, ice Forces construct landforms</p><p>Destructive Volcanoes, earthquakes, water, Actions that wear down wind, gravity, ice Forces or destroy landforms</p>
