Landform Formation

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

volcano an opening in the Earth’s crust through which lava, Lava cools & hardens ash, and gases flow Or plates collide & push up land

Sand Dune a mound, hill, or ridge of wind-blown sand

Sand piles up (deposits) Landform Formation

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

Glacier a large river of ice that moves Ice, snow builds up/deposits – lots of LAYERS

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.

terminal An accumulation of Dropping off/depositing sediments moraine from glacier boulders, stones, or other debris carried and deposited by a glacier.

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

Floodplain the land that gets Water deposited covered by water from a stream or river during a flood

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

Wind & water weathering & eroding sediments away

delta a fan-shaped deposit at the mouth of a river Sediments DEPOSITED by a river

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

cave A hollow or natural Water carves/weathers cave passage under or into the earth, especially one with an opening to the surface

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

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

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

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)

Weathering Causes: wind, water, ice, plants, The process of breaking gravity, acid rain rock into soil, sand, and other tiny pieces

Erosion Causes: wind, water, ice/glaciers, The process of moving gravity sediments from one place to another

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

Destructive Volcanoes, earthquakes, water, Actions that wear down wind, gravity, ice Forces or destroy landforms
