What is a Landslide?
Sediments/Boulders/Rock/Soil that goes downhill fast
What is an Avalanche?
Snow + Soil/Rock that goes downhill fast
What is a Mudslide?
Mud + Soil/Rock that goes downhill fast
What is a Creep?
Soil/Rock that goes downhill SLOW
What is a Beach Sand Dune?
Pile of Sand at the back of a beach
What is a Beach
Space between dunes and water
What is Desert Pavement
Pebbles and gravel left behind after sand silt and clay is blown away
What is a Desert Sand Dune?
Pile of sand in desert
What is a Moraine?
Piles of sediments left behind along the sides and ends of a glacier
What is a Erratic
Non-native rock left behind by a glacier
What is a Drift
Anything carried by the glacier
What is a U-Shaped Valley
Valley between mountains in the shape of a U
What is a Sand Bar
A extension of sand across an opening
What is a Delta
Fan-Shaped pile of sediment at the mouth of a river emptying into the ocean
What is a Meander
A curve in a river that gets more curvier because faster moving water on the outside of the curve erodes the outside edge and the slow moving water deposits sediments in the inside edge
What is a Flood Plain
Area covered by a river when it floods, extremly fertile
What is a Levee
Piles of sediement along the sides of a river because the water drops sediment when it floods
What is a Waterfall
Forms where flowing water undercuts softer rock that is below harder rock
What is a Canyon
Steepsided water cut by fast rivers
What is a V-Shaped Valley?
Steep-sided valley formed by rivers eroding downward(Rivers only touch the bottom of the valley)
List the sediments in size order from biggest to smallest
Boulder,cobble,pebble,sand,silt,clay
What 2 things does a delta need in order to form?
Sediment-enriched flow of water and calm ocean the water pours into
List any 3 erosion land form that is depositing/Constructive.
Beach Sand Dune, Moraines, Erratic, Drift,Sand Bar, Delta, Floodplain, Levee
List any 3 erosion land form that is removing sediment/destructive.
Landsilde, Avalanche, Creep, Mudslide, Desert “Pavement”, U-shaped valley, waterfall, canyon, V-shaped valley
