Sand dunes, Canyons and Deltas 5th grade Science
What is a delta? an area at the end of a river where sediments are deposited and build up
How are deltas formed? Weathering Erosion Deposition
How are deltas formed? When a river reaches a lake or sea, the water slows down The sediments are then dropped at the *mouth of the river. When ocean waves cannot carry the sediments out to the ocean, a delta is formed.
Where can you find a delta? At the mouth of a river The mouth of a river is where a river meets the ocean.
What shape is this delta?
How is a delta formed? Deposition by water
What is a Sand dune A hill of sand piled up by the wind
How is a sand dune formed? Weathering Erosion Deposition
How is a sand dune formed? Dunes may form wherever there is a lot of loose sand and enough wind to move it.
Where can you find a sand dune? Beaches and deserts are common places for dunes.
Which way was the wind blowing from?
How are sand dunes formed? Wind Erosion and deposition
