look it up yourselves! Don't be lazy and look up the answers. That's why teachers give books :)
Nine piles of sand.
Sand spits are narrow coastal landforms made up of sand that extend from the shoreline into open water, often forming at the mouths of bays or harbors. Barrier islands are long, narrow islands that run parallel to the mainland coast, typically composed of sand and formed by marine processes such as wave action and longshore drift. Both sand spits and barrier islands provide protection to the mainland by acting as natural barriers against coastal erosion and storm surges.
The massive wind blown piles of sand are called sand dunes. This is when sands blow into a pile.
No. Sand is a category of sediment. You can, however, have landforms that are made of sand such as barrier islands and sand dunes.
weathering
Barrier islands are created as a result of sediment deposition and accumulation along coasts, forming a protective barrier between the ocean and the mainland. They are shaped and reshaped by wave and tidal action, with sand dunes forming the islands' characteristic features. Over time, barrier islands can migrate and change shape due to natural processes like storms and sea level rise.
Sand dunes: mounds of sand shaped by wind or water. Sandbars: underwater structures made of sand that can be found near coastlines or in rivers. Sandspits: narrow landforms made of sand extending into bodies of water. Sandy beaches: shorelines made of sand that are typically found along coastlines.
Barrier islands form a narrow strip of land parallel to the coast and separated from the mainland by a lagoon or bay. They serve as a protective barrier against ocean waves, storms, and erosion for the mainland.
They can use sand bags to slow down the rate of erosion on barrier islands.
Accumulating sand in areas of erosion helps to maintain the size and stability of barrier islands, acting as a natural defense against ocean waves and storms. However, removing sand disrupts the natural balance and can lead to the shifting of barrier islands, as they rely on a delicate equilibrium of sediment transport to remain in place. Sustainable management practices that prioritize sand accumulation and minimize removal are crucial for preserving barrier island ecosystems.
No, they are really large sand banks, like most of the barrier islands up the east coast of the US.
Huge piles of sand are called sand dunes. Sand dunes typically form in deserts or coastal areas where there are strong winds that shape and move the sand into these large structures.
