Weather, Erosion and Deposition
After reading students' responses, click on their names to view their animations.
Rafaela: First, a storm starts and wind starts to blow which causes weathering. Then, ocean currents form that start to push the rock into the cliff which causes erosion. Finally, the rock forms sand at the bottom which is deposition.
Sophia: First, little rain drops freeze on the rock and weather the rock. Then, gravity pulls it down and rock starts to erode to the bottom of the ocean. Finally, layers of sand form at the bottom of the ocean and deposit.
Jack: First, the rock is weathered. An example of weathering is lightning that strikes its target breaking it apart and then turns into sediment. Then, by either gravity or weather, the sediment gets into or near a water source and gets eroded (picked up) by the water. Finally, the sediment gets deposited (dropped off) and sits still for a few decades.
Hannah: First, the rain falls into the cracks and weathers the rock into smaller and smaller pieces. Then, wind erodes the small rocks slowly into the ocean. Finally, the rocks deposit into the bottom of the ocean to form sand.
Beckett: First, a storm cloud gets blown above the cliff by the wind. A lightning bolt cracks the cliff and weathers the rocks. Then, gravity makes boulders around the cliff erode into the ocean. Finally, the rocks fall into the ocean and deposit into layers of sand.
Caleb: First, when the rain comes crashing down on the rock, the water gets in the cracks and weathers the rocks into smaller pieces. Then, the rocks fall in the ocean and by erosion. Finally, the rocks form a pile down beneath the water in the ocean and deposit.
Nora: First, the wind blows really hard and weathers the cliff. Then, the rocks weather into smaller rocks and gravity pulls the rocks off the cliff. Finally, the rocks that eroded off the cliff forms a mountain at the bottom of the sea. That is a demonstration of deposition.
Nicolly: First, weathering blew small rocks together and they became small. Then, erosion made gravity bring the small rocks in the water. Finally, deposition made layers of sand form at the bottom of the ocean.
Lyla: First, the wind knocks the two rocks next to each other soon to make it weather. Then, the two rocks get pushed closer and they erode into the ocean. Finally, the two rocks are minuscule pieces of rock. The deposition makes it so there are layers of sand at the bottom of the ocean.
Amanda: First, sea blue waves crash into the gray rocks weathering them into smaller pieces. Then, the same waves grab the small rocks pushing them down to the ocean, eroding them. Finally, the small rocks deposit in the bottom of the sea, forming lots of layers as this happens over and over again.
Carolina: First, wind blows, choppy waves form and the waves weather down the rock. Then, when the waves flow they erode the rock by carrying the weathered pieces to the sea. Finally, the rock deposits at the bottom of the sea to make sand.
Milo: First, a lightning bolt disintegrated a boulder and weathers it into very small rocks. Then, wind blows away the rocks and erodes the rocks. Finally, sand deposits at the bottom of the ocean in layers.
Wyatt W.: First, the clouds go dark. Then the thunder happened and a tornado hit. It shot sand everywhere and weathered the rock. Then, thunder hit. The boulders started eroding. It was totally a disaster. Splashes everywhere. Finally, the storm stopped and the sand deposited back into the ocean and hit the bottom.
Jacoby: First, A hurricane blows rock against other rocks and weathers them. Then, wind blows the sand around eroding it to the bottom of the ocean. Finally, layers of sand deposit at the bottom of the ocean.
