100 Why do people spend millions of dollars on beach reclamation? If we didn’t spend money on beach reclamation, the beaches would all erode and we wouldn’t have beaches. Main

200 Why do people dredge sand from a channel? Channels are dredged so boats can pass through. Main

300 What happens to the sand that is dredged from the channels? The sand is used to replace sand that has been eroded from the beaches. Main

400 What is deposition and how does it change the Earth? Deposition is the process by which sediment drops out of the water and adds to the landform, creating a delta. Main

500 How does weathering change the Earth’s surface? Weathering changes the Earth’s surface by braking down rocks on the Earth’s surface. Main

100 Is weathering a slow or quick process? Weathering is a slow process. Main

200 How does a volcano help build up new land? A volcano helps build up new land when the lava cools, creating a new land. Main

300 How does a glacier help create new soil? A glacier helps create new soil because they carry soil and drop it at the bottom of the glacier. Main

400 The movement of two continents can be explained by the movement of the plates, called ______________. Plate Tectonics Main

500 What is the difference between lava and magma. Lava is hot molten rock that flows onto Earth’s surface and magma is melted rock that flows underneath Earth’s surface. Main

100 What tools to Seismologists use to monitor the Earth’s crust? Seismographs are used to help record the Earth’s surface for movement. It also helps locate the epicenter. Main

200 What is an epicenter? The epicenter is a spot above the fault where Earthquakes start. Main

300 What are the two methods of controlling flooding and how do they stop flooding? Levees: walls of Earth and keep water from coming onto land Dams: hold back the flow of water Main

400 How does erosion and deposition of sand cause problems for humans? Erosion and deposition remove sand from one beach and builds up another. Sand may also fill the channel, causing the water to become too shallow for ships to pass. Main

500 What is a jetty and how does it help restore beaches? A jetty is a man-made wall that is used to help protect the beaches from erosion. Main

100 What is a destructive force? A destructive force is a force that builds up the Earth’s surface and includes weathering, erosion, impact of organisms and earthquakes. Main

200 What is a constructive force? A constructive force is a force that builds up the Earth’s surface and includes deposition, earthquakes and faults. Main

300 Constructive, Destructive or Both…why? Earthquake Both because it can knock things down and form mountains and lakes. Main

400 Constructive, Destructive or Both…why? Weathering Destructive-Weathering tears down the Earth’s surface Main

500 Constructive, Destructive or Both…why? Volcanoes Both, because volcanoes’ magma can destroy towns, but they are constructive because magma builds up, creating new land. Main

100 Constructive, Destructive or Both…why? Glaciers Both because glaciers can destroy everything in its path, but can also build up new landforms. Main

200 Constructive, Destructive or Both…why? Tsunami Destructive because a tsunami destroys everything in its path. Main

300 Constructive, Destructive or Both…why? Erosion Destructive-tearing down of Earth’s surface main

400 Constructive, Destructive or Both…why? Impact of organisms AND landslides Destructive because it’s tearing down or destroying Earth’s surfaces. Main

500 Constructive, Destructive or Both…why? Faults AND Deposition Constructive because faults form mountains and depostion adds soil or sand to an existing landform. Main
