What is an estuary?

• A long piece of iron inserted through the walls of a building

• A flexible pad made from rubber and lead

• A tidal mouth of a large river

What is the purpose of a levee?

• To absorb the impact of an earthquake

• To prevent the overflow of a river

• To repair a building

• To strengthen a building

What is a storm surge?

• A violently rotating column of air touching the ground

• A sudden shaking of the earth's crust

• A rising of the sea as a result of atmospheric pressure changes and wind associated with a storm

• A storm with a violent wind

What are stilts used for?

• To repair a building

• To support a structure that might otherwise be damaged by water

• To prevent flooding

• To absorb the impact of an earthquake

What is the function of a seawall?

• To absorb the impact of an earthquake

• To prevent the overflow of a river

• To protect the shore from waves and erosion

What is a tornado?

• A violently rotating column of air touching the ground

• A sudden shaking of the earth's crust

• A rising of the sea as a result of atmospheric pressure changes and wind associated with a storm

• A storm with a violent wind

• What is a shear wall?

• • a structural support element that promotes forces like heavy wind or seismic activity

• • a structural support element that resists forces like heavy wind or seismic activity

• • a structural support element that resists forces like destruction caused by humans

• • a flexible element that allows wind and rain to flow freely in a certain environment
