How can a levee help prevent flooding?

• It keeps rising water inside stream channels
• It acts as a drain when water gets too high
• It pulls water downstream before it can flood
• It forms a lake with excess flooding

• by holding soil in place with their roots

How does a hot spot form a chain of volcanoes?

• A hot spot allows magma to explode froma vent
• The hot spot allows magma to ooze from a vent
• Volcanoes form above a hot spot.  The volcanoes move as the plate moves
• The hot spot creates alternating layers of lava and as
