  1. What causes a volcano to erupt? A volcano erupts when magma escapes from inside the earth. As the magma is escaping from a confined space, a lot of energy is released with it, as happens with any other explosion.

  2. The effects of volcanoes. It can cause houses to burn down. Make buildings to collapse.

  3. What causes landslides? Some slopes are susceptible to landslides whereas others are more stable. Many factors contribute to the instability of slopes, but the main controlling factors are the nature of the underlying bedrock and soil, the configuration of the slope, the geometry of the slope, and ground-water conditions.

  4. The effects of landslides. Landslides can tear down cities. Leave mud everywhere.

  5. What causes an earthquake? Movement of the earth's crusts along the plate margins otherwise known as plate tectonics causes up heaving & instability in land/ocean masses. Plate Tectonics is the movement of the earths crust. The earths plates are constantly moving and push together and often they get into a "traffic jam". As plates move in different directions, pressure builds up over time. When the pressure overcomes the tendency of the plates to press together, there is a sudden shift resulting in an earthquake.

  6. The effects of an earthquake. When an earthquake hits Buildings collapse , people are homeless, and people are hurt.
