• along the coast of a continent
• anywhere

• landslides
• ocean currents
• shaking that occurs in Earth's inner core
• movement of melted rock in the mantle

What is a fault?

• a place on Earth where earthquakes cannot occur

• an earthquake

In which of these ways can volcanoes help build up new land?

• by adding gases to the atmosphere
• by adding lava to Earth's surface
• by adding water vapor to the atmosphere

An earthquake is - 

• crust through which lava escapes
• a sudden movement in the Earth's crust
• a kind of chemical weathering that changes the Earth
• a huge wave that washes over the Earth

Why can't we feel the movement of Earth's plates?
