Layers of the Earth and Energy

Front

The Ring of Fire generally has these landforms in common: deep sea trenches, rift valleys, tornadoes; volcanoes, thunderstorms, earthquakes; rift valleys, whirlpools, tsunamis; volcanoes, rift valleys, deep sea trenches.

Back

volcanoes, rift valleys, deep sea trenches

Front

When hotter material rises and cooler material sinks, this process is called:
- trenches
- convection
- boundary
- tectonic plates

Back

convection

Front

What is layer A representing? Options: continental crust, oceanic crust, trenches, mantle, convection currents

Back

oceanic crust

Front

What is the main driving force of plate tectonic energy?

Back

mantle

Front

What process is layer B representing? Options: crust, continental crust, oceanic crust, convection currents, mantle

Back

convection currents

Front

The process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge is called sea-floor spreading.

The theory that continents are slowly moving over Earth's surface is called

Back

the theory of continental drift

Front

Divergent plates underneath the ocean have caused the mid-ocean ridge to form.
