Which of the following is NOT evidence supporting Alfred Wegner's continental drift ideas?

• earthquakes are frequent along transform boundaries
• continents fit together like puzzle pieces
• similar fossils are found on distant continents
• similar rocks and mountains are found on distant continents

Which physical layer of Earth is right below the lithosphere and is soft or like warm playdough?

• asthenosphere
• crust
• mantle
• mesosphere

Why didn't scientists believe Wegener right away when he proposed his idea for continental drift?

• He didn't have enough evidence and could not explain how or why the continents could actually move.
• He couldn't explain why the oceanic crust is so dense
• Climate patterns on Pangaea didn't make sense to them
• He couldn't find fossils on far away continents

Which scientist studied seismic waves from earthquakes, to discover Earth's inner core is solid?

• Inge Lehmann
• Alfred Wegener
• Marie Tharp
• Brittany Williams

Which compositional layer of Earth is made of iron and nickel?

• core
• mantle
• crust
• mesosphere

Which compositional layer is about 1% of Earths mass?

• crust
• mantle
• lithosphere
• core

Which physical (mechanical) layer has convection currents that cause the tectonic plates to slide around?

• asthenosphere
• mantle
• lithosphere
• outer core
