Inside Earth

The Earth's inner core is 

• a layer of hot rock
• a dense ball of solid metal
• a layer of molten metal
• part of Earth's outer skin

Most geologists think that the movement of Earth's plates is caused by 

• Earth's magnetic field
• conduction
• earthquakes
• convection currents in the mantle

The Earth's mantle is

• a layer of molten metal

What is the correct order of Earth's layers? Starting from surface

• Crust, mantle, outer core, inner core
• outer core, inner core, crust, mantle
• crust, outer core, inner core, mantle
• mantle, outer core, inner core, crust

Most geologists rejected Wegener's idea of continental drift because Wegener

• scared them with his ideas
• used different types of evidence to support his theory
• was interested in Earth millions of years ago
• could not identify a force that could move the continents
