What is the correct order (starting from the surface) of Earth's layers?

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

The part of the Earth system that contains all of Earth's water is called the 

• atmosphere
• geosphere

Particles of hot soup rise slowly in a pot simmering on a stove . As the hot soup nears the surface it begins to cool. The cooler soup sinks, forming a constant movement of the soup in the pot is called a(n)

• magnetic field 
• energy system
• convection current
• conduction loop

Which part of Earth contains most of it's mass?

• the biosphere
• the geosphere

• the hydrosphere

In which layer of Earth is the asthenosphere located?

• inner core 
• outer core
• mantle 
• crust

What do geologists call the crust and upper mantle?

• listhosphere
• asthenosphere
• mesophere
• outer core

Why is the inner core made of solid metal?

• Because it is so hot it turns from liquid to solid
• Because of the weight of the crust
• Because of it's temperature
• Because of the pressure of the other layers beating down on it
