According to Wegener's hypothesis of continental drift

• Earth's surface is made up of seven major landmasses.
• the continents do not move.
• Earth is slowly cooling and shrinking.
• the continents were once joined together in a single landmass.

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 soup that moves energy toward the surface of the pot. This constant movement of the soup in the pot is called a(n)

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

Any trace of an ancient organism that has been preserved in rock is called a

• landform
• continent
• fossil
• landmass

The transfer of energy through empty space is called

• conduction
• convection
• radiation
• subduction

In sea-floor spreading, molten material rises from the mantle and erupts

• along the edges of all the continents
• along mid-ocean ridges
• in deep-ocean trenches
• at the north and south poles

Old oceanic crust is more dense than new oceanic crust because it is

• hot
• moving toward a deep-ocean trench
• cool
• closer to the mid-ocean ridge

In which location would you most likely find volcanoes?

• far from plate boundaries
• along transform boundaries
• where two continental plates collide
• along mid-ocean ridges and where a plate is subducted

The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion is the theory of

• subduction
• plate tectonics
• deep-ocean trenches
• sea-floor spreading

A place where two plates slip past each other, moving in opposite directions, is known as a

• transform boundary
• divergent boundary
• convergent boundary
• rift valley

A collision between two pieces of continental crust at a converging boundary produces a

• mid-ocean ridge
• deep-ocean trench
• rift valley
• mountain range
