• crust
• lithosphere

What is the outermost solid layer of Earth called?

• mantle
• crust
• inner core

The __________ is a layer of weak or soft mantle that is made of rock that flows slowly. Tectonic plates move on top of this layer.

• crust
• inner core
• asthenosphere

• Divergent Boundary (divide)

• Transform Boundary (slide)

• Plate Boundary

Mountains are created when....

• An Oceanic plate subducts under a Continental Plate
• Two continental plates pull apart

Temperature _____________________ as you go deeper into the earth.

• increases
• decreases
• goes up and down depending on the layer
• stays the same

Subduction occurs when one plate slides beneath another plate. The figure below shows the process of subduction. Notice that the oceanic plate slides beneath the continental plate.

What happens when the crustal plates move as shown in the figure?

• An ocean forms.

• Volcanic mountain ranges form.

• Sea-floor spreading occurs as the oceanic plate moves.

• A transform boundary forms where the subduction occurs.

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

Earth's plates are...

• constantly moving and changing the earth

• Never moves
• Moves seldom and very fast
• Moves when it feels like it
