Chapter 6 Lesson 3 Plate Tectonics

The theory of plate tectonics __________________.

• states that Earth's surface is made of rigid slabs of rocks or plates that move with respect to each other.

• states that all of the continents used to be one supercontinent

• states that continents are in constant motion

The lithosphere is ________________-.

• a layer of crust

• a layer of mantle

• a layer of crust and solid upper-most mantle

• a plastic layer of rock in the mantle

The asthenosphere is _________________.

• a layer of crust

• a layer of mantle

• a layer of crust and solid upper-most mantle

• a plastic layer of rock in the mantle

Ridge push is the result of

• a convergence at a plate boundary

• rising magma at a plate boundary

• plates sliding past each other at a plate boundary

• subduction of a denser plate

Tectonic plates are ________________-

• a plastic layer of rock in the mantle

• slabs of crust and upper mantle

• slabs of continental crust

• slabs of oceanic crust

At the transform boundary, _____________.

• plates move away from each other

• one plates subducts under another

• plates move toward each other

• plates slide past each other

__________________ causes tectonic plates to move.

• earthquakes in the crust

• magnetism on the seafloor

• rotation of the Earth

• convection currents in the mantle

In a divergent plate boundary, _________________.

• two plates seperate

• two continental plates collide

• two plates slide past one another

• an oceanic plate and a continental plate collide

Earthquakes happen ________________.

• when plates collide

• when plates slide past one another

• when plates move across from one another

• when an oceanic and continental plate collide
