• Outer Core

• Crust

Mountains form ....

• at convergent boundaries where two plates meet head on.

• at divergent boundaries where two plates move away from each other.

• at transform boundaries where two plates slide past each other.

• where igneous rocks pile up after volcanic eruptions.

Which layer of the earth is known for being the thinnest and having the lowest density?

• Mantle

• Outer Core

• Crust

• Inner Core

Which of the following best explains how volcanoes form on Earth?

• Volcanoes form from transform boundaries where plates slide past each other.

• All mountains are potential volcanoes if an opening forms at the top.

• At divergent boundaries where plates pull apart from each other allowing magma to rise to the surface.

• At subduction zones where tectonic plates are pushed/pulled by the convection currents in the mantle.

What type of heat transfer occurs in the mantle of the Earth that is responsible for pulling/pushing tectonic plates like a conveyor belt?

• convection

• conduction

• radiation

• subduction

At which plate boundary would new oceanic crust form?

• New (young) oceanic crust never forms.

• convergent; plates push into each other creating a new seafloor

• divergent; magma rises and cools to form a new seafloor

• transform; plates slide past each other forming a new seafloor
