When two tectonic plates slide past each other, neither crashing together, nor pulling apart, the boundary between them is called...

When an oceanic plate is subducted under a continental plate, a deep valley is formed in the ocean. What is this valley called? 

• a trench
• a rift zone
• ocean spreading ridge
• Continental crust

When a continental plate is pulled away from another continental plate, the area of crust that is thinned and pulled apart is called. 

• a trench
• a rift zone or rift valley
• ocean spreading ridge
• Continental crust

When an oceanic plate is pulled away from another oceanic plate,, magma spews from below the crust and this is formed. 

• a trench
• a rift zone or rift valley
• ocean spreading ridge
• continental crust

When convergent plates collide, if both plates are pushed upward, this forms.  

• Fissures
• Mountain Ranges
• Volcanoes
• Rock Cycle
