Plate Tectonics
Physics ⇒ Earth and Space Physics
Plate Tectonics starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plate Tectonics.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 8
Describe how mountain ranges are formed by plate tectonics.
Describe the role of convection currents in the mantle in plate movement.
Describe what happens at a convergent plate boundary.
Describe what happens at a transform plate boundary.
Explain how plate tectonics can cause volcanic eruptions.
Explain how the age of rocks on the ocean floor supports the theory of plate tectonics.
Explain why earthquakes are common along plate boundaries.
Explain why volcanoes are often found near convergent and divergent boundaries.
At a transform boundary, plates move (1) Toward each other (2) Away from each other (3) Past each other horizontally (4) Over each other
