3.5.1 Tectonic Processes and Landforms

• At a convergent boundary, plates move towards each other.
• Mountain ranges are commonly formed at convergent boundaries.
• Deep ocean trenches are formed at transform boundaries.

  False
• Transform boundaries typically result in volcanic eruptions.

  False
• Fault lines are characteristic landforms of transform boundaries.
• At transform boundaries, plates slide past each other horizontally, resulting in earthquakes but little volcanic activity
• Plate tectonics shapes the Earth's surface through processes at different plate boundaries
• The processes at plate boundaries drive geological phenomena such as earthquakes, volcanoes, and mountain building.


  True
• Match the boundary type with its key processes and associated landforms:

  Convergent ↔️ Subduction, mountain ranges

  Divergent ↔️ Seafloor spreading, mid-ocean ridges

  Transform ↔️ Earthquakes, fault lines
• At divergent boundaries, plates move apart, causing seafloor spreading and the formation of rift valleys
• What is the formation process of mountain ranges at convergent boundaries?

  Collision and uplift
• What geological feature is formed by the subduction of a denser oceanic plate under a less dense plate?

  Deep ocean trench
• What type of plate boundary is associated with fault lines?

  Transform
• What is the primary cause of tsunamis at subduction zones?

  Earthquakes near subduction zones
• The theory that the Earth's surface is composed of moving plates is called tectonics
• Volcanoes are only found at convergent boundaries.

  False
• Earthquakes are the primary geological process at transform boundaries.


  True
• Seafloor spreading occurs at divergent boundaries.
• Match the boundary type with its key processes and landforms:

  Convergent ↔️ Subduction, mountains, trenches

  Divergent ↔️ Seafloor spreading, rift valleys

  Transform ↔️ Earthquakes, fault lines
• At convergent boundaries, the denser plate is pushed under the less dense plate, causing subduction, mountain building, and volcanic activity
• Key geological processes associated with plate movement at convergent boundaries

  1️⃣ Subduction

  2️⃣ Mountain building

  3️⃣ Volcanic activity
• Mountain ranges are formed at convergent boundaries through the collision of continental plates.


  True
• Order the definitions of the three main types of plate boundaries based on plate movement:

  1️⃣ Convergent: Plates move towards each other

  2️⃣ Divergent: Plates move apart from each other

  3️⃣ Transform: Plates slide past each other horizontally
• Transform boundaries result in earthquakes but little volcanic activity.

  True
• Mountain ranges are formed by the collision and uplift of continental plates at a convergent
• Mid-ocean ridges are formed by seafloor spreading as plates move apart at a divergent
• At convergent boundaries, subduction and mountain building can lead to earthquakes, volcanic eruptions, and tsunamis
• Earthquakes can occur along all types of plate boundaries due to accumulated stress.


  True
• The East African Rift Valley is an example of a divergent boundary where the African plate is splitting apart.


  True
• There are two main types of plate boundaries: convergent and divergent.

  False
• At a convergent boundary, the denser plate is forced under the less dense plate in a process called subduction
• Mountain ranges are often formed at convergent boundaries due to volcanic activity.

  True
• Volcanic activity is common at divergent boundaries.

  True
• Match the boundary type with its associated landforms:

  Convergent ↔️ Mountain ranges

  Divergent ↔️ Mid-ocean ridges

  Transform ↔️ Fault lines
• Plate tectonics is the theory that the Earth's surface is composed of moving plates
• At convergent boundaries, plates move towards each other, leading to subduction, mountain building, and volcanic activity
• The denser plate is always subducted under the less dense plate at convergent boundaries.


  True
• Match the major tectonic landform with its formation process:

  Mountain Ranges ↔️ Collision of continental plates

  Volcanic Arcs ↔️ Subduction of oceanic plate

  Deep Ocean Trenches ↔️ Subduction of denser oceanic plate
• Volcanic arcs are formed by the subduction of an oceanic plate under a continental or oceanic plate at a convergent boundary.


  True
• Rift valleys are formed by the divergence and rifting of continental plates at a divergent boundary.
